Data is pipelined between query stages and over the network reducing latency overhead that one would have if disk I/O were involved. Executing and analyzing analytic workloads Let us start with some simple examples of running queries and analyze the execution. We can either use the dBeaver interface or the watsonx.data CLI.

Usually this location is your workstation, but it could be another service like CP4D. To extract the certificate to your local file system, use the following command in a terminal window. Replace the port and regions.techzone-server.com with the SSH values found in the TechZone reservation. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Credentials notebook. There you will find links to the certificates. Watsonx.data Presto Access When connecting to the Presto engine, choose the PrestoDB driver. Presto Internal Access For local access the following credentials are used: Hostname: localhost Port: 8443 Username: ibmlhadmin Password: password Database: tpch In addition, you need to set the following driver properties: SSL True SSLTrustStorePath /certs/presto-key.jks SSLTrustStorePassword watsonx.data Presto External Access The watsonx.data Presto database requires that the certificate be extracted from the image. See the section above on Connection Certificate for more details. In the following settings, remember to update the Hostname and Port to the values provided in your TechZone reservation. The database connection settings are: Hostname: region.services.cloud.techzone.ibm.com Port: port Username: ibmlhadmin Password: password Database: tpch In addition, you need to set the following driver properties: SSL True SSLTrustStorePath /mydownload/presto-key.jks SSLTrustStorePassword watsonx.data Note : The /mydownload/presto-key.jks value needs to be replaced with the location that you copied the key in the earlier step. Db2 Access When connecting to the Db2 engine, select the Db2 LUW driver. Db2 Internal Access The Db2 server can be accessed on port 50000 inside the virtual machine using the following credentials: Hostname - watsonxdata Port - 50000 Username - db2inst1 Password - db2inst1 Database - gosales SSL - off Db2 External Access When accessing the database outside the virtual machine, you must change the host to region.services.cloud.techzone.ibm.com and the port number based on your TechZone reservation. All the other settings remain the same. Hostname - region.services.cloud.techzone.ibm.com Port - port Username - db2inst1 Password - db2inst1 Database - gosales SSL - off PostgreSQL Access When connecting to the PostgreSQL engine, select the PostgreSQL driver. In order to connect to the PostgreSQL system, you will need to extract the admin password using the following command when connected to the watsonx.data system. cat /certs/passwords You can also retrieve the credentials by opening up the Credentials notebook in the Jupyter notebook service. PostgreSQL Internal Access When accessing the PostgreSQL database in the system, use the following settings. Hostname \u2013 ibm-lh-postgres Port \u2013 5432 Username \u2013 admin Password \u2013 The value that was extracted in the earlier step Database \u2013 gosales PostgreSQL External Access The following credentials are used for remote access. Hostname: regions.techzone-server.com Port: port Username: admin Password: The value that was extracted in the earlier step Database name: gosales MySQL Access When connecting to the MySQL engine, select the MySQL driver. export POSTGRES_PASSWORD=$(docker exec ibm-lh-postgres printenv | grep POSTGRES_PASSWORD | sed 's/.*=//') echo \"Postgres Userid : admin\" echo \"Postgres Password : \" $POSTGRES_PASSWORD echo $POSTGRES_PASSWORD > /tmp/postgres.pw MySQL Internal Access When accessing the MySQL database in the system, use the following settings. Hostname \u2013 watsonxdata Port \u2013 3306 Username \u2013 root Password - password Database \u2013 gosalesdw You must set the allowPublicKeyRetrieval to True for the connection to work with dBeaver. MySQL External Access The following credentials are used for remote access. Hostname: regions.techzone-server.com Port: port Username: root Password - password Database name: gosalesdw You must set the allowPublicKeyRetrieval to True for the connection to work with dBeaver (see above). Adding a Database to watsonx.data When adding a database engine to the watsonx.data system, make sure to change the database display name since that needs to be unique. For instance, when you add gosales database from Db2 to the system, the display name could be gosales as well. However, if you now add the PostgreSQL database to the system, the display name cannot be the same. You may want to differentiate databases with the same name by prefixing them with the database type. For instance, the gosales database could be shown as db2_gosales or pg_gosales so that you keep the names distinct. Once a database has been added, make sure to wait for a few moments before attempting to access the database. The Presto server takes a few moments to start up. To make sure that it is running, run the check_presto command in a terminal window and wait until it says the service is ready. When attempting to view the contents of a new database, the process may take a few minutes to complete. Refresh the browser window if you haven't seen any changes to the display. Accessing watsonx.data via Python In order to access the watsonx.data database (Presto), you will need to install the Presto client using the following command on your local machine. pip3 install presto-python-client Once the installation is complete, extract the certificate from the watsonx.data server that we will use in the connection. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Certificate notebook. Python and Jupyter Connection Code Your Python or Jupyter notebook code will need to import the prestodb library and then connect to watsonx.data using the connect call. import prestodb conn = prestodb.dbapi.connect( host='watsonxdata', port=8443, user='ibmlhadmin', catalog='tpch', schema='tiny', http_scheme='https', auth=prestodb.auth.BasicAuthentication(\"ibmlhadmin\", \"password\") ) conn._http_session.verify = '/certs/lh-ssl-ts.crt' cur = conn.cursor() In the above connection string, you will need to replace the following values: host - watsonxdata when connecting to the image externally, and ibm-lh-presto-svc when connecting internally catalog - What is the name of the catalog that we are accessing schema - The schema inside the catalog that will be used You also need to update the conn._http_session.verify value with the location where you downloaded the lh-ssl-ts.crt file. For internal connections, this value will be /certs/lh-ssl-ts.crt . Once connected, you can run an SQL statement and return the results. cur.execute(\"SELECT * FROM tpch.tiny.customer\") rows = cur.fetchall() The rows variable contains the answer set from the select statement. You can manipulate the row variable to view the results. rows[0] [1, 'Customer#000000001', 'IVhzIApeRb ot,c,E', 15, '25-989-741-2988', 711.56, 'BUILDING', 'to the even, regular platelets. regular, ironic epitaphs nag e'] The PrestoDB driver supports the DBAPI spec. For more details on the use of the DBAPI interface, please refer to https://peps.python.org/pep-0249/ . For instance, if you want to find the description of the columns returned, you would use the description function. cur.description [('custkey', 'bigint', None, None, None, None, None), ('name', 'varchar(25)', None, None, None, None, None), ('address', 'varchar(40)', None, None, None, None, None), ('nationkey', 'bigint', None, None, None, None, None), ('phone', 'varchar(15)', None, None, None, None, None), ('acctbal', 'double', None, None, None, None, None), ('mktsegment', 'varchar(10)', None, None, None, None, None), ('comment', 'varchar(117)', None, None, None, None, None)] Accessing watsonx.data via Pandas Dataframes The following code is required for accessing watsonx.data in Jupyter notebooks. Run the following code inside a notebook code cell. %pip install ipython-sql==0.4.1 %pip install sqlalchemy==1.4.46 %pip install sqlalchemy==1.4.46 \"pyhive[presto]\" The notebook may need a restart of the kernel to pick up the changes to the driver. If you are running in a Jupyter Lab environment, you can use the most current versions of the drivers. %pip install ipython-sql %pip install sqlalchemy %pip install sqlalchemy \"pyhive[presto]\" Once the drivers have been loaded, you will need to extract the certificate from the watsonx.data server that we will use in the connection. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Certificate notebook. In your Jupyter notebook, you will need to import a number of libraries. import pandas as pd import sqlalchemy from sqlalchemy import create_engine Create a notebook cell which will contain all the credentials that are required to connect. Change the catalog , schema and certfile to your values. userid = \"ibmlhadmin\" password = \"password\" hostname = \"watsonxdata\" port = \"8443\" catalog = \"tpch\" schema = \"tiny\" certfile = \"/certs/lh-ssl-ts.crt\" connect_args={ 'protocol': 'https', 'requests_kwargs': {'verify': f'{certfile}'} } In the above settings, you will need to replace the following values: hostname - region.services.cloud.techzone.ibm.com when connecting to the image externally, and ibm-lh-presto-svc when connecting internally catalog - What is the name of the catalog that we are accessing schema - The schema inside the catalog that will be used You also need to update the certfile value with the location where you downloaded the lh-ssl-ts.crt file. For internal connections, this value will be /certs/lh-ssl-ts.crt . To create a connection to the database, use the following syntax. engine = create_engine( f\"presto://{userid}:{password}@{hostname}:{port}/{catalog}/{schema}\", connect_args=connect_args ) Now that you have established a connection, you can use the Pandas read_sql_query function to execute a SELECT statement against the database. mypresto = pd.read_sql_query('SELECT * from tpch.tiny.customer',engine) The variable mypresto contains the dataframe generated from the SELECT statement. mypresto You can use the features of Pandas to generate plots of the data in your notebook. First make sure you have matplotlib installed. %pip install matplotlib The following query will compute the total account balance across all nation key values. sumbynation = pd.read_sql_query('SELECT \"nationkey\", sum(\"acctbal\") from tpch.tiny.customer group by \"nationkey\" order by 2',engine) Finally, we plot the results. df.plot(kind=\"bar\", x=\"FirstName\", y=\"LastName\") plt.show() Adding a Service The watsonx.data developer edition includes two open ports which can be used to externalize a service that you create in the image. For instance, you may choose to create a MongoDB or MSSQL container using Docker and want to access this service from your own dBeaver or Mongo tooling. Since port numbers vary between different databases, the watsonx.data system provides two port numbers that can be used by your service. Open Port 1 - Server: region.services.cloud.techzone.ibm.com: Port: 12345 Open Port 2 - Server: region.services.cloud.techzone.ibm.com: Port: 23456 The internal port numbers are 10000 (Port 1) and 10001 (Port 2). The following steps are required to use these ports with your service. Open the local Firewall (Version 1.1.0 Only) Ports 10000/1 are not open by default in the 1.1.0 image. For release 1.1.1, you can skip this step. You must explicitly open ports 10000/1 with the firewall-cmd command. In a command line shell, as the root user, enter the following commands: sudo su - firewall-cmd --add-port={10000/tcp,10001/tcp} --zone=public --permanent firewall-cmd --reload You can use the following command to check that the ports are now open. firewall-cmd --list-ports Create your Service When creating your service, make sure to map the internal Docker port to either port 10000 or 10001. If you cannot remap the port, see the section on port redirection. For instance, the following command will start Microsoft SQLServer in Docker by mapping the host port 10000 to the SQLServer port of 1433 to 10000 ( -p 10000:1443 ). docker run -e \"ACCEPT_EULA=Y\" -e \"MSSQL_SA_PASSWORD=Passw0rd12345678!\" \\ -p 10000:1433 --name mssql-server --hostname mssql-server \\ -d mcr.microsoft.com/mssql/server:2019-latest You can check the port mapping with the following command. docker container ls --format \"table {{.ID}}\\t{{.Names}}\\t{{.Ports}}\" -a | grep mssql-server When creating a connection to this database using an external tool, make sure to use the port number supplied in the reservation details (Open Port 1 is for port 10000 and Open Port 2 is for port 10001). Port Redirection If you already have an existing service mapped to a different port, you can use port redirection to use either port 10000 or 10001. For instance, assume that the previous creation of the SQLServer database used port 1433. docker run -e \"ACCEPT_EULA=Y\" -e \"MSSQL_SA_PASSWORD=Passw0rd12345678!\" \\ -p 1433:1433 --name mssql-server --hostname mssql-server \\ -d mcr.microsoft.com/mssql/server:2019-latest Once the service is up and running, you can redirect the traffic on port 10000/1 to the port of your docker service. firewall-cmd --add-forward-port=port=10000:proto=tcp:toport=1433 --permanent --zone=public firewall-cmd --reload If you need to remove the redirection, use the following command. firewall-cmd --remove-forward-port=port=10000:proto=tcp:toport=1433:toaddr= --permanent --zone=public firewall-cmd --reload Accessing your Service When referring to your service from an external location, always use the port numbers that are provided for Open Port 1 or 2. Open Port 1 - Server: region.services.cloud.techzone.ibm.com: Port: 12345 Open Port 2 - Server: region.services.cloud.techzone.ibm.com: Port: 23456 Your server will be region.services.cloud.techzone.ibm.com and the port number will be either of the two port numbers provided. Remember that this port number will need to be opened in the server and a Docker mapping to the open port or a firewall port redirection will be required.","title":"Database Connections"},{"location":"wxd-connections/#database-connections","text":"There are three database systems that can be accessed inside and outside the virtual machine environment: watsonx.data Presto, Db2 LUW, MySQL and PostgreSQL.

Check out the following websites for a variety of public data sets that you can use. Awesome Public Datasets Kaggle Datasets US Data.Gov UCI Machine Learning Repository US Fuel Economy Note : These sites have not been checked for license restrictions on the use of the data. You are responsible for checking that the data can be used without any licensing requirements. Loading your own data You can use a browser or link to an external file repository (i.e., Box) and download data directly to your workstation. Data can be CSV, Parquet, JSON, or TXT formats. Once the data is on your workstation, use the following steps. Note : You cannot import customer data nor any data that has restrictions associated with its use. Any use of private data is in violation of the terms and conditions of using this image. The first step is to connect to MinIO. Extract the MinIO credentials by using the passwords command: passwords Open your browser and navigate to the MinIO console. Login with object store credentials found above (These will be different for your system). You should see the current buckets in MinIO. If you don't see the buckets, click on Object Browser on the left-hand side panel. Select hive-bucket from the list of buckets. You may see other directories in this list than what is shown above. You will need to create a new path for your data set. Create a new directory name for your data (fuel_economy was used for this example). MinIO will display an empty directory and suggest you load something into it. Use the Upload button on the far right side to point to your dataset on your local machine. In this example, we are using a CSV file for the 2013 fuel economy estimates for automobiles sold in the US. You may need to rename you datasets to eliminate blanks and any other special characters other than \" _ \" or \" - \". The display will show the progress of the upload into the bucket. You may need to refresh your browser to see the file in the bucket. Now that the data has been loaded into a bucket, you can catalog it in the watsonx.data UI. If you created a new bucket for this data set, you will need to register it first in the watsonx.data UI. Instructions for how to do this are found in the Working with Object Store Buckets section. Start by navigating to the watsonx.data UI and look at the Infrastructure manager. Find the bucket where you upload your data set into and note the catalog name that it is associated with. Here we can see that the hive-bucket bucket is associated with the hive_data catalog. In the watsonx.data UI, select the Query workspace (SQL) icon. You will need to create a schema that links to this data set. The format of the command is shown below. DROP SCHEMA catalog.schema_name; CREATE SCHEMA catalog.schema_name WITH ( location = 's3a://your-bucket/data_directory' ); You will need to change the following values: catalog - The catalog that the bucket you are using is associated with schema_name - A schema name to associate your tables with data_directory - The directory in which your file is located your_bucket - The bucket the data physically resides in For the fuel economy example, using mpg as the schema, the SQL would be: DROP SCHEMA hive_data.mpg; CREATE SCHEMA hive_data.mpg WITH ( location = 's3a://hive-bucket/fuel_economy' ); Run this SQL against the Presto engine: The DROP command may fail if the schema doesn't exist, but the CREATE should work. The next step is to define what the table looks like for watsonx.data to be able to query it. The syntax of the CREATE TABLE statement is similar to: CREATE TABLE catalog.schema.tablename ( \"column_name\" \"type\", ... ) WITH ( format = 'CSV', csv_separator = ',', external_location = 's3a://your_bucket/data_directory'); You will need to create a table definition for your CSV file in order to catalog it in watsonx.data. Note that the only data type that is permitted for CSV columns is varchar . This is a restriction of the current driver. Plans are to update it to include other data types over time. If your data set does not include a header row (a row that defines the column names), you will need to create the table definition manually. If the data set does contain a header record, you can use the following Python code to generate a CREATE TABLE statement. You will need to make sure that pandas is available. python3 -m pip install pandas --user Next run the python3 command in the shell to run an interactive Python session. python3 Place the following code into your Python window. def showcsv(catalog, schema, tablename, bucket, directory, csv_in): import pandas as pd df = pd.read_csv(csv_in,na_values=\"-\") df = df.fillna(0) column_headers = list(df.columns.values) print(\"\") print(f\"DROP TABLE IF EXISTS {catalog}.{schema}.{tablename};\") print(f\"CREATE TABLE {catalog}.{schema}.{tablename}\") print(\" (\") comma = \"\" end = \"\" for header in column_headers: print(f\"{comma}\",end=end) comma = \",\" end = \"\\n\" print(f' \"{header}\" varchar',end=\"\") print(f\" )\") print(f\"WITH (\") print(f\" format = 'CSV',\") print(f\" csv_separator = ',',\") print(f\" external_location = 's3a://{bucket}/{directory}'\") print(f\" );\") print(\"\") def makesql(): catalog = input(\"Catalog : \") schema = input(\"Schema : \") table = input(\"Table : \") bucket = input(\"Bucket : \") dir = input(\"Directory : \") csv = input(\"CSV File : \") showcsv(catalog,schema,table,bucket,dir,csv) Gather the following information on your dataset: catalog - The catalog the schema and table are created under ( hive_data ) schema - The schema name that you created to hold your table ( mpg ) table name - The name of the table ( fuel_economy ) bucket - Where the data is located ( hive-bucket ) directory - What directory contains your data ( fuel_economy ) csv_in - The location on your local machine where the csv file is Once you have gathered that, run the following command in your Python window and answer the prompts. makesql() >>> makesql() Catalog : hive_data Schema : mpg Table : fueleconomy Bucket : hive-bucket Directory : fuel_economy CSV File : ~/Downloads/fuel_economy_2013.csv DROP TABLE IF EXISTS hive_data.mpg.fueleconomy; CREATE TABLE hive_data.mpg.fueleconomy ( \"MODEL_YEAR\" varchar, \"MFR_NAME\" varchar, \"DIVISION\" varchar, \"CARLINE\" varchar, \"ENG_DISPL\" varchar, \"CYL\" varchar, \"TRANS_IN_FE_GUIDE\" varchar, \"CITY_FE_CONVENTIONAL_FUEL\" varchar, \"HWY_FE_CONVENTIONAL_FUEL\" varchar, \"COMB_FE_CONVENTIONAL_FUEL\" varchar, \"AIR_ASPIRATION_DESC\" varchar, \"TRANS_DESC\" varchar, \"GEARS\" varchar, \"DRIVE_DESC\" varchar, \"FUEL_UNIT_CONVENTIONAL_FUEL\" varchar, \"FUEL_UNIT_DESC_CONVENTIONAL_FUEL\" varchar, \"ANNUAL_FUEL_COST_CONVENTIONAL\" varchar, \"FUEL_METERING_SYS_DESC\" varchar ) WITH ( format = 'CSV', csv_separator = ',', external_location = 's3a://hive-bucket/fuel_economy' ); Cut and paste the output from the command into the watsonx.data Data Explorer window to create the file. Now you can query the table with the following SQL. Note that the header record still exists in the answer set since we did not remove it from the CSV file.

You will need to make sure that pandas is available. python3 -m pip install pandas --user Next run the python3 command in the shell to run an interactive Python session. python3 Place the following code into your Python window. def showcsv(catalog, schema, tablename, bucket, directory, csv_in): import pandas as pd df = pd.read_csv(csv_in,na_values=\"-\") df = df.fillna(0) column_headers = list(df.columns.values) print(\"\") print(f\"DROP TABLE IF EXISTS {catalog}.{schema}.{tablename};\") print(f\"CREATE TABLE {catalog}.{schema}.{tablename}\") print(\" (\") comma = \"\" end = \"\" for header in column_headers: print(f\"{comma}\",end=end) comma = \",\" end = \"\\n\" print(f' \"{header}\" varchar',end=\"\") print(f\" )\") print(f\"WITH (\") print(f\" format = 'CSV',\") print(f\" csv_separator = ',',\") print(f\" external_location = 's3a://{bucket}/{directory}'\") print(f\" );\") print(\"\") def makesql(): catalog = input(\"Catalog : \") schema = input(\"Schema : \") table = input(\"Table : \") bucket = input(\"Bucket : \") dir = input(\"Directory : \") csv = input(\"CSV File : \") showcsv(catalog,schema,table,bucket,dir,csv) Gather the following information on your dataset: catalog - The catalog the schema and table are created under ( hive_data ) schema - The schema name that you created to hold your table ( mpg ) table name - The name of the table ( fuel_economy ) bucket - Where the data is located ( hive-bucket ) directory - What directory contains your data ( fuel_economy ) csv_in - The location on your local machine where the csv file is Once you have gathered that, run the following command in your Python window and answer the prompts. makesql() >>> makesql() Catalog : hive_data Schema : mpg Table : fueleconomy Bucket : hive-bucket Directory : fuel_economy CSV File : ~/Downloads/fuel_economy_2013.csv DROP TABLE IF EXISTS hive_data.mpg.fueleconomy; CREATE TABLE hive_data.mpg.fueleconomy ( \"MODEL_YEAR\" varchar, \"MFR_NAME\" varchar, \"DIVISION\" varchar, \"CARLINE\" varchar, \"ENG_DISPL\" varchar, \"CYL\" varchar, \"TRANS_IN_FE_GUIDE\" varchar, \"CITY_FE_CONVENTIONAL_FUEL\" varchar, \"HWY_FE_CONVENTIONAL_FUEL\" varchar, \"COMB_FE_CONVENTIONAL_FUEL\" varchar, \"AIR_ASPIRATION_DESC\" varchar, \"TRANS_DESC\" varchar, \"GEARS\" varchar, \"DRIVE_DESC\" varchar, \"FUEL_UNIT_CONVENTIONAL_FUEL\" varchar, \"FUEL_UNIT_DESC_CONVENTIONAL_FUEL\" varchar, \"ANNUAL_FUEL_COST_CONVENTIONAL\" varchar, \"FUEL_METERING_SYS_DESC\" varchar ) WITH ( format = 'CSV', csv_separator = ',', external_location = 's3a://hive-bucket/fuel_economy' ); Cut and paste the output from the command into the watsonx.data Data Explorer window to create the file. Now you can query the table with the following SQL. Note that the header record still exists in the answer set since we did not remove it from the CSV file.

Application Programming Interface (API)**: Application Programming Interface (API) is a programmatic interface for executing functions of an application in an automated or manual fashion without using a CLI or User Interface. Buckets : Buckets are the basic containers that hold your data. Everything that you store in Cloud Storage must be contained in a bucket. You can use buckets to organize your data and control access to your data, but unlike directories and folders, you cannot nest buckets. Catalog : This term may have many meanings depending on context. Review below: Service Catalog - A service catalog is a comprehensive list of cloud computing services that an organization offers its customers. The catalog is the only portion of the company's service portfolio that is published and provided to customers as a support to the sale or delivery of offered services. Data Catalog - A collection of business information describing the available datasets within an organization. Metastore Catalog - A collection of technical and operational metadata allowing a query engine to overlay a virtual table on a collection of discrete data files. Connector Catalog - The named representation of a connector within the virtual warehouse of a presto instance. Command Line Interface (CLI) : A command-line interface (CLI) is a text-based user interface (UI) used to run programs, manage computer files and interact with the computer. dBeaver : DBeaver is a SQL client software application and a database administration tool. For relational databases it uses the JDBC application programming interface to interact with databases via a JDBC driver. For other databases it uses proprietary database drivers. Federation : A federated database is a system in which several databases appear to function as a single entity. Each component database in the system is completely self-sustained and functional. When an application queries the federated database, the system figures out which of its component databases contains the data being requested and passes the request to it. Federated databases can be thought of as database virtualization in much the same way that storage virtualization makes several drives appear as one. MinIO : MinIO is a high-performance, S3 compatible object store. It is built for large scale AI/ML, data lake and database workloads. It runs on-prem and on any cloud (public or private) and from the data center to the edge. MinIO is software-defined and open source under GNU AGPL v3. Object Storage : Object storage is a data storage architecture for storing unstructured data, which sections data into units\u2014objects\u2014and stores them in a structurally flat data environment. Each object includes the data, metadata, and a unique identifier that applications can use for easy access and retrieval. Presto : Presto is a distributed database query engine (written in Java) that uses the SQL query language. Its architecture allows users to query data sources such as Hadoop, Cassandra, Kafka, AWS S3, Alluxio, MySQL, MongoDB and Teradata, and allows use of multiple data sources within a query. Presto is community-driven open-source software released under the Apache License. Presto's architecture is very similar to other database management systems using cluster computing, sometimes called massively parallel processing (MPP).

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access. With the standalone software, users can be added within the console\u2019s Access control page. In the Developer Edition, users can be added using a command line tool. Click on the Access Control icon on the left side of the screen The Access Control panel is divided into Infrastructure and Policies. The initial screen displays the objects that are considered part of the Infrastructure. A user must be granted access to the infrastructure (i.e. Presto engine) in order for them to run queries against any of the schemas in the database. Click on the Policies Tab Your system should not contain any policies at this time. Roles and Policies In this section you will add a new user and provide them with privileges over the infrastructure and data. First start by adding a new user to the watsonx.data system. This lab is using the Developer edition of the watsonx.data software, which means that the Access control panel does not provide a UI for adding users. In order to manage users, the user-mgmt command will need to be used. The user-mgmt command is normally run from a command line in the server. This server includes a user called watsonx with a password of watsonx.data . If you want to add additional users, see the User Administration section at the end of this lab. Access Control To view what users are currently authorized to use the system, select the Access control icon found on the left side of the watsonx.data UI. Click on the Access Control icon on the left side of the screen A list of objects that make up the watsonx.data infrastructure are displayed. You can see that the objects are made up of: Engines Catalogs Buckets In a real-world scenario where a user will be querying data from a table, that user will need to be given a minimum of User access to an engine (to be able to run the query), User access for the catalog associated with the data (to be able to see the schema information associated with the table), and Reader access to the bucket associated with the data (to be able to read the data from object storage). Additionally, a policy has to be created to permit the user to access the table in question. Granting Access Select the presto-01 engine (highlighted in red above) to view the current users that have access to the engine At this point, only the administrative user (ibmlhadmin) can use the Presto engine. Click on the Add Access button to add a new authorized user to the list If you do not see the watsonx userid, or the dropdown is blank, issue the following command in a terminal window. Once the user is added, refresh the browser window and then click on the Add Access button again. sudo /root/ibm-lh-dev/bin/user-mgmt add-user watsonx User watsonx.data The role button has been selected in the dialog to show the role options of Admin, Manager, or User. An Admin user can grant any role to a user, while a Manager can only grant User privileges. Grant watsonx \"user\" privileges and then press Add Close the dialog by clicking on the [x] on the top right of the screen The watsonx user needs to be granted access to a catalog. In this case, the iceberg_data and hive_data catalogs are required for the Presto engine and are implicitly granted to the user. Click on the iceberg_data line to confirm that watsonx has access You should see that watsonx has already been granted access to the catalog. Close the dialog to return to the Access control screen The final step is to grant access to the underlying buckets.

Click Next Here we need to select which catalog to use and then the schemas that the user will be able to access. Select hive_data catalog, and then the ontime schema If you do not see any values being populated on the screen, refresh the browser After selecting the schema, a set of tables associated with the schema will be listed. You can choose which tables can be searched. If you choose an individual table, you can restrict which columns can be searched. Select the ontime table and then select the following columns (you will need to scroll down the page) flightdate reporting_airline flight_number_reporting_airline originairportid destairportid Press the Next button when all columns are selected The Rules dialog allows you to fine-tune what actions can be done by a user against the data. Press the Add Rule button to display the Add Rule dialog Rules can be used to Allow actions or to Deny actions. Allow watsonx to SELECT data from the data, but with no other options Note : In production versions of watsonx.data, you can provide access to a group which makes it simpler to create a set of rules that apply to a group and then add a user to a group. That way a user will inherit the rules that were applied to the group rather than having to create rules for that individual. The developer edition displays GROUP as an option, but it is not implemented. Make sure to select watsonx as the user Press the Add button You can continue to add additional rules to the list. Since we only want the one rule, select the Review button. Press the Review button Confirm that the data objects and rules look correct then press the Create button The selectflights policy is now in place and is actively enforced. Press the Query Workspace Icon Before testing the policy enforcement, use the SQL icon on the left side to navigate to the hive_data catalog and view the schemas that are associated with it. Expand the ontime schema to view the tables and the columns that are available in the ontime table When you connect as watsonx , you will be able to compare what objects can be accessed from that userid. Testing Policy Enforcement To test whether the rules are enforced, you will need to log out of the current watsonx.data UI session. At the top of the Query workspace screen, you will see the user icon on the top right. Click on the user icon to display the logout dialog Log out to the main watsonx.data UI screen You will be prompted to confirm log out. The log in dialog should be displayed.

Note how you have less components in the Infrastructure summary. Navigate to the SQL icon and then select hive_data \u2192 ontime \u2192 ontime You should notice that watsonx was restricted to seeing only the ontime schema in the hive_data catalog. In addition, the user was restricted to accessing one of the tables ( ontime ) and 5 columns. Attempting to run a SELECT statement against all the data will result in a policy error.

In addition, the SQL that they could execute was restricted to specific columns in the table. Before moving onto any other sections, make sure to log out as watsonx and reconnect as the ibmlhadmin user. Click on the user icon to display the logout dialog Log out to the main watsonx.data UI screen You will be prompted to confirm log out. The log in dialog should be displayed. Enter the credentials for the ibmlhadmin user and press Log in Username: ibmlhadmin Password: password Your watsonx.data UI should now display ibmlhadmin . Summary In this section you learned how to add a user to watsonx.data (via a command) and control what objects they are allowed to access. In production versions of watsonx.data, the adding and removal of users is directly handled through the User Interface. User Administration Users can be added to the watsonx.data Developer Edition by using a command line tool called user-mgmt . The syntax of the command is: ./user-mgmt add-user [User | Admin] The values are: username - The name of the user [User|Admin] - The type of user. Note that the type of user is case-sensitive! password - The password for the user. For the purposes of this lab, we are going to use a Jupyter notebook that was specifically created for managing users. Find the URL in your reservation that reads Jupyter Notebook - Server: http://region.services.cloud.techzone.ibm.com:xxxx/notebooks/Table_of_Contents.ipynb and click on it The initial screen will request that you enter a password. The password is watsonx.data . Enter watsonx.data as the password Once you have authenticated, the Table of Contents is displayed. Click on the Arrow on the User Administration tile. The Administration notebook is displayed. A Jupyter notebook contains multiple \"cells\" which can contain a couple of different objects: Code - A cell that contains code that will run (usually Python) Markdown - A cell that contains text and formatting using a language called Markdown In this lab, we need to run code that is found in the notebook. You can tell which text is a code cell because of the [ ]: beside the cell and probably because it has some code in the cell! Before executing the contents of the cell, you must click on the cell (place focus on the cell). You can tell when the focus is on the code cell because it will be highlighted with a thin blue box. To \"execute\" the contents of the cell, you must either hit the run button icon \u25ba or Shift-Return on your keyboard. Modify any values and run the contents of the cell which contains the add-user command A message indicating that a user was successfully added will be displayed in the notebook.

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access.

Before describing the contents of the UI, some explanation of the watsonx.data objects are necessary. Watsonx.data is based on open-source Presto DB, a distributed query engine that enables querying data stored in open file formats using open table formats for optimization and performance. There are four types of objects that are commonly referred to in the Presto DB environment: Engine \u2013 Each watsonx.data installation has at least one Presto DB engine which is used for querying the data. An installation can have more than one Presto engine to improve performance, isolate workloads, or test different versions. Additional engines can include Apache Spark, which provides capabilities for reading and transforming many types of data. Catalogs \u2013 Catalogs contain information about tables, files, and objects that are found in databases or file systems. Catalogs can be specific to the type of object being manipulated (Apache Hive, Apache Iceberg). Buckets \u2013 Buckets refer to Cloud Object Storage (MinIO, AWS S3, IBM COS, etc...) that contain the files and objects that you will catalog and eventually query with an engine. Database \u2013 These represent 3rd party databases that are used to query tables that are in a vendor\u2019s proprietary format (Oracle, Db2, Netezza, etc...). Services - Services refer to additional components in watsonx.data (like Milvus) which provide specific features that are not found in the watsonx.data engine itself. There are two built-in catalogs provided with watsonx.data: Hive_data \u2013 This catalog contains references to objects that are immutable. These are objects such as CSV (comma-separated values), Text, JSON, and Apache Parquet files which are read-only. Iceberg_data \u2013 This catalog contains references to tables that are in Apache Iceberg format. These tables are optimized for space usage and query performance and can be updated. Now that you know what the various components are, we can look at the information found in the Infrastructure manager. Infrastructure Manager UI The Infrastructure manager page opens with a graphical canvas view of the different infrastructure components currently defined in this watsonx.data environment. Click on the Infrastructure icon on the left side of the screen The Infrastructure manager provides a helpful visualization of the current system. These components are: Engines (blue layer) \u2013 The query engines that will access the data. Catalogs (purple layer) \u2013 Catalogs contain metadata about the objects found in buckets or databases. Each catalog is associated with one or more engines. An engine can\u2019t access data in a bucket or a remote database unless the corresponding catalog is associated with the engine. Buckets (pink layer) \u2013 An object-store that contains data (i.e., MinIO, AWS S3, Cloud-Object Storage). Each bucket is associated with a catalog (with a 1:1 mapping). When a bucket is added to watsonx.data, a catalog is created for it at the same time, based on input from the user. Databases (blue layer) \u2013 Specialty Database engines. If a database connection is added (for federation purposes), a catalog is created for that database connection as well. Services (green layer) - Specialty Services. In this system, a Milvus Vector database has been provisioned as an extra service. The diagram can become complex as the number of data sources and engines increases. You can use the magnifier in the bottom right corner to fit the diagram onto the screen or to focus in on a portion of the diagram. You have the option of auto-arranging, zooming in, zooming out, or fitting the diagram to the screen. Click on the Zoom out (-) button and then Zoom in (+) The following is an example of a complex system where the diagram was fit to the screen. You can also use your mouse to click on part of the screen and \u201cmove\u201d it to center the diagram.

Click on each tab in the table view to see the contents Reset back to the topology view. Switch back to topology view to the show the entire diagram Exploring the Contents of a Catalog Hover your mouse over the hive_data catalog As you hover your mouse over the hive_data catalog in the topology view, the elements (engine, catalogs, buckets, databases) that are connected will be highlighted on the screen. To explore the contents of the hive_data catalog, click on the catalog icon. Click on the hive_data catalog icon Detailed information about the catalog is displayed on the screen. There are additional tabs at the top of the screen that provide information on the data objects that are cataloged and the access control for those objects. Click on the Data Objects tab The Data Objects tab provides detailed information on the contents of the catalog. This provides an easy way to explore the contents of the catalog. Click on the Access Control Tab The access control tab provides a list of users and groups that are authorized to access this bucket. The system currently has two registered users in it (your system may have only one). Close the dialog by pressing the [x] in the corner, or using the Escape key You should now see the topology view of the system. Exploring the Contents of a Bucket Hover your mouse over the hive_data bucket Instead of selecting the catalog, click on the hive-bucket at the bottom of the screen. Watsonx.data is a unified analytics repository, and it starts like most data management solutions with storage. The most pervasive storage solution in the marketplace is object store. There are several solutions in the marketplace providing low cost, unlimited scalability, extreme durability, and high throughput. The Developer edition of watsonx.data uses MinIO as an S3-complaint object store. The bucket hive-bucket resides in MinIO storage and is cataloged in watsonx.data. There are three additional buckets, iceberg-bucket used to store Iceberg tables, wxd-system used for control information, and wxd-milvus for Milvus vector database storage. There are three tabs in the bucket details pane: Details Objects Access Control Click on the Objects tab The objects tab provides a view into the physical files that are found in the bucket. There is a hierarchy of directories that make up the contents of the bucket. At the highest level we have the bucket itself, or hive-bucket in this example. The bucket contains a number of directories: gosales, ontime, taxi, and hive_sql. The display will indicate the number of directories or files that are found in the directory. This first level of directories map to the schema name. In the watsonx.data system, the schema ontime has the tables cataloged underneath the ontime directory. Click on the ontime directory The directories in this panel map to the table names. For instance, the directory aircraft is used to store the aircraft table. Click on the aircraft directory The physical file that is used to represent the aircraft types is found in this file. An iceberg table will include additional information containing versioning, statistics and partitioning of the table. Close the bucket dialog by pressing the [x] in the corner Adding Resources to watsonx.data To view how engines, buckets, and databases can be added, click on the Add component on the top right of the Infrastructure screen and select Create Engine. Select Add component \u2192 Database A dialog will appear that provides options for adding another bucket or database to the system. A production version of watsonx.data would also include an option for adding another compute engine to the system. The Database Type drop-down menu supports a number of databases.

Before describing the contents of the UI, some explanation of the watsonx.data objects are necessary. Watsonx.data is based on open-source Presto DB, a distributed query engine that enables querying data stored in open file formats using open table formats for optimization and performance. There are four types of objects that are commonly referred to in the Presto DB environment: Engine \u2013 Each watsonx.data installation has at least one Presto DB engine which is used for querying the data. An installation can have more than one Presto engine to improve performance, isolate workloads, or test different versions. Additional engines can include Apache Spark, which provides capabilities for reading and transforming many types of data. Catalogs \u2013 Catalogs contain information about tables, files, and objects that are found in databases or file systems. Catalogs can be specific to the type of object being manipulated (Apache Hive, Apache Iceberg). Buckets \u2013 Buckets refer to Cloud Object Storage (MinIO, AWS S3, IBM COS, etc...) that contain the files and objects that you will catalog and eventually query with an engine. Database \u2013 These represent 3rd party databases that are used to query tables that are in a vendor\u2019s proprietary format (Oracle, Db2, Netezza, etc...). Services - Services refer to additional components in watsonx.data (like Milvus) which provide specific features that are not found in the watsonx.data engine itself. There are two built-in catalogs provided with watsonx.data: Hive_data \u2013 This catalog contains references to objects that are immutable. These are objects such as CSV (comma-separated values), Text, JSON, and Apache Parquet files which are read-only. Iceberg_data \u2013 This catalog contains references to tables that are in Apache Iceberg format. These tables are optimized for space usage and query performance and can be updated. Now that you know what the various components are, we can look at the information found in the Infrastructure manager.","title":"Infrastructure Manager"},{"location":"wxd-intro-infrastructure/#infrastructure-manager-ui","text":"The Infrastructure manager page opens with a graphical canvas view of the different infrastructure components currently defined in this watsonx.data environment.

These components are: Engines (blue layer) \u2013 The query engines that will access the data. Catalogs (purple layer) \u2013 Catalogs contain metadata about the objects found in buckets or databases. Each catalog is associated with one or more engines. An engine can\u2019t access data in a bucket or a remote database unless the corresponding catalog is associated with the engine. Buckets (pink layer) \u2013 An object-store that contains data (i.e., MinIO, AWS S3, Cloud-Object Storage). Each bucket is associated with a catalog (with a 1:1 mapping). When a bucket is added to watsonx.data, a catalog is created for it at the same time, based on input from the user. Databases (blue layer) \u2013 Specialty Database engines. If a database connection is added (for federation purposes), a catalog is created for that database connection as well. Services (green layer) - Specialty Services.

For example, there is usually an interactive command line interface (CLI) that lets users run SQL statements from a command terminal. Applications can use JDBC (Java Database Connectivity) to connect to the data store and run SQL statements. The watsonx.data user interface includes an SQL interface for building and running SQL statements. This is called the Query workspace. Users can write or copy in their own SQL statements, or they can use templates to assist in building new SQL statements. Click on the Query Workspace icon on the left side of the screen The Query workspace will have a similar layout to the Data Manager screen, where you can navigate through the catalogs associated with the selected engine. The SQL work area is found to the right of the catalog and table names. You can type, paste, or use saved workspaces to enter SQL (Structured Query Language) commands into this window. An SQL statement instructs the database engine what records to look for in one or more tables. The Query workspace provides several pre-built SQL statements that can be generated for tables already cataloged in the system. In the Data Manager lab, the Data sample tab was used to view a subset of the data in the airline_delay_cause table. This data can be generated in the Query Workspace window by using a prebuilt SQL generator. Expand the hive_data catalog by clicking on the \u25ba beside the hive_data name You should now see all the schemas associated with the catalog, including the ontime schema. Expand the ontime schema by pressing \u25ba beside the schema name The ontime schema includes 5 tables. Hover your mouse over the ontime table name When your mouse hovers over a table name, two icons will become visible. The first icon the refresh symbol \u21ba . The refresh icon forces the watsonx.data UI to retrieve details about the schema or table. Note that watsonx.data does not always reflect the status of tables in the display. The refresh process in not synchronous (i.e., it does not know that an update may have occurred to a table), so changes are not immediately shown in the display. The second icon </> is used to display query templates. Click on the query template icon when it appears on the ontime table line The menu provides four templates for your table: Generate Path \u2013 The path description (or location) of the object. Generate Select \u2013 An SQL statement that will return the contents of the table. Generate Alter \u2013 An SQL statement (DDL \u2013 Data Definition Language) used to alter characteristics of the table, like adding a column. Generate Drop \u2013 An SQL statement used to remove the object from the system. Select the Generate SELECT option The system has populated the SQL window with the catalog name, the schema and the table name. This SQL will retrieve all the columns of the table and limit the output to 10 rows (LIMIT 10). The Run on presto-01 button is highlighted at the far right of the SQL window. The button will reflect which engine watsonx.data will run your query on. There is a pulldown menu beside the button that provides an option to run the query to the point where your cursor is on the text, or from where your cursor is on the text. You can use these options to run portions of an SQL statement when you are debugging results. In this instance, you just want to run the query and display the results. Press the Run on presto-01 button and wait for the results to return Near the middle of the screen, you will see the statement that was executed, the run time, and the success or failure of the statement. The result set (if there is one) is displayed below the SQL statement. An export icon \u2913 is found on the far-right side of the result set. Clicking on the export icon will download the results as a CSV file on your workstation.

Summary This chapter explored the use of the Query Workspace to run SQL commands, generate queries, and determine how the optimizer ran a query. In addition, the ability to store and retrieve SQL was used.","title":"Query Workspace"},{"location":"wxd-intro-queryworkspace/#query-workspace","text":"Databases and query engines such as Presto have multiple ways that users can interact with the data. For example, there is usually an interactive command line interface (CLI) that lets users run SQL statements from a command terminal. Applications can use JDBC (Java Database Connectivity) to connect to the data store and run SQL statements. The watsonx.data user interface includes an SQL interface for building and running SQL statements. This is called the Query workspace. Users can write or copy in their own SQL statements, or they can use templates to assist in building new SQL statements. Click on the Query Workspace icon on the left side of the screen The Query workspace will have a similar layout to the Data Manager screen, where you can navigate through the catalogs associated with the selected engine. The SQL work area is found to the right of the catalog and table names. You can type, paste, or use saved workspaces to enter SQL (Structured Query Language) commands into this window. An SQL statement instructs the database engine what records to look for in one or more tables. The Query workspace provides several pre-built SQL statements that can be generated for tables already cataloged in the system. In the Data Manager lab, the Data sample tab was used to view a subset of the data in the airline_delay_cause table. This data can be generated in the Query Workspace window by using a prebuilt SQL generator. Expand the hive_data catalog by clicking on the \u25ba beside the hive_data name You should now see all the schemas associated with the catalog, including the ontime schema. Expand the ontime schema by pressing \u25ba beside the schema name The ontime schema includes 5 tables. Hover your mouse over the ontime table name When your mouse hovers over a table name, two icons will become visible. The first icon the refresh symbol \u21ba . The refresh icon forces the watsonx.data UI to retrieve details about the schema or table. Note that watsonx.data does not always reflect the status of tables in the display. The refresh process in not synchronous (i.e., it does not know that an update may have occurred to a table), so changes are not immediately shown in the display. The second icon </> is used to display query templates. Click on the query template icon when it appears on the ontime table line The menu provides four templates for your table: Generate Path \u2013 The path description (or location) of the object. Generate Select \u2013 An SQL statement that will return the contents of the table. Generate Alter \u2013 An SQL statement (DDL \u2013 Data Definition Language) used to alter characteristics of the table, like adding a column. Generate Drop \u2013 An SQL statement used to remove the object from the system. Select the Generate SELECT option The system has populated the SQL window with the catalog name, the schema and the table name. This SQL will retrieve all the columns of the table and limit the output to 10 rows (LIMIT 10). The Run on presto-01 button is highlighted at the far right of the SQL window. The button will reflect which engine watsonx.data will run your query on. There is a pulldown menu beside the button that provides an option to run the query to the point where your cursor is on the text, or from where your cursor is on the text. You can use these options to run portions of an SQL statement when you are debugging results. In this instance, you just want to run the query and display the results. Press the Run on presto-01 button and wait for the results to return Near the middle of the screen, you will see the statement that was executed, the run time, and the success or failure of the statement. The result set (if there is one) is displayed below the SQL statement. An export icon \u2913 is found on the far-right side of the result set. Clicking on the export icon will download the results as a CSV file on your workstation. Select the Details tab in the result set window This dialog provides more information on the execution of the SQL statement. If you want additional details on the query execution plan, you can press the Explain button beside the Run on presto-01 button.

Exit from the Sandbox. exit MinIO CLI The MinIO Client mc command line tool provides an alternative to UNIX commands like ls , cat , cp , mirror , and diff with support for both file systems and Amazon S3-compatible cloud storage services. The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior. Complete details and restrictions around the use of the CLI command can be found on the MinIO Client page. You can use the MinIO CLI from a variety of clients. The MinIO ports are open in the developer edition image, which provides an alternative to loading data directly from your workstation rather than using the MinIO UI interface. Minio System Alias Before running commands against the MinIO server, an alias must be created that includes the access and secret key. The values can be extracted from the system by listing the contents of the /certs/passwords file or by running the passwords command as the root user. cat /certs/passwords The values for the MinIO access and secret key can also be exported with the following code: export LH_S3_ACCESS_KEY=$(docker exec ibm-lh-presto printenv | grep LH_S3_ACCESS_KEY | sed 's/.*=//') export LH_S3_SECRET_KEY=$(docker exec ibm-lh-presto printenv | grep LH_S3_SECRET_KEY | sed 's/.*=//') echo \"MinIO Userid : \" $LH_S3_ACCESS_KEY echo \"MinIO Password: \" $LH_S3_SECRET_KEY The alias command has the following syntax: mc alias set alias-name hostname:port access_key secret_key For a local connection, we will use the following values: Alias Name - watsonxdata Hostname \u2013 watsonxdata Port \u2013 9000 Access Key \u2013 $LH_S3_ACCESS_KEY Secret Key - $LH_S3_SECRET_KEY If you are using an external client to connect to the MinIO service, you will need the URL and Port number from the TechZone reservation. The access key and secret key will be the same values that are found above. Hostname \u2013 region.services.cloud.techzone.ibm.com Port \u2013 12345 The alias for local access is found below. mc alias set watsonxdata http://watsonxdata:9000 $LH_S3_ACCESS_KEY $LH_S3_SECRET_KEY Added `watsonxdata` successfully. List Buckets The mc command provides us with a number of commands that allows us to manage buckets and files within them. The following command checks to see what buckets currently exist in the system. mc ls tree watsonxdata [2023-09-29 14:38:19 EDT] 0B hive-bucket/ [2023-09-29 14:38:19 EDT] 0B iceberg-bucket/ You can view the contents of a bucket by traversing down the path. mc ls tree watsonxdata/hive-bucket [2023-10-13 10:34:36 EDT] 0B gosalesdw/ [2023-10-13 10:34:36 EDT] 0B hive_sql/ [2023-10-13 10:34:36 EDT] 0B ontime/ [2023-10-13 10:34:36 EDT] 0B taxi/ Create a Bucket At this point we will create a new bucket to hold some data. Use the mb (make bucket) command. The command requires the alias name for the MinIO connection followed by the name of the bucket. mc mb alias-name/new-bucket The following code will create a new bucket in the system called sampledata . mc mb watsonxdata/sampledata Bucket created successfully `watsonxdata/sampledata`. We can double check that the bucket it there. mc ls tree watsonxdata [2023-09-29 14:38:19 EDT] 0B hive-bucket/ [2023-09-29 14:38:19 EDT] 0B iceberg-bucket/ [2023-10-13 10:39:47 EDT] 0B sampledata/ Loading Data One of the most powerful features of the MinIO CLI is its ability to load data directory from your workstation into the bucket, rather than having to use the MinIO UI. It is also significantly faster than using the UI interface. The next example will load data into the bucket that was just created. The directory that we will be using to load data from is called /sampledata and found in the root directory of the watsonx.data server. ls /sampledata/csv gosales ontime taxi Next we will load the data from each one of these directories into the sampledata bucket. The mc command allows you to select which files to place into a bucket, or an entire directory with recursion. In this case we are loading all three directories the files into the bucket. Note the use of the / at the end of the directory name to prevent the directory name csv from being used as the high-level directory name in the target bucket. mc cp --recursive /sampledata/csv/ watsonxdata/sampledata/ ...data/csv/taxi/taxi.csv: 306.16 MiB / 306.16 MiB \u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501 147.91 MiB/s 2s We can double-check that our files are there with the --files option: mc tree --files watsonxdata/sampledata/ watsonxdata/sampledata/ \u251c\u2500 gosales \u2502 \u251c\u2500 DIST_INVENTORY_FACT.csv \u2502 \u251c\u2500 DIST_PRODUCT_FORECAST_FACT.csv \u2502 \u251c\u2500 DIST_RETURNED_ITEMS_FACT.csv \u2502 \u251c\u2500 DIST_RETURN_REASON_DIM.csv .... \u2502 \u251c\u2500 EMP_EMPLOYEE_DIM.csv \u2502 \u251c\u2500 SLS_SALES_TARG_FACT.csv \u2502 \u251c\u2500 gosales_createtable.sql \u2502 \u2514\u2500 gosales_load_postgres.sql \u251c\u2500 ontime \u2502 \u251c\u2500 aircraft.csv \u2502 \u251c\u2500 airline_id.csv \u2502 \u251c\u2500 airport_id.csv \u2502 \u251c\u2500 cancellation.csv \u2502 \u2514\u2500 ontime.csv \u2514\u2500 taxi \u2514\u2500 taxi.csv Delete a File or Bucket Use the rb (Remove bucket) command to remove a bucket and its contents. You can remove individual objects by using the rm (Remove) command by fully qualifying the object. The next command will remove the ontime.csv file from the ontime folder. mc rm watsonxdata/sampledata/ontime/ontime.csv Removed `watsonxdata/sampledata/ontime/ontime.csv`. The delete bucket command will fail if you still have data in the bucket. mc rb watsonxdata/sampledata mc: `watsonxdata/sampledata` is not empty. Retry this command with \u2018--force\u2019 flag if you want to remove `watsonxdata/sampledata` and all its contents Adding the --force option will remove the bucket and all the data in it.

The port number is referred to as port in the command below, while the server will be referred to as region.services.cloud.techzone.ibm.com . Replace these values with those found in your reservation.

You can have multiple connections into the machine at any one time. It will be easier to cut-and-paste commands into a local terminal shell. The VM Remote Console does not support cut-and-paste operation from outside the virtual console environment. Open a terminal window and use the following syntax to connect as the watsonx userid. ssh -p port watsonx@region.services.cloud.techzone.ibm.com The port number and server name are provided as part of the TechZone reservation details.

System Utilities There are several commands that have been added to the watsonx.data developer edition to make it easier to manage the system. These commands are not part of the original installation, but are provided as a convenience for managing the system. All commands require that you connect to the server as the root user. Use the following commands to connect to the watsonx.data system. SSH into the watsonx.data server ssh -p port watsonx@region.services.cloud.techzone.ibm.com Password is watsonx.data . Next switch to the root userid. Switch to the root user sudo su - As the root user, switch to the bin directory. Switch to the bin directory cd /root/ibm-lh-dev/bin Watsonx.data Shutdown Use the stop-watsonx command to stop the watsonx.data system. Watsonx.data shutdown stop-watsonx The stop-watsonx command will stop the Milvus service before stopping the watsonx.data services. If you stop watsonx.data prior to Milvus, the watsonx.data catalog will not be properly updated with the Milvus status, and error messages will be generated about invalid SQL insert statements. This is caused by the catalog service (hosted in PostgreSQL) becoming unavailable because of it being shutdown. You can manually stop the service using either of these commands: Stop watsonx.data service systemctl stop watsonx.service Alternatively, you can use the following commands. You must be in the /root/ibm-lh-dev/bin directory to issue these commands. Stop watsonx.data using direct commands cd /root/ibm-lh-dev/bin ./stop-milvus ./stop Make sure you follow the exact sequence of commands or else you will get a shutdown error with Milvus. Watsonx.data Startup To start the watsonx.data system, use the start-watsonx command. Watsonx.data startup start-watsonx The start-watsonx command will start watsonx.data service before the Milvus service. If you start Milvus prior to starting watsonx.data, the watsonx.data catalog will not be properly updated with the Milvus status, and error messages will be generated about invalid SQL insert statements. You can manually start the service using either of these commands: Start watsonx.data service systemctl start watsonx.service Alternatively, you can use the following commands. You must be in the /root/ibm-lh-dev/bin directory to issue these commands. Start watsonx.data using direct commands cd /root/ibm-lh-dev/bin export LH_RUN_MODE = diag ./start ./start-milvus Startup time Using the systemctl or start command will take a few minutes to complete. There will not be any status messages displayed when using the systemctl command, so if you want to watch the startup sequence, use the start command instead. You must set LH_RUN_MODE to diag to open up the ports in the various watsonx.data containers. If you do not set this environment variable, you will not be able to access several services externally. System Status You can check the status with the following command. System Status ./status.sh --all Output will look similar to: using /root/ibm-lh-dev/localstorage/volumes as data root directory for user: root/1001 infra config location is /root/ibm-lh-dev/localstorage/volumes/infra lhconsole-ui running 0.0.0.0:9443->8443/tcp, :::9443->8443/tcp lhconsole-nodeclient-svc running 3001/tcp lhconsole-javaapi-svc running 8090/tcp lhconsole-api running 3333/tcp, 8081/tcp ibm-lh-presto running 0.0.0.0:8443->8443/tcp, :::8443->8443/tcp ibm-lh-hive-metastore running ibm-lh-postgres running 5432/tcp ibm-lh-minio running Stop and Start Presto If you need to start or stop the Presto engine, use the following commands.

The schemas will take a few seconds to load. Select the workshop schema. Select customer from the list. The display will show the columns associated with this table. On the bottom right-hand corner is a button named CREATE DATASET AND CREATE CHART. Press that to display the following panel. To create a simple Bar Chart, we start by selecting the Bar Chart icon. If you click it once it displays information about the chart type. If you double-click it, the chart builder screen will display. Click on the mktsegment field and drag it into the DIMENSIONS field. Then drag the acctbal field into the METRICS field. The program will ask how the field is to be computed. Select AVG from the list and SAVE. Now press the CREATE CHART button found at the bottom of the screen. Try to create different charts/dashboards if you have time. When you are finished using Apache Superset, press CTRL-C (Control-C) in the terminal window that you used to start it. This will stop the program and release the resources it is using. If you press CTRL-C twice, it immediately kills the program, but it may lose some of the work that you may have done.","title":"Apache Superset"},{"location":"wxd-superset/#reportingdashboarding-using-apache-superset","text":"Apache Superset is not a part of watsonx.data and is only used to demonstrate the capability to connect to watsonx.data from other BI/Reporting tools.

Here is a list of common questions, problems, and potential solutions. What are the passwords for the services A SQL Statement failed but there are no error messages Apache Superset isn't Starting Apache Superset screens differ from the lab Too many incorrect logins using VNC and now I'm blocked Presto doesn't appear to be working Displaying Db2 Schema is failing Queries are failing with a 400 code Queries are failing with a 200 or 500 code Queries are failing with memory errors SSH, VNC and watsonx.data UI are not working No access to Presto/Minio UI after restart Firefox and Chrome freeze when connecting to MinIO What are the passwords for the services? See the section on Passwords . You can get all passwords for the system when you are logged in as the watsonx user by using the following command. cat /certs/passwords You can also use the Jupyter notebook link to display the userids and passwords for the services. A SQL Statement failed, but there are no error messages You need to use the Presto console and search for the SQL statement. Click on the Query ID to find more details of the statement execution and scroll to the bottom of the web page to see any error details. Apache Superset isn't Starting If Superset doesn't start for some reason, you will need to reset it completely to try it again. First make sure you are connected as the watsonx user not root . Make sure you have stopped the terminal session that is running Apache Superset. Next remove the Apache Superset directory. sudo rm -rf /home/watsonx/superset We remove the docker images associated with Apache Superset. If no containers or volumes exist you will get an error message. docker ps -a -q --filter \"name=superset\" | xargs docker container rm --force docker volume list -q --filter \"name=superset\" | xargs docker volume rm --force Download the superset code again. git clone https://github.com/apache/superset.git The docker-compose-non-dev.yml file needs to be updated so that Apache Superset can access the same network that watsonx.data is using. cd ./superset cp docker-compose-non-dev.yml docker-compose-non-dev-backup.yml sed '/version: \"3.7\"/q' docker-compose-non-dev.yml > yamlfix.txt cat <<EOF >> yamlfix.txt networks: default: external: True name: ibm-lh-network EOF sed -e '1,/version: \"3.7\"/ d' docker-compose-non-dev.yml >> yamlfix.txt We update the Apache Superset code to version 2.1.0 . sed 's/\\${TAG:-latest-dev}/2.1.0/' yamlfix.txt > docker-compose-non-dev.yml Use docker-compose to start Apache Superset. nohup docker compose -f docker-compose-non-dev.yml up & The nohup command will issue a message indicating that output will be directed to the nohup.out file. It takes some time for the service to start, so be patient! You can view any output from the Apache Superset system by viewing the nohup.out file in the directory where you installed superset. Apache Superset screens differ from the lab The Apache Superset project makes frequent changes to the types of charts that are available. In some cases they remove or merge charts. Since these charts changes are dynamic, we are not able to guarantee that our examples will look the same as what you might have on your system. Presto doesn't appear to be working If you find that the watsonx.data UI is generating error messages that suggest that queries are not running, or that the Presto service is dead, you can force a soft restart of Presto with the following command: docker restart ibm-lh-presto This will restart the Presto server. If you find that does not fix your problem, you will need to do a hard reset using the following commands: sudo su - cd /root/ibm-lh-dev/bin ./stop_service ibm-lh-presto ./start_service ibm-lh-presto check_presto The command will wait until the service is running before exiting. Displaying Db2 Schema is failing Occasionally when attempting to expand the Db2 catalog (schema), the watsonx.data UI will not display any data or issue an error message. You can try refreshing the browser (not the refresh icon inside the UI) and try again. If you find that this is failing again, open the Query workspace and run the following SQL (replace db2_gosales with the name you cataloged the database with). select count(*) from db2_gosales.gosalesdw.go_org_dim The result should be 123 and hopefully the tables that are part of the schema will display for you. Queries are failing with a 400 code The watsonx.data UI will log you out after a period of inactivity, but doesn't tell you that this has happened. When you attempt to run a query, the error that is returned (400) indicates that you need to log back in again. Queries are failing with a 200 or 500 code A 500 code may indicate the watsonx.data UI has a problem connecting with the Presto engine. First log out of the console and trying logging back on. If that fails to solve the problem, you will need to reboot the console. Open up a terminal window into the server: As the root user, restart the docker container that is running the watsonx.data UI. docker restart lhconsole-nodeclient-svc Queries fail become of insufficient memory If you are running a complex query, you may get an error message similar to \"Query exceeded per-node user memory limit\" or a something similar. Watsonx.data (Presto) attempts to limit the amount of resources being using in a query and will stop a query if it exceeds a certain threshold. You can change the behavior of the system by making the following changes. Note : During this step you will disconnect anyone running a query on the server. What you need to do is make a change to the configuration settings of the Presto engine. AS the root user, enter the docker container for the presto engine: docker exec -it ibm-lh-presto /bin/bash Next, copy the original config file to a safe place in case we make an error: cp /opt/presto/etc/config.properties /opt/presto/etc/config.properties.backup Then update the properties file. cat >> /opt/presto/etc/config.properties << EOL experimental.spiller-spill-path=/tmp experimental.spiller-max-used-space-threshold=0.7 experimental.max-spill-per-node=10GB experimental.query-max-spill-per-node=10GB experimental.spill-enabled=true query.max-memory=10GB query.max-memory-per-node=10GB query.max-total-memory-per-node=10GB query.max-total-memory=10GB EOL Doublecheck that it worked. cat /opt/presto/etc/config.properties | grep experimental experimental.max-spill-per-node=10GB experimental.query-max-spill-per-node=10GB experimental.spill-enabled=true experimental.spiller-max-used-space-threshold=0.7 experimental.spiller-spill-path=/tmp If it is all good then exit the container. exit And now we restart the container. Make sure that you don't impact other users! docker restart ibm-lh-presto Now try running your query again. Note : Once you make this change, only restart presto using the above command, otherwise you will lose the changes. Too many incorrect logins using VNC and now I'm blocked from connecting If you lock yourself out of VNC because of too many incorrect logins, you can reset the service with the following commands. Connect as the root user then run the following command and you should be able to log in again. systemctl restart vncserver@:1 exit SSH, VNC and watsonx.data UI are not working Symptoms: You've tried to use SSH to log into the system, and you get a timeout error. All the Web-based UIs (watsonx.data UI, Presto) fail. Find your email message that contains details of your reservation. Details of what the reservations and the page containing details of the reservation can be found in the Accessing the reservation section. Once the details appear, scroll down to the bottom of the web page, and you will see the VM Remote Console button. You can access the logon screen of the virtual machine by pressing the VM Remote Console button. Clicking on this button will display the logon screen for the server. If you see this screen, the system is running and there is something wrong the watsonx.data service (see instructions below). If you see the following screen: This means your server has been turned off. Click on the Power on button. Make sure to press the Yes button to turn the power on! In a few minutes you should see the logon screen again. Wait for a few minutes for all the services to start, and then you will be able to use SSH, VNC, and watsonx.data UI. Reset watsonx.data If you can log into the watsonx userid using the VM Remove console, you can reset the watsonx.data server with the following steps. SSH into the server as the root user. Then switch to the development code bin directory. cd /root/ibm-lh-dev/bin Check the status of the system with the following command. ./status.sh --all Output will look similar to: using /root/ibm-lh-dev/localstorage/volumes as data root directory for user: root/1001 infra config location is /root/ibm-lh-dev/localstorage/volumes/infra lhconsole-ui running 0.0.0.0:9443->8443/tcp, :::9443->8443/tcp lhconsole-nodeclient-svc running 3001/tcp lhconsole-javaapi-svc running 8090/tcp lhconsole-api running 3333/tcp, 8081/tcp ibm-lh-presto running 0.0.0.0:8443->8443/tcp, :::8443->8443/tcp ibm-lh-hive-metastore running ibm-lh-postgres running 5432/tcp ibm-lh-minio running If the any of the services are not running, you will need to restart the system with the following set of commands. cd /root/ibm-lh-dev/bin ./stop.sh export LH_RUN_MODE=diag ./start.sh Wait for all services to start and then check to see if you can connect to the watsonx.data UI. No access to Presto/Minio UI after restart If you are using a TechZone image that has been suspended, or restarted, you may come across a situation where you are unable to connect to any service that uses the http protocol. The watsonx.service needs to have a diagnostic flag set that opens up these ports, and sometimes this diagnostic setting is not being updated. To manually stop and start the system, you will need to connect with root user privileges and run the following commands: sudo su - cd /root/ibm-lh-dev/bin ./stop.sh export LH_RUN_MODE=diag ./start.sh This set of commands will stop all the services in watsonx.data and restart them in diagnostic mode. This will now open the http ports for use. Firefox and Chrome freeze when connecting to MinIO Firefox and Chrome on OSX will occasionally freeze when connecting to the MinIO console. The Safari browser is much more reliable. This problem appears to be caused by some features which are not properly handled by these browsers.","title":"Troubleshooting"},{"location":"wxd-troubleshooting/#troubleshooting-watsonxdata","text":"Although we have tried to make the lab as error-free as possible, occasionally things will go wrong.

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access. With the standalone software, users can be added within the console\u2019s Access control page. In the Developer Edition, users can be added using a command line tool. Credits: Portions of text found in this section were copied from Kelly Schlamb's watsonx.data L3 course. User Administration This lab is using the Developer edition of the watsonx.data software, which means that the Access control panel is not available. In order to manage users, the user-mgmt command will need to be used. The user-mgmt command is found in the /root/ibm-lh-dev/bin directory. Examples of using the command are found below. Add a User The syntax for adding a user is: ./user-mgmt add-user <username> [ User | Admin ] <password> The values are: username - The name of the user [User|Admin] - The type of user. Note that the type of user is case-sensitive! password - The password for the user. The following command will add the user watsonx with a password of watsonx.data . This will be a standard user with no privileges. The first step is to make sure you are connected as the root user in watsonx.data server and have switched to the proper directory. sudo su - cd /root/ibm-lh-dev/bin The next command will add a new user to the system. ./user-mgmt add-user watsonx User watsonx.data Change a User's Password The syntax for changing a password is: ./user-mgmt change-password <username> This command will require that the user enter the new password. You can issue the command and provide the new password at the prompt. The other way to simulate the enter command is to use the Linux yes function which repeats a value multiple times. The following command will change the password of watsonx to hellowatson . yes hellowatson | ./user-mgmt change-password watsonx Validate a User's Password You can validate a password by using the following command: ./user-mgmt test-user-cred <username> The username is the name of the user that you want to check the password for. This command will require that the user enter the existing password to check it. You can use the yes function (as described above) to simulate the enter command. The following command will check that we have changed the password of watsonx to hellowatson . yes hellowatson | ./user-mgmt test-user-cred watsonx Delete a User To delete a user, use the following command: ./user-mgmt delete-user <username> The error messages on group ownership can be safely ignored. The following command will remove our watsonx user. ./user-mgmt delete-user watsonx Roles and Policies In this section you will add a new user and provide them with privileges over the infrastructure and data. First start by adding a new user to the watsonx.data system. If you haven't already, make sure you are connected to the server as the root user and are in the /root/ibm-lh-dev/bin directory. Add user1 to the system with a password of password . ./user-mgmt add-user user1 User password Access Control To view what users are currently authorized to use the system, select the Access control icon found on the left side of the watsonx.data UI. A list of objects that make up the watsonx.data infrastructure are displayed. You can see that the objects are made up of: Engines Catalogs Buckets In a real-world scenario where a user will be querying data from a table, that user will need to be given a minimum of User access to an engine (to be able to run the query), User access for the catalog associated with the data (to be able to see the schema information associated with the table), and Reader access to the bucket associated with the data (to be able to read the data from object storage). Additionally, a policy has to be created to permit the user to access the table in question. Granting Access Select the presto-01 engine (highlighted in red above) to view the current users that have access to the engine. At this point, only the administrative user (ibmlhadmin) can use the Presto engine. Click on the Add Access button to add a new authorized user to the list. The role button has been selected in the dialog to show the role options of Admin, Manager, or User. An Admin user can grant any role to a user, while a Manager can only grant User privileges. For this lab, grant user1 \"user\" privileges and then press Add. Close the dialog by clicking on the [x] on the top right of the screen. Now user1 needs to be granted access to a catalog. In this case, the iceberg_data and hive_data catalogs are required for the Presto engine and are implicitly granted to the user. Click on the iceberg_data line to confirm that this is the case. You should see that user1 has already been granted access to the catalog. If your version of watsonx.data Developer Edition does not have access granted to user1 , add it manually using the same steps as for engine access. Close the dialog to return to the Access control screen. The final step is to grant access to the underlying buckets. Because user was implicitly granted access to the iceberg_data and hive_data catalogs, the underlying buckets iceberg-bucket and hive-bucket were also added to their access list. Click on iceberg-bucket to view the access control. Again, if user1 does not have access to the bucket, add access using the same steps as adding engine access. When done viewing the screen, close the dialog to return to the Access control dialog. Policies After access has been granted to engines, catalogs, and buckets, the final step is to create a policy to grant access to tables. Click on the Policy tab to display the current policies in place (there should be none). The Add Policy button is highlighted on the far right side of the screen. Pressing the button will display the new Access Control Policy dialog. Fill in the following information: Policy name: selectflights Description: blank Policy status: active You can always activate a policy after you have created it. Click Next. Here we need to select which schemas that the user will be able to access. For this example, select the ontime schema. After selecting the schema, a set of tables associated with the schema will be listed. You can choose which tables can be searched. If you choose an individual table, you can restrict which columns can be searched. Select the ontime table and then select the following columns (you will need to scroll down the page): flightdate reporting_airline flight_number_reporting_airline originairportid destairportid Once you have selected the columns, press the Next button to display the Rules dialog. The Rules dialog allows you to fine-tune what actions can be done by a user against the data. Press the Add Rule button to display the Add Rule dialog. Rules can be used to Allow actions or to Deny actions. In our example, we want to allow user1 to SELECT data from the data, but with no other options. Note : In production versions of watsonx.data, you can provide access to a group which makes it simpler to create a set of rules that apply to a group and then add a user to a group. That way a user will inherit the rules that were applied to the group rather than having to create rules for that individual. The developer edition displays GROUP as an option, but it is not implemented. Once the fields are filled in, press the Add button. You can continue to add additional rules to the list. Since we only want the one rule, select the Review button. Once you have confirmed that the data objects and rules look correct, press the Save button. The selectflights policy is now in place and is actively enforced. Before testing the policy enforcement, use the SQL icon on the left side to navigate to the hive_data catalog and view the schemas that are associated with it. Expand the ontime schema to view the tables and the columns that are available in the ontime table. When you connect as user1 , you will be able to compare what objects can be accessed from that userid. Testing Policy Enforcement To test whether the rules are enforced, you will need to log out of the current watsonx.data UI session. At the top of the Access Control screen, you will see the user icon on the top right. Clicking on the icon will display the logout dialog. Log out to the main watsonx.data UI screen. You will be prompted to confirm log out. Once back to the main log in panel, enter user and password into the dialog. Your watsonx.data UI should now display user1 . Navigate to the SQL icon and then select hive_data -> ontime -> ontime . You should notice that user1 was restricted to seeing only the ontime schema in the hive_data catalog. In addition, the user was restricted to accessing one of the tables ( ontime ) and 5 columns. Attempting to run a SELECT statement against all the data will result in a policy error. Correcting the SQL to include only permitted columns results in an answer set. The policy rules have been enforced for user1 , preventing them from viewing any other schemas or tables in the system. In addition, the SQL that they could execute was restricted to specific columns in the table. Before moving onto any other sections, make sure to log out as user1 and reconnect as the ibmlhadmin user.","title":"User Administration and Roles"},{"location":"wxd-useradmin/#watsonxdata-user-administration-and-roles","text":"Security and access control within watsonx.data are based on roles.

If you are attempting to connect to the watsonx.data system from outside the virtual machine, you will need to run the following commands to fix the self-signed certificate. Step 1: Connect to the Server Use the SSH port to connect into the server and make sure that you become the root user. sudo su - Step 2: Update the Certificate We need to update the certificate by using a utility in the developer toolbox. Start the toolbox code by switching to the bin directory and issuing the following command. cd /root/ibm-lh-dev/bin ./dev-sandbox Once inside the development container, you will need to update the program that generates the certificates. Note : The certificate should cover all TechZone locations. If for some reason your TechZone server does not match the pattern *.services.cloud.techzone.ibm.com , update it in the command below. sed -i '/DNS.14.*/a DNS.15 = watsonxdata' /scripts/gen_certs.sh sed -i '/DNS.15.*/a DNS.16 = watsonxdata.gym.lan' /scripts/gen_certs.sh sed -i '/DNS.16.*/a DNS.17 = *.services.cloud.techzone.ibm.com' /scripts/gen_certs.sh ./scripts/gen_certs.sh Once the script completes, exit the toolkit. exit Step 3: Stop and Restart the System The certificates need to be replaced in all the running containers. You must stop and restart them. You must include the diagnostic flag or else the system will not work properly. The startup will take some time to complete. The Postgres pod will display some warning messages which can be safely ignored. ./stop.sh export LH_RUN_MODE = diag ./start.sh Step 4: Generate Custom Certificate The first step is to copy the new certificates to the central /certs directory use by this image. docker cp ibm-lh-presto:/mnt/infra/tls/lh-ssl-ts.jks /certs/lh-ssl-ts.jks docker cp ibm-lh-presto:/mnt/infra/tls/cert.crt /certs/lh-ssl-ts.crt Next we need to generate the certificate file that is used by a number of the examples in the lab instructions. rm -f presto.crt echo QUIT | openssl s_client -showcerts -connect 127 .0.0.1:8443 | awk '/-----BEGIN CERTIFICATE-----/ {p=1}; p; /-----END CERTIFICATE-----/ {p=0}' > presto.crt You can print the certificate if you need it for connections from CP4D. cat presto.crt Step 5: Generate Java Keystore File The next step will create the Java Keystore file.

Usually this location is your workstation, but it could be another service like CP4D. To extract the certificate to your local file system, use the following command in a terminal window. Replace the port and regions.techzone-server.com with the SSH values found in the TechZone reservation. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Credentials notebook. There you will find links to the certificates. Watsonx.data Presto Access When connecting to the Presto engine, choose the PrestoDB driver. Presto Internal Access For local access the following credentials are used: Hostname: localhost Port: 8443 Username: ibmlhadmin Password: password Database: tpch In addition, you need to set the following driver properties: SSL True SSLTrustStorePath /certs/presto-key.jks SSLTrustStorePassword watsonx.data Presto External Access The watsonx.data Presto database requires that the certificate be extracted from the image. See the section above on Connection Certificate for more details. In the following settings, remember to update the Hostname and Port to the values provided in your TechZone reservation. The database connection settings are: Hostname: region.services.cloud.techzone.ibm.com Port: port Username: ibmlhadmin Password: password Database: tpch In addition, you need to set the following driver properties: SSL True SSLTrustStorePath /mydownload/presto-key.jks SSLTrustStorePassword watsonx.data Note : The /mydownload/presto-key.jks value needs to be replaced with the location that you copied the key in the earlier step. Db2 Access When connecting to the Db2 engine, select the Db2 LUW driver. Db2 Internal Access The Db2 server can be accessed on port 50000 inside the virtual machine using the following credentials: Hostname - watsonxdata Port - 50000 Username - db2inst1 Password - db2inst1 Database - gosales SSL - off Db2 External Access When accessing the database outside the virtual machine, you must change the host to region.services.cloud.techzone.ibm.com and the port number based on your TechZone reservation. All the other settings remain the same. Hostname - region.services.cloud.techzone.ibm.com Port - port Username - db2inst1 Password - db2inst1 Database - gosales SSL - off PostgreSQL Access When connecting to the PostgreSQL engine, select the PostgreSQL driver. In order to connect to the PostgreSQL system, you will need to extract the admin password using the following command when connected to the watsonx.data system. cat /certs/passwords You can also retrieve the credentials by opening up the Credentials notebook in the Jupyter notebook service. PostgreSQL Internal Access When accessing the PostgreSQL database in the system, use the following settings. Hostname \u2013 ibm-lh-postgres Port \u2013 5432 Username \u2013 admin Password \u2013 The value that was extracted in the earlier step Database \u2013 gosales PostgreSQL External Access The following credentials are used for remote access.

MySQL External Access The following credentials are used for remote access. Hostname: regions.techzone-server.com Port: port Username: root Password - password Database name: gosalesdw You must set the allowPublicKeyRetrieval to True for the connection to work with dBeaver (see above). Adding a Database to watsonx.data When adding a database engine to the watsonx.data system, make sure to change the database display name since that needs to be unique. For instance, when you add gosales database from Db2 to the system, the display name could be gosales as well. However, if you now add the PostgreSQL database to the system, the display name cannot be the same. You may want to differentiate databases with the same name by prefixing them with the database type. For instance, the gosales database could be shown as db2_gosales or pg_gosales so that you keep the names distinct. Once a database has been added, make sure to wait for a few moments before attempting to access the database. The Presto server takes a few moments to start up. To make sure that it is running, run the check_presto command in a terminal window and wait until it says the service is ready. When attempting to view the contents of a new database, the process may take a few minutes to complete. Refresh the browser window if you haven't seen any changes to the display. Accessing watsonx.data via Python In order to access the watsonx.data database (Presto), you will need to install the Presto client using the following command on your local machine. pip3 install presto-python-client Once the installation is complete, extract the certificate from the watsonx.data server that we will use in the connection. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Certificate notebook. Python and Jupyter Connection Code Your Python or Jupyter notebook code will need to import the prestodb library and then connect to watsonx.data using the connect call. import prestodb conn = prestodb.dbapi.connect( host='watsonxdata', port=8443, user='ibmlhadmin', catalog='tpch', schema='tiny', http_scheme='https', auth=prestodb.auth.BasicAuthentication(\"ibmlhadmin\", \"password\") ) conn._http_session.verify = '/certs/lh-ssl-ts.crt' cur = conn.cursor() In the above connection string, you will need to replace the following values: host - watsonxdata when connecting to the image externally, and ibm-lh-presto-svc when connecting internally catalog - What is the name of the catalog that we are accessing schema - The schema inside the catalog that will be used You also need to update the conn._http_session.verify value with the location where you downloaded the lh-ssl-ts.crt file. For internal connections, this value will be /certs/lh-ssl-ts.crt . Once connected, you can run an SQL statement and return the results. cur.execute(\"SELECT * FROM tpch.tiny.customer\") rows = cur.fetchall() The rows variable contains the answer set from the select statement. You can manipulate the row variable to view the results. rows[0] [1, 'Customer#000000001', 'IVhzIApeRb ot,c,E', 15, '25-989-741-2988', 711.56, 'BUILDING', 'to the even, regular platelets. regular, ironic epitaphs nag e'] The PrestoDB driver supports the DBAPI spec. For more details on the use of the DBAPI interface, please refer to https://peps.python.org/pep-0249/ . For instance, if you want to find the description of the columns returned, you would use the description function. cur.description [('custkey', 'bigint', None, None, None, None, None), ('name', 'varchar(25)', None, None, None, None, None), ('address', 'varchar(40)', None, None, None, None, None), ('nationkey', 'bigint', None, None, None, None, None), ('phone', 'varchar(15)', None, None, None, None, None), ('acctbal', 'double', None, None, None, None, None), ('mktsegment', 'varchar(10)', None, None, None, None, None), ('comment', 'varchar(117)', None, None, None, None, None)] Accessing watsonx.data via Pandas Dataframes The following code is required for accessing watsonx.data in Jupyter notebooks. Run the following code inside a notebook code cell. %pip install ipython-sql==0.4.1 %pip install sqlalchemy==1.4.46 %pip install sqlalchemy==1.4.46 \"pyhive[presto]\" The notebook may need a restart of the kernel to pick up the changes to the driver. If you are running in a Jupyter Lab environment, you can use the most current versions of the drivers. %pip install ipython-sql %pip install sqlalchemy %pip install sqlalchemy \"pyhive[presto]\" Once the drivers have been loaded, you will need to extract the certificate from the watsonx.data server that we will use in the connection. scp -P port watsonx@region.services.cloud.techzone.ibm.com:/certs/presto-key.jks /Users/myname/Downloads Change the target directory to a location that you can remember! You can also download the certificate by using the Jupyter Notebook link and opening the Certificate notebook. In your Jupyter notebook, you will need to import a number of libraries. import pandas as pd import sqlalchemy from sqlalchemy import create_engine Create a notebook cell which will contain all the credentials that are required to connect. Change the catalog , schema and certfile to your values. userid = \"ibmlhadmin\" password = \"password\" hostname = \"watsonxdata\" port = \"8443\" catalog = \"tpch\" schema = \"tiny\" certfile = \"/certs/lh-ssl-ts.crt\" connect_args={ 'protocol': 'https', 'requests_kwargs': {'verify': f'{certfile}'} } In the above settings, you will need to replace the following values: hostname - region.services.cloud.techzone.ibm.com when connecting to the image externally, and ibm-lh-presto-svc when connecting internally catalog - What is the name of the catalog that we are accessing schema - The schema inside the catalog that will be used You also need to update the certfile value with the location where you downloaded the lh-ssl-ts.crt file. For internal connections, this value will be /certs/lh-ssl-ts.crt . To create a connection to the database, use the following syntax. engine = create_engine( f\"presto://{userid}:{password}@{hostname}:{port}/{catalog}/{schema}\", connect_args=connect_args ) Now that you have established a connection, you can use the Pandas read_sql_query function to execute a SELECT statement against the database. mypresto = pd.read_sql_query('SELECT * from tpch.tiny.customer',engine) The variable mypresto contains the dataframe generated from the SELECT statement. mypresto You can use the features of Pandas to generate plots of the data in your notebook. First make sure you have matplotlib installed. %pip install matplotlib The following query will compute the total account balance across all nation key values. sumbynation = pd.read_sql_query('SELECT \"nationkey\", sum(\"acctbal\") from tpch.tiny.customer group by \"nationkey\" order by 2',engine) Finally, we plot the results. df.plot(kind=\"bar\", x=\"FirstName\", y=\"LastName\") plt.show() Adding a Service The watsonx.data developer edition includes two open ports which can be used to externalize a service that you create in the image. For instance, you may choose to create a MongoDB or MSSQL container using Docker and want to access this service from your own dBeaver or Mongo tooling. Since port numbers vary between different databases, the watsonx.data system provides two port numbers that can be used by your service. Open Port 1 - Server: region.services.cloud.techzone.ibm.com: Port: 12345 Open Port 2 - Server: region.services.cloud.techzone.ibm.com: Port: 23456 The internal port numbers are 10000 (Port 1) and 10001 (Port 2). The following steps are required to use these ports with your service. Open the local Firewall (Version 1.1.0 Only) Ports 10000/1 are not open by default in the 1.1.0 image. For release 1.1.1, you can skip this step. You must explicitly open ports 10000/1 with the firewall-cmd command. In a command line shell, as the root user, enter the following commands: sudo su - firewall-cmd --add-port={10000/tcp,10001/tcp} --zone=public --permanent firewall-cmd --reload You can use the following command to check that the ports are now open. firewall-cmd --list-ports Create your Service When creating your service, make sure to map the internal Docker port to either port 10000 or 10001. If you cannot remap the port, see the section on port redirection. For instance, the following command will start Microsoft SQLServer in Docker by mapping the host port 10000 to the SQLServer port of 1433 to 10000 ( -p 10000:1443 ). docker run -e \"ACCEPT_EULA=Y\" -e \"MSSQL_SA_PASSWORD=Passw0rd12345678!\" \\ -p 10000:1433 --name mssql-server --hostname mssql-server \\ -d mcr.microsoft.com/mssql/server:2019-latest You can check the port mapping with the following command. docker container ls --format \"table {{.ID}}\\t{{.Names}}\\t{{.Ports}}\" -a | grep mssql-server When creating a connection to this database using an external tool, make sure to use the port number supplied in the reservation details (Open Port 1 is for port 10000 and Open Port 2 is for port 10001). Port Redirection If you already have an existing service mapped to a different port, you can use port redirection to use either port 10000 or 10001. For instance, assume that the previous creation of the SQLServer database used port 1433. docker run -e \"ACCEPT_EULA=Y\" -e \"MSSQL_SA_PASSWORD=Passw0rd12345678!\" \\ -p 1433:1433 --name mssql-server --hostname mssql-server \\ -d mcr.microsoft.com/mssql/server:2019-latest Once the service is up and running, you can redirect the traffic on port 10000/1 to the port of your docker service. firewall-cmd --add-forward-port=port=10000:proto=tcp:toport=1433 --permanent --zone=public firewall-cmd --reload If you need to remove the redirection, use the following command. firewall-cmd --remove-forward-port=port=10000:proto=tcp:toport=1433:toaddr= --permanent --zone=public firewall-cmd --reload Accessing your Service When referring to your service from an external location, always use the port numbers that are provided for Open Port 1 or 2. Open Port 1 - Server: region.services.cloud.techzone.ibm.com: Port: 12345 Open Port 2 - Server: region.services.cloud.techzone.ibm.com: Port: 23456 Your server will be region.services.cloud.techzone.ibm.com and the port number will be either of the two port numbers provided. Remember that this port number will need to be opened in the server and a Docker mapping to the open port or a firewall port redirection will be required.","title":"Database Connections"},{"location":"wxd-connections/#database-connections","text":"There are three database systems that can be accessed inside and outside the virtual machine environment: watsonx.data Presto, Db2 LUW, MySQL and PostgreSQL.

Check out the following websites for a variety of public data sets that you can use. Awesome Public Datasets Kaggle Datasets US Data.Gov UCI Machine Learning Repository US Fuel Economy Note : These sites have not been checked for license restrictions on the use of the data. You are responsible for checking that the data can be used without any licensing requirements. Loading your own data You can use a browser or link to an external file repository (i.e., Box) and download data directly to your workstation. Data can be CSV, Parquet, JSON, or TXT formats. Once the data is on your workstation, use the following steps. Note : You cannot import customer data nor any data that has restrictions associated with its use. Any use of private data is in violation of the terms and conditions of using this image. The first step is to connect to MinIO. Extract the MinIO credentials by using the passwords command: passwords Open your browser and navigate to the MinIO console. Login with object store credentials found above (These will be different for your system). You should see the current buckets in MinIO. If you don't see the buckets, click on Object Browser on the left-hand side panel. Select hive-bucket from the list of buckets. You may see other directories in this list than what is shown above. You will need to create a new path for your data set. Create a new directory name for your data (fuel_economy was used for this example). MinIO will display an empty directory and suggest you load something into it. Use the Upload button on the far right side to point to your dataset on your local machine. In this example, we are using a CSV file for the 2013 fuel economy estimates for automobiles sold in the US. You may need to rename you datasets to eliminate blanks and any other special characters other than \" _ \" or \" - \". The display will show the progress of the upload into the bucket. You may need to refresh your browser to see the file in the bucket. Now that the data has been loaded into a bucket, you can catalog it in the watsonx.data UI. If you created a new bucket for this data set, you will need to register it first in the watsonx.data UI. Instructions for how to do this are found in the Working with Object Store Buckets section. Start by navigating to the watsonx.data UI and look at the Infrastructure manager. Find the bucket where you upload your data set into and note the catalog name that it is associated with. Here we can see that the hive-bucket bucket is associated with the hive_data catalog. In the watsonx.data UI, select the Query workspace (SQL) icon. You will need to create a schema that links to this data set. The format of the command is shown below. DROP SCHEMA catalog.schema_name; CREATE SCHEMA catalog.schema_name WITH ( location = 's3a://your-bucket/data_directory' ); You will need to change the following values: catalog - The catalog that the bucket you are using is associated with schema_name - A schema name to associate your tables with data_directory - The directory in which your file is located your_bucket - The bucket the data physically resides in For the fuel economy example, using mpg as the schema, the SQL would be: DROP SCHEMA hive_data.mpg; CREATE SCHEMA hive_data.mpg WITH ( location = 's3a://hive-bucket/fuel_economy' ); Run this SQL against the Presto engine: The DROP command may fail if the schema doesn't exist, but the CREATE should work. The next step is to define what the table looks like for watsonx.data to be able to query it. The syntax of the CREATE TABLE statement is similar to: CREATE TABLE catalog.schema.tablename ( \"column_name\" \"type\", ... ) WITH ( format = 'CSV', csv_separator = ',', external_location = 's3a://your_bucket/data_directory'); You will need to create a table definition for your CSV file in order to catalog it in watsonx.data. Note that the only data type that is permitted for CSV columns is varchar . This is a restriction of the current driver. Plans are to update it to include other data types over time. If your data set does not include a header row (a row that defines the column names), you will need to create the table definition manually. If the data set does contain a header record, you can use the following Python code to generate a CREATE TABLE statement. You will need to make sure that pandas is available. python3 -m pip install pandas --user Next run the python3 command in the shell to run an interactive Python session. python3 Place the following code into your Python window. def showcsv(catalog, schema, tablename, bucket, directory, csv_in): import pandas as pd df = pd.read_csv(csv_in,na_values=\"-\") df = df.fillna(0) column_headers = list(df.columns.values) print(\"\") print(f\"DROP TABLE IF EXISTS {catalog}.{schema}.{tablename};\") print(f\"CREATE TABLE {catalog}.{schema}.{tablename}\") print(\" (\") comma = \"\" end = \"\" for header in column_headers: print(f\"{comma}\",end=end) comma = \",\" end = \"\\n\" print(f' \"{header}\" varchar',end=\"\") print(f\" )\") print(f\"WITH (\") print(f\" format = 'CSV',\") print(f\" csv_separator = ',',\") print(f\" external_location = 's3a://{bucket}/{directory}'\") print(f\" );\") print(\"\") def makesql(): catalog = input(\"Catalog : \") schema = input(\"Schema : \") table = input(\"Table : \") bucket = input(\"Bucket : \") dir = input(\"Directory : \") csv = input(\"CSV File : \") showcsv(catalog,schema,table,bucket,dir,csv) Gather the following information on your dataset: catalog - The catalog the schema and table are created under ( hive_data ) schema - The schema name that you created to hold your table ( mpg ) table name - The name of the table ( fuel_economy ) bucket - Where the data is located ( hive-bucket ) directory - What directory contains your data ( fuel_economy ) csv_in - The location on your local machine where the csv file is Once you have gathered that, run the following command in your Python window and answer the prompts. makesql() >>> makesql() Catalog : hive_data Schema : mpg Table : fueleconomy Bucket : hive-bucket Directory : fuel_economy CSV File : ~/Downloads/fuel_economy_2013.csv DROP TABLE IF EXISTS hive_data.mpg.fueleconomy; CREATE TABLE hive_data.mpg.fueleconomy ( \"MODEL_YEAR\" varchar, \"MFR_NAME\" varchar, \"DIVISION\" varchar, \"CARLINE\" varchar, \"ENG_DISPL\" varchar, \"CYL\" varchar, \"TRANS_IN_FE_GUIDE\" varchar, \"CITY_FE_CONVENTIONAL_FUEL\" varchar, \"HWY_FE_CONVENTIONAL_FUEL\" varchar, \"COMB_FE_CONVENTIONAL_FUEL\" varchar, \"AIR_ASPIRATION_DESC\" varchar, \"TRANS_DESC\" varchar, \"GEARS\" varchar, \"DRIVE_DESC\" varchar, \"FUEL_UNIT_CONVENTIONAL_FUEL\" varchar, \"FUEL_UNIT_DESC_CONVENTIONAL_FUEL\" varchar, \"ANNUAL_FUEL_COST_CONVENTIONAL\" varchar, \"FUEL_METERING_SYS_DESC\" varchar ) WITH ( format = 'CSV', csv_separator = ',', external_location = 's3a://hive-bucket/fuel_economy' ); Cut and paste the output from the command into the watsonx.data Data Explorer window to create the file.

It is fast, lightweight, intuitive, and loaded with options that make it easy for users of all skill sets to explore and visualize their data, from simple pie charts to highly detailed geospatial charts. Application Programming Interface (API)**: Application Programming Interface (API) is a programmatic interface for executing functions of an application in an automated or manual fashion without using a CLI or User Interface. Buckets : Buckets are the basic containers that hold your data. Everything that you store in Cloud Storage must be contained in a bucket. You can use buckets to organize your data and control access to your data, but unlike directories and folders, you cannot nest buckets. Catalog : This term may have many meanings depending on context. Review below: Service Catalog - A service catalog is a comprehensive list of cloud computing services that an organization offers its customers. The catalog is the only portion of the company's service portfolio that is published and provided to customers as a support to the sale or delivery of offered services. Data Catalog - A collection of business information describing the available datasets within an organization. Metastore Catalog - A collection of technical and operational metadata allowing a query engine to overlay a virtual table on a collection of discrete data files. Connector Catalog - The named representation of a connector within the virtual warehouse of a presto instance. Command Line Interface (CLI) : A command-line interface (CLI) is a text-based user interface (UI) used to run programs, manage computer files and interact with the computer. dBeaver : DBeaver is a SQL client software application and a database administration tool. For relational databases it uses the JDBC application programming interface to interact with databases via a JDBC driver. For other databases it uses proprietary database drivers. Federation : A federated database is a system in which several databases appear to function as a single entity. Each component database in the system is completely self-sustained and functional. When an application queries the federated database, the system figures out which of its component databases contains the data being requested and passes the request to it. Federated databases can be thought of as database virtualization in much the same way that storage virtualization makes several drives appear as one. MinIO : MinIO is a high-performance, S3 compatible object store. It is built for large scale AI/ML, data lake and database workloads. It runs on-prem and on any cloud (public or private) and from the data center to the edge. MinIO is software-defined and open source under GNU AGPL v3. Object Storage : Object storage is a data storage architecture for storing unstructured data, which sections data into units\u2014objects\u2014and stores them in a structurally flat data environment. Each object includes the data, metadata, and a unique identifier that applications can use for easy access and retrieval. Presto : Presto is a distributed database query engine (written in Java) that uses the SQL query language. Its architecture allows users to query data sources such as Hadoop, Cassandra, Kafka, AWS S3, Alluxio, MySQL, MongoDB and Teradata, and allows use of multiple data sources within a query. Presto is community-driven open-source software released under the Apache License. Presto's architecture is very similar to other database management systems using cluster computing, sometimes called massively parallel processing (MPP). SPARK : Apache Spark is an open-source unified analytics engine for large-scale data processing. Spark provides an interface for programming clusters with implicit data parallelism and fault tolerance. Spark can be used with watsonx.data but is not included in the watsonx.data environment image provided. TechZone (IBM Technology Zone) : IBM Technology Zone is the platform where the developer edition of watsonx.data with the sample data sets has been provisioned. Generally, it allows Go To Market teams and Business Partners to easily build technical 'Show Me' live environments, POTs, prototypes, and MVPs, which can then be customized and shared with peers and customers to experience IBM Technology.

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access. With the standalone software, users can be added within the console\u2019s Access control page. In the Developer Edition, users can be added using a command line tool. Click on the Access Control icon on the left side of the screen The Access Control panel is divided into Infrastructure and Policies. The initial screen displays the objects that are considered part of the Infrastructure. A user must be granted access to the infrastructure (i.e. Presto engine) in order for them to run queries against any of the schemas in the database. Click on the Policies Tab Your system should not contain any policies at this time. Roles and Policies In this section you will add a new user and provide them with privileges over the infrastructure and data. First start by adding a new user to the watsonx.data system. This lab is using the Developer edition of the watsonx.data software, which means that the Access control panel does not provide a UI for adding users. In order to manage users, the user-mgmt command will need to be used. The user-mgmt command is normally run from a command line in the server. This server includes a user called watsonx with a password of watsonx.data . If you want to add additional users, see the User Administration section at the end of this lab. Access Control To view what users are currently authorized to use the system, select the Access control icon found on the left side of the watsonx.data UI. Click on the Access Control icon on the left side of the screen A list of objects that make up the watsonx.data infrastructure are displayed. You can see that the objects are made up of: Engines Catalogs Buckets In a real-world scenario where a user will be querying data from a table, that user will need to be given a minimum of User access to an engine (to be able to run the query), User access for the catalog associated with the data (to be able to see the schema information associated with the table), and Reader access to the bucket associated with the data (to be able to read the data from object storage). Additionally, a policy has to be created to permit the user to access the table in question. Granting Access Select the presto-01 engine (highlighted in red above) to view the current users that have access to the engine At this point, only the administrative user (ibmlhadmin) can use the Presto engine. Click on the Add Access button to add a new authorized user to the list If you do not see the watsonx userid, or the dropdown is blank, issue the following command in a terminal window. Once the user is added, refresh the browser window and then click on the Add Access button again. sudo /root/ibm-lh-dev/bin/user-mgmt add-user watsonx User watsonx.data The role button has been selected in the dialog to show the role options of Admin, Manager, or User. An Admin user can grant any role to a user, while a Manager can only grant User privileges. Grant watsonx \"user\" privileges and then press Add Close the dialog by clicking on the [x] on the top right of the screen The watsonx user needs to be granted access to a catalog. In this case, the iceberg_data and hive_data catalogs are required for the Presto engine and are implicitly granted to the user. Click on the iceberg_data line to confirm that watsonx has access You should see that watsonx has already been granted access to the catalog. Close the dialog to return to the Access control screen The final step is to grant access to the underlying buckets. Because watsonx was implicitly granted access to the iceberg_data and hive_data catalogs, the underlying buckets iceberg-bucket and hive-bucket were also added to their access list. Click on iceberg-bucket to view the access control Close the dialog to return to the Access control dialog Policies After access has been granted to engines, catalogs, and buckets, the final step is to create a policy to grant access to tables. Click on the Policy tab to display the current policies in place (there should be none) The Add Policy button is highlighted on the far right side of the screen. Press the Add Policy button to display the new Access Control Policy dialog Fill in the following fields with these values Policy name: selectflights Description: blank Policy status: active You can always activate a policy after you have created it. Click Next Here we need to select which catalog to use and then the schemas that the user will be able to access. Select hive_data catalog, and then the ontime schema If you do not see any values being populated on the screen, refresh the browser After selecting the schema, a set of tables associated with the schema will be listed. You can choose which tables can be searched. If you choose an individual table, you can restrict which columns can be searched. Select the ontime table and then select the following columns (you will need to scroll down the page) flightdate reporting_airline flight_number_reporting_airline originairportid destairportid Press the Next button when all columns are selected The Rules dialog allows you to fine-tune what actions can be done by a user against the data. Press the Add Rule button to display the Add Rule dialog Rules can be used to Allow actions or to Deny actions. Allow watsonx to SELECT data from the data, but with no other options Note : In production versions of watsonx.data, you can provide access to a group which makes it simpler to create a set of rules that apply to a group and then add a user to a group. That way a user will inherit the rules that were applied to the group rather than having to create rules for that individual. The developer edition displays GROUP as an option, but it is not implemented. Make sure to select watsonx as the user Press the Add button You can continue to add additional rules to the list. Since we only want the one rule, select the Review button. Press the Review button Confirm that the data objects and rules look correct then press the Create button The selectflights policy is now in place and is actively enforced. Press the Query Workspace Icon Before testing the policy enforcement, use the SQL icon on the left side to navigate to the hive_data catalog and view the schemas that are associated with it. Expand the ontime schema to view the tables and the columns that are available in the ontime table When you connect as watsonx , you will be able to compare what objects can be accessed from that userid. Testing Policy Enforcement To test whether the rules are enforced, you will need to log out of the current watsonx.data UI session. At the top of the Query workspace screen, you will see the user icon on the top right. Click on the user icon to display the logout dialog Log out to the main watsonx.data UI screen You will be prompted to confirm log out. The log in dialog should be displayed. Enter the credentials for the watsonx user and press Log in Username: watsonx Password: watsonx.data Your watsonx.data UI should now display watsonx . Note how you have less components in the Infrastructure summary. Navigate to the SQL icon and then select hive_data \u2192 ontime \u2192 ontime You should notice that watsonx was restricted to seeing only the ontime schema in the hive_data catalog. In addition, the user was restricted to accessing one of the tables ( ontime ) and 5 columns. Attempting to run a SELECT statement against all the data will result in a policy error. Enter this text into the SQL window and Run the code SELECT * FROM \"hive_data\".\"ontime\".\"ontime\" LIMIT 10; Correcting the SQL to include only permitted columns results in an answer set. Enter this text into the SQL window and Run the code SELECT flightdate, reporting_airline, flight_number_reporting_airline, originairportid, destairportid FROM \"hive_data\".\"ontime\".\"ontime\" LIMIT 10; The policy rules have been enforced for watsonx , preventing them from viewing any other schemas or tables in the system. In addition, the SQL that they could execute was restricted to specific columns in the table. Before moving onto any other sections, make sure to log out as watsonx and reconnect as the ibmlhadmin user. Click on the user icon to display the logout dialog Log out to the main watsonx.data UI screen You will be prompted to confirm log out. The log in dialog should be displayed. Enter the credentials for the ibmlhadmin user and press Log in Username: ibmlhadmin Password: password Your watsonx.data UI should now display ibmlhadmin . Summary In this section you learned how to add a user to watsonx.data (via a command) and control what objects they are allowed to access. In production versions of watsonx.data, the adding and removal of users is directly handled through the User Interface. User Administration Users can be added to the watsonx.data Developer Edition by using a command line tool called user-mgmt . The syntax of the command is: ./user-mgmt add-user [User | Admin] The values are: username - The name of the user [User|Admin] - The type of user. Note that the type of user is case-sensitive! password - The password for the user. For the purposes of this lab, we are going to use a Jupyter notebook that was specifically created for managing users. Find the URL in your reservation that reads Jupyter Notebook - Server: http://region.services.cloud.techzone.ibm.com:xxxx/notebooks/Table_of_Contents.ipynb and click on it The initial screen will request that you enter a password. The password is watsonx.data . Enter watsonx.data as the password Once you have authenticated, the Table of Contents is displayed. Click on the Arrow on the User Administration tile. The Administration notebook is displayed. A Jupyter notebook contains multiple \"cells\" which can contain a couple of different objects: Code - A cell that contains code that will run (usually Python) Markdown - A cell that contains text and formatting using a language called Markdown In this lab, we need to run code that is found in the notebook. You can tell which text is a code cell because of the [ ]: beside the cell and probably because it has some code in the cell! Before executing the contents of the cell, you must click on the cell (place focus on the cell). You can tell when the focus is on the code cell because it will be highlighted with a thin blue box. To \"execute\" the contents of the cell, you must either hit the run button icon \u25ba or Shift-Return on your keyboard. Modify any values and run the contents of the cell which contains the add-user command A message indicating that a user was successfully added will be displayed in the notebook.

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access. With the standalone software, users can be added within the console\u2019s Access control page. In the Developer Edition, users can be added using a command line tool. Click on the Access Control icon on the left side of the screen The Access Control panel is divided into Infrastructure and Policies.

In order to manage users, the user-mgmt command will need to be used. The user-mgmt command is normally run from a command line in the server.

Before starting, make sure you are in the Query Workspace by clicking this icon on the left side For the analytic workloads, you are going to create a new schema in the iceberg_data catalog. The next statement will create the workshop schema in the existing iceberg-bucket . Create the workshop schema in the iceberg_data catalog CREATE SCHEMA IF NOT EXISTS iceberg_data.workshop with (location='s3a://iceberg-bucket/'); This SQL will create a new Apache Iceberg table using existing data in the sample Customer table as part of the TPCH catalog schema called TINY. Create the workshop customer table create table iceberg_data.workshop.customer as select * from tpch.tiny.customer; Let us start with some simple examples of running queries and analyzing the execution. Run a simple scan query which selects customer names and market segment use iceberg_data.workshop; select name, mktsegment from customer limit 3; To understand the query execution plan we use the explain statement. Run an explain against the previous statement use iceberg_data.workshop; explain select name, mktsegment from customer; What you see above is the hierarchy of logical operations to execute the query. It is very difficult to read since the information is found on one line. One option is to export the data and view the results in a spreadsheet. Explain the query and focus on IO operations use iceberg_data.workshop; explain (type io) select name, mktsegment from customer; Explain physical execution plan for the query. Explain physical execution plan for the query use iceberg_data.workshop; explain (type distributed) select name, mktsegment from customer; A fragment represents a stage of the distributed plan. The Presto scheduler schedules the execution by each stage, and stages can be run on separate instances. Rather than executing these explain queries, the SQL interface provides an explain button beside the Run button. Enter the following query into the SQL window and press the Explain button select name, mktsegment from iceberg_data.workshop.customer Click on the TableScan operator The panel on the right side provides information about the work the engine will do to retrieve the data. The Presto optimizer estimates that 1500 rows will be retrieved and take approximately 16000 cpu units. Close the explain window Another way of viewing the explain information is to run the query and then review the Query history. Run the query that is currently in the SQL window Once the query completes, switch to the Query history screen. Click on the Query History icon on the left side of the screen Refresh the browser to update the Query history Once you have refreshed the screen, look for your query in the list. It should be near the top. Click on the kebab \u22ee icon and select View Execution Plan You will see all the explain output that you created with the earlier SQL statements. Close the explain output by pressing the [x] on the screen Creating a Table with User-defined Partitions Before starting, make sure you are in the Query Workspace by clicking this icon on the left side Tables can be partitioned in watsonx.data. This SQL will create a partitioned table, based on column mktsegment with data copied from the TPCH.TINY.CUSTOMER table. Create a partitioned table create table iceberg_data.workshop.part_customer with (partitioning = array['mktsegment']) as select * from tpch.tiny.customer; The new table part_customer will be created in the iceberg_bucket with multiple files corresponding to the partitioning. We are going to use the Infrastructure manager to view the file structure. Click on the Infrastructure icon on the left side of the screen Find the iceberg-bucket in the Infrastructure diagram. Click on the iceberg-bucket Click on Objects \u2192 part_customer \u2192 data The partitioning = array['mktsegment'] clause in the create table statement resulted in 5 different files being created, each with data specific to that segment. By partitioning the table this way, the Presto engine is able to optimize queries by only scanning partitions that match your SQL predicates. Close the current window [x] and then return to the Query Workspace by clicking this icon on the left side Now that have created a partitioned table, we will execute an SQL statement that will make use of this fact. Run a query against the partitioned table select * from iceberg_data.\"workshop\".part_customer where mktsegment='MACHINERY'; Due to the partitioning of this table by mktsegment , it will completely skip scanning a large percentage of the objects in the object store. Press the explain keyword in the SQL window to view the execution plan and then select the ScanFilter You should see that the optimizer expected to read only 288 rows when running this query. This is due to the table being partitioned and scans only needing to be run against one of the partitions. Close the explain window Joins and Aggregations This section will create an orders table to test joins and aggregations. Create the Orders Table create table iceberg_data.workshop.orders as select * from tpch.tiny.orders; The following SQL uses a windowing function to compute a result set. SQL with a Windowing function SELECT orderkey, clerk, totalprice, rank() OVER (PARTITION BY clerk ORDER BY totalprice DESC) AS rnk FROM iceberg_data.workshop.orders ORDER BY clerk, rnk; Prepared statements Presto provides a feature for preparing statements for repeated execution. Using this method will reduce the overhead of optimizing the statement every time you run it. Save a query as a prepared statement prepare customer_by_segment from select * from iceberg_data.workshop.customer where mktsegment=?; Once the statement has been prepared, you can execute the statement by supplying it with some parameters. In this example we are combining the two statements because the session context is not shared between SQL executions.

Before describing the contents of the UI, some explanation of the watsonx.data objects are necessary. Watsonx.data is based on open-source Presto DB, a distributed query engine that enables querying data stored in open file formats using open table formats for optimization and performance. There are four types of objects that are commonly referred to in the Presto DB environment: Engine \u2013 Each watsonx.data installation has at least one Presto DB engine which is used for querying the data. An installation can have more than one Presto engine to improve performance, isolate workloads, or test different versions. Additional engines can include Apache Spark, which provides capabilities for reading and transforming many types of data. Catalogs \u2013 Catalogs contain information about tables, files, and objects that are found in databases or file systems. Catalogs can be specific to the type of object being manipulated (Apache Hive, Apache Iceberg). Buckets \u2013 Buckets refer to Cloud Object Storage (MinIO, AWS S3, IBM COS, etc...) that contain the files and objects that you will catalog and eventually query with an engine. Database \u2013 These represent 3rd party databases that are used to query tables that are in a vendor\u2019s proprietary format (Oracle, Db2, Netezza, etc...). Services - Services refer to additional components in watsonx.data (like Milvus) which provide specific features that are not found in the watsonx.data engine itself. There are two built-in catalogs provided with watsonx.data: Hive_data \u2013 This catalog contains references to objects that are immutable. These are objects such as CSV (comma-separated values), Text, JSON, and Apache Parquet files which are read-only. Iceberg_data \u2013 This catalog contains references to tables that are in Apache Iceberg format. These tables are optimized for space usage and query performance and can be updated.

Infrastructure Manager UI The Infrastructure manager page opens with a graphical canvas view of the different infrastructure components currently defined in this watsonx.data environment. Click on the Infrastructure icon on the left side of the screen The Infrastructure manager provides a helpful visualization of the current system. These components are: Engines (blue layer) \u2013 The query engines that will access the data. Catalogs (purple layer) \u2013 Catalogs contain metadata about the objects found in buckets or databases. Each catalog is associated with one or more engines. An engine can\u2019t access data in a bucket or a remote database unless the corresponding catalog is associated with the engine. Buckets (pink layer) \u2013 An object-store that contains data (i.e., MinIO, AWS S3, Cloud-Object Storage). Each bucket is associated with a catalog (with a 1:1 mapping). When a bucket is added to watsonx.data, a catalog is created for it at the same time, based on input from the user. Databases (blue layer) \u2013 Specialty Database engines.

To explore the contents of the hive_data catalog, click on the catalog icon. Click on the hive_data catalog icon Detailed information about the catalog is displayed on the screen. There are additional tabs at the top of the screen that provide information on the data objects that are cataloged and the access control for those objects. Click on the Data Objects tab The Data Objects tab provides detailed information on the contents of the catalog. This provides an easy way to explore the contents of the catalog. Click on the Access Control Tab The access control tab provides a list of users and groups that are authorized to access this bucket.

Exploring the Contents of a Bucket Hover your mouse over the hive_data bucket Instead of selecting the catalog, click on the hive-bucket at the bottom of the screen. Watsonx.data is a unified analytics repository, and it starts like most data management solutions with storage. The most pervasive storage solution in the marketplace is object store. There are several solutions in the marketplace providing low cost, unlimited scalability, extreme durability, and high throughput. The Developer edition of watsonx.data uses MinIO as an S3-complaint object store. The bucket hive-bucket resides in MinIO storage and is cataloged in watsonx.data. There are three additional buckets, iceberg-bucket used to store Iceberg tables, wxd-system used for control information, and wxd-milvus for Milvus vector database storage. There are three tabs in the bucket details pane: Details Objects Access Control Click on the Objects tab The objects tab provides a view into the physical files that are found in the bucket. There is a hierarchy of directories that make up the contents of the bucket. At the highest level we have the bucket itself, or hive-bucket in this example. The bucket contains a number of directories: gosales, ontime, taxi, and hive_sql. The display will indicate the number of directories or files that are found in the directory. This first level of directories map to the schema name. In the watsonx.data system, the schema ontime has the tables cataloged underneath the ontime directory. Click on the ontime directory The directories in this panel map to the table names. For instance, the directory aircraft is used to store the aircraft table. Click on the aircraft directory The physical file that is used to represent the aircraft types is found in this file. An iceberg table will include additional information containing versioning, statistics and partitioning of the table.

There are several solutions in the marketplace providing low cost, unlimited scalability, extreme durability, and high throughput. The Developer edition of watsonx.data uses MinIO as an S3-complaint object store. The bucket hive-bucket resides in MinIO storage and is cataloged in watsonx.data.

There are three tabs in the bucket details pane: Details Objects Access Control Click on the Objects tab The objects tab provides a view into the physical files that are found in the bucket. There is a hierarchy of directories that make up the contents of the bucket. At the highest level we have the bucket itself, or hive-bucket in this example. The bucket contains a number of directories: gosales, ontime, taxi, and hive_sql. The display will indicate the number of directories or files that are found in the directory. This first level of directories map to the schema name. In the watsonx.data system, the schema ontime has the tables cataloged underneath the ontime directory.

For example, there is usually an interactive command line interface (CLI) that lets users run SQL statements from a command terminal. Applications can use JDBC (Java Database Connectivity) to connect to the data store and run SQL statements. The watsonx.data user interface includes an SQL interface for building and running SQL statements. This is called the Query workspace. Users can write or copy in their own SQL statements, or they can use templates to assist in building new SQL statements. Click on the Query Workspace icon on the left side of the screen The Query workspace will have a similar layout to the Data Manager screen, where you can navigate through the catalogs associated with the selected engine. The SQL work area is found to the right of the catalog and table names. You can type, paste, or use saved workspaces to enter SQL (Structured Query Language) commands into this window. An SQL statement instructs the database engine what records to look for in one or more tables. The Query workspace provides several pre-built SQL statements that can be generated for tables already cataloged in the system. In the Data Manager lab, the Data sample tab was used to view a subset of the data in the airline_delay_cause table. This data can be generated in the Query Workspace window by using a prebuilt SQL generator.

Generate Select \u2013 An SQL statement that will return the contents of the table. Generate Alter \u2013 An SQL statement (DDL \u2013 Data Definition Language) used to alter characteristics of the table, like adding a column. Generate Drop \u2013 An SQL statement used to remove the object from the system. Select the Generate SELECT option The system has populated the SQL window with the catalog name, the schema and the table name. This SQL will retrieve all the columns of the table and limit the output to 10 rows (LIMIT 10). The Run on presto-01 button is highlighted at the far right of the SQL window. The button will reflect which engine watsonx.data will run your query on. There is a pulldown menu beside the button that provides an option to run the query to the point where your cursor is on the text, or from where your cursor is on the text. You can use these options to run portions of an SQL statement when you are debugging results. In this instance, you just want to run the query and display the results. Press the Run on presto-01 button and wait for the results to return Near the middle of the screen, you will see the statement that was executed, the run time, and the success or failure of the statement.

You can use these options to run portions of an SQL statement when you are debugging results. In this instance, you just want to run the query and display the results. Press the Run on presto-01 button and wait for the results to return Near the middle of the screen, you will see the statement that was executed, the run time, and the success or failure of the statement. The result set (if there is one) is displayed below the SQL statement. An export icon \u2913 is found on the far-right side of the result set. Clicking on the export icon will download the results as a CSV file on your workstation. Select the Details tab in the result set window This dialog provides more information on the execution of the SQL statement. If you want additional details on the query execution plan, you can press the Explain button beside the Run on presto-01 button. Press the Explain button in the SQL window The graph displays the steps the Presto engine took to compute the answer. You can click on any one of the boxes in the diagram to display the details of the step. The system will not show many details because the data is in a hive catalog and not optimized for retrieval. Close the Explain dialog by pressing the [x] If you find that you are running the same SQL repeatedly, you can save the SQL as a worksheet. The SQL window should still have your select statement that was generated to retrieve the first 10 rows of the table. The save button is found above the SQL.

The UI for Apache Kafka is a simple tool that makes your data flows observable, helps find and troubleshoot issues faster and deliver optimal performance. Its lightweight dashboard makes it easy to track key metrics of your Kafka clusters - Brokers, Topics, Partitions, Production, and Consumption. 1 Some of the key features: Multi-Cluster Management \u2014 monitor and manage all your clusters in one place Performance Monitoring with Metrics Dashboard \u2014 track key Kafka metrics with a lightweight dashboard View Kafka Brokers \u2014 view topic and partition assignments, controller status View Kafka Topics \u2014 view partition count, replication status, and custom configuration View Consumer Groups \u2014 view per-partition parked offsets, combined and per-partition lag Browse Messages \u2014 browse messages with JSON, plain text, and Avro encoding Dynamic Topic Configuration \u2014 create and configure new topics with dynamic configuration Configurable Authentification \u2014 secure your installation with optional Github/Gitlab/Google OAuth 2.0 1. Additional details can be found on the Kafka UI website. Starting the Kafka UI Before starting the Kafka UI service, you will need to choose a port number to expose the UI to the network. In your reservation you will find two open port numbers: Open Port 1 - Server: useast.services.cloud.techzone.ibm.com Port: 12345 Open Port 2 - Server: useast.services.cloud.techzone.ibm.com Port: 23456 These ports are available for any service that you decide to use in the machine. The first open port maps to the internal port 10000, while the second open port is for 10001. In this notebook, Open Port 2 (10001) is going to be used as the Kafka UI port. When accessing the Kafka UI, you will need to use the following address in your browser (with the URL and port number adjusted to your reservation): useast . services . cloud . techzone . ibm . com : 23456 The next command will start the Kafka UI service. Start Kafka UI If you want to change to open port #1, change the -p 10001:8080 to -p 10000:8080 . Start Kafka UI sudo docker run --detach --name kafkaui -p 10001:8080 -e DYNAMIC_CONFIG_ENABLED=true provectuslabs/kafka-ui Stop Kafka UI If you want to stop the Kafka UI service, run the following docker command. Stop Kafka UI sudo docker stop kafkaui Kafka UI Overview The following section describes some of the screens that you will use when accessing the Kafka service running on your watsonx server. Initial Connection In a new browser tab, enter the name of your watsonx.data server and the port number assigned to Open Port #2 (10001) in your reservation. Open Port 2 - Server: useast.services.cloud.techzone.ibm.com Port: 23456 You should see the initial connection dialog displayed. Note that there is no authentication performed by this interface. Configure the Kafka Connection In order to get the Kafka UI running, you must add details about the Kafka server that is running. Since the Kafka UI is running inside the watsonxdata server, the addresses reflect the internal address of the server, rather than a traditional URL.

Kafka combines three capabilities so you can implement your use cases for event streaming. To publish (write) and subscribe to (read) streams of events, including continuous import/export of your data from other systems. To store streams of events durably and reliably for as long as you want. To process streams of events as they occur or retrospectively. Producers and Consumers Producers are those client applications that publish (write) events to Kafka, and consumers are those that subscribe to (read and process) these events. In Kafka, producers and consumers are fully decoupled and agnostic of each other, which is a key design element to achieve the high scalability that Kafka is known for. For example, producers never need to wait for consumers. Kafka provides various guarantees such as the ability to process events exactly-once. Events Events are organized and durably stored in topics. Very simplified, a topic is similar to a folder in a filesystem, and the events are the files in that folder. An example topic name could be \"payments\". Topics in Kafka are always multi-producer and multi-subscriber: a topic can have zero, one, or many producers that write events to it, as well as zero, one, or many consumers that subscribe to these events. Events in a topic can be read as often as needed\u2014unlike traditional messaging systems, events are not deleted after consumption. Instead, you define for how long Kafka should retain your events through a per-topic configuration setting, after which old events will be discarded. Kafka's performance is effectively constant with respect to data size, so storing data for a long time is perfectly fine. 1. Additional details can be found on the Kafka website . 2. Thanks to Chunyu Jiang for prototyping the Kafka connector and suggestions on the code. Creating a Kafka Service The first step is to create a Kafka service in your system. The following text needs to be placed into a file called kafka-compose.yaml . This is the control file required to create the Kafka Docker images. The system does not contain any topics when it starts up. kafka-compose.yaml file version: '3' services: zookeeper: image: confluentinc/cp-zookeeper:latest environment: ZOOKEEPER_CLIENT_PORT: 2181 ZOOKEEPER_TICK_TIME: 2000 ports: - 22181:2181 kafka: image: confluentinc/cp-kafka:latest depends_on: - zookeeper ports: - 29092:29092 environment: KAFKA_BROKER_ID: 1 KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181 KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092,PLAINTEXT_HOST://watsonxdata:29092 KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1 Now we can start the Kafka and Zookeeper service. The default Kafka port is 29092. You need to be the root user to issue this command. Start Kafka sudo docker compose -p kafka -f kafka-compose.yaml up --detach Registering the Kafka Service The next step is to register the Kafka service with watsonx.data. Navigate to your watsonx.data UI screen and click on the infrastructure icon. If you see a dotted outline around the Presto engine, this means that the service has not yet started. Make sure that the outline is solid before attempting to add a new Kafka connection. Select the Add database option and select Apache Kafka as the source. Enter the following settings into the dialog. Display name - kafka Hostname - watsonxdata Port - 29092 Catalog name - kafka Note : Watsonx.data 1.1.3 includes a topics line where you can include the list of topics. This was removed in 1.1.4. Once you have entered these values into the panel, use the Test Connection link to make sure the Kafka server is reachable. Once you register the Kafka service, you should see it reflected in the infrastructure screen. At this point you must associate the Kafka service with the Presto engine. Hover over the Kafka catalog until you see the association icon. Click on that to view the Manage associations dialog. Select the presto-01 engine and press Save and restart engine. The Kafka service should now show as connected to the Presto engine. Create a Table Definition File Before you can access the Kafka topics, you must generate a JSON file which describes the contents of the topic. The format of this file is not described in the watsonx.data documentation. Instead, you must refer to the Presto documentation that includes an example of the syntax and usage of this file: Presto Kafka Connection configuration Presto Kafka Example The basic structure of the JSON file is: { \"tableName\" : \"\" , \"schemaName\" : \"\" , \"topicName\" : \"\" , \"key\" : {}, \"message\" : { \"fields\" : [] } } At a minimum you must provide the table name, the schema name and the topic name. The key field refers to the key within the Kafka message which can be used to identify the row in the output. The message field contains a descriptor of each field found in the Kafka message. The Presto documentation describes the data types and formats that are allowed in configuration file. This notebook will create a topic called orders which will be viewed as a table called orders . While a schema called purchase has been specified, it is not used when the topic is registered in watsonx.data. Watsonx.data using the schema name of default when registering a topic. The preferred name of the file should be <schema><table>.json but it is not a requirement. The following JSON file describes the contents of the Kafka topic being used in the Jupyter notebook example. Although the message descriptor has been created, the current version of watsonx.data does not use this information when displaying the data. Sample JSON Topic Descriptor { \"tableName\": \"orders\", \"schemaName\": \"purchase\", \"topicName\": \"orders\", \"key\": { \"dataFormat\": \"raw\", \"fields\": [ { \"name\": \"kafka_key\", \"dataFormat\": \"LONG\", \"type\": \"BIGINT\", \"hidden\": \"false\" } ] }, \"message\": { \"dataFormat\": \"json\", \"fields\": [ { \"name\": \"order_id\", \"mapping\": \"order_id\", \"type\": \"INTEGER\" }, { \"name\": \"customer_key\", \"mapping\": \"customerKey\", \"type\": \"BIGINT\" }, { \"name\": \"customer_id\", \"mapping\": \"customer_id\", \"type\": \"INTEGER\" }, { \"name\": \"product_id\", \"mapping\": \"product_id\", \"type\": \"INTEGER\" }, { \"name\": \"quantity\", \"mapping\": \"quantity\", \"type\": \"INTEGER\" }, { \"name\": \"unit_price\", \"mapping\": \"unit_price\", \"type\": \"DOUBLE\" } ] } } Add a Topic to watsonx.data Once you have create the table definition file, you must register the topic to watsonx.data. In the Infrastructure window, select the Kafka database. The details panel will display information about the Kafka service. Near the bottom of the screen there is a Add Topics button. Once you press the Add topics button, a dialog will prompt you to drag and drop or select .json files from your operating system. Select the file that was created found in your local directory. The selected file will now appear as a topic in the list. You can continue to add more topics as required. The list can have items added or removed as topics change in the Kafka environment. Once the topics have been added, press the Save button to register the topic to the watsonx.data server. At this point the topic has been registered and you can start querying the Kafka topics. Querying Kafka Topics You can now start querying the topics that you have registered to the system. The following example is based on a topic called orders. See the Jupyter notebook example for instructions on how to create a topic and populate it with data. Switch to the Data Manager view. You should see the Kafka catalog in the list on the left. The schema is called default (not purchase which we had placed into the table descriptor). If you don't see the service, you may need to refresh the screen to wait for Presto to become available. Clicking on the orders table will display information about this topic. When data is loaded into the queue, you will be able to click on the Data sample tab to look at the messages that have come in. Note that the data will not be shown on your system since the messages have not been loaded into the queue.

How do we know that this data is based on Apache iceberg? If you open the file under metadata , you should see metadata information for the data we are storing in parquet file format. Do I really need Apache Iceberg? The following example demonstrates why you need something like Apache Iceberg to manage the files. Metadata is stored in the Parquet file format, but only for the single parquet file. If we add more data/partitions, the data is split into multiple Parquet files, and we don\u2019t have a mechanism to get the table to parquet files mapping.

Exit from the Sandbox. exit MinIO CLI The MinIO Client mc command line tool provides an alternative to UNIX commands like ls , cat , cp , mirror , and diff with support for both file systems and Amazon S3-compatible cloud storage services. The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior. Complete details and restrictions around the use of the CLI command can be found on the MinIO Client page. You can use the MinIO CLI from a variety of clients. The MinIO ports are open in the developer edition image, which provides an alternative to loading data directly from your workstation rather than using the MinIO UI interface. Minio System Alias Before running commands against the MinIO server, an alias must be created that includes the access and secret key. The values can be extracted from the system by listing the contents of the /certs/passwords file or by running the passwords command as the root user. cat /certs/passwords The values for the MinIO access and secret key can also be exported with the following code: export LH_S3_ACCESS_KEY=$(docker exec ibm-lh-presto printenv | grep LH_S3_ACCESS_KEY | sed 's/.*=//') export LH_S3_SECRET_KEY=$(docker exec ibm-lh-presto printenv | grep LH_S3_SECRET_KEY | sed 's/.*=//') echo \"MinIO Userid : \" $LH_S3_ACCESS_KEY echo \"MinIO Password: \" $LH_S3_SECRET_KEY The alias command has the following syntax: mc alias set alias-name hostname:port access_key secret_key For a local connection, we will use the following values: Alias Name - watsonxdata Hostname \u2013 watsonxdata Port \u2013 9000 Access Key \u2013 $LH_S3_ACCESS_KEY Secret Key - $LH_S3_SECRET_KEY If you are using an external client to connect to the MinIO service, you will need the URL and Port number from the TechZone reservation. The access key and secret key will be the same values that are found above. Hostname \u2013 region.services.cloud.techzone.ibm.com Port \u2013 12345 The alias for local access is found below. mc alias set watsonxdata http://watsonxdata:9000 $LH_S3_ACCESS_KEY $LH_S3_SECRET_KEY Added `watsonxdata` successfully. List Buckets The mc command provides us with a number of commands that allows us to manage buckets and files within them. The following command checks to see what buckets currently exist in the system. mc ls tree watsonxdata [2023-09-29 14:38:19 EDT] 0B hive-bucket/ [2023-09-29 14:38:19 EDT] 0B iceberg-bucket/ You can view the contents of a bucket by traversing down the path. mc ls tree watsonxdata/hive-bucket [2023-10-13 10:34:36 EDT] 0B gosalesdw/ [2023-10-13 10:34:36 EDT] 0B hive_sql/ [2023-10-13 10:34:36 EDT] 0B ontime/ [2023-10-13 10:34:36 EDT] 0B taxi/ Create a Bucket At this point we will create a new bucket to hold some data. Use the mb (make bucket) command. The command requires the alias name for the MinIO connection followed by the name of the bucket. mc mb alias-name/new-bucket The following code will create a new bucket in the system called sampledata . mc mb watsonxdata/sampledata Bucket created successfully `watsonxdata/sampledata`. We can double check that the bucket it there. mc ls tree watsonxdata [2023-09-29 14:38:19 EDT] 0B hive-bucket/ [2023-09-29 14:38:19 EDT] 0B iceberg-bucket/ [2023-10-13 10:39:47 EDT] 0B sampledata/ Loading Data One of the most powerful features of the MinIO CLI is its ability to load data directory from your workstation into the bucket, rather than having to use the MinIO UI. It is also significantly faster than using the UI interface. The next example will load data into the bucket that was just created. The directory that we will be using to load data from is called /sampledata and found in the root directory of the watsonx.data server. ls /sampledata/csv gosales ontime taxi Next we will load the data from each one of these directories into the sampledata bucket. The mc command allows you to select which files to place into a bucket, or an entire directory with recursion. In this case we are loading all three directories the files into the bucket. Note the use of the / at the end of the directory name to prevent the directory name csv from being used as the high-level directory name in the target bucket. mc cp --recursive /sampledata/csv/ watsonxdata/sampledata/ ...data/csv/taxi/taxi.csv: 306.16 MiB / 306.16 MiB \u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501 147.91 MiB/s 2s We can double-check that our files are there with the --files option: mc tree --files watsonxdata/sampledata/ watsonxdata/sampledata/ \u251c\u2500 gosales \u2502 \u251c\u2500 DIST_INVENTORY_FACT.csv \u2502 \u251c\u2500 DIST_PRODUCT_FORECAST_FACT.csv \u2502 \u251c\u2500 DIST_RETURNED_ITEMS_FACT.csv \u2502 \u251c\u2500 DIST_RETURN_REASON_DIM.csv .... \u2502 \u251c\u2500 EMP_EMPLOYEE_DIM.csv \u2502 \u251c\u2500 SLS_SALES_TARG_FACT.csv \u2502 \u251c\u2500 gosales_createtable.sql \u2502 \u2514\u2500 gosales_load_postgres.sql \u251c\u2500 ontime \u2502 \u251c\u2500 aircraft.csv \u2502 \u251c\u2500 airline_id.csv \u2502 \u251c\u2500 airport_id.csv \u2502 \u251c\u2500 cancellation.csv \u2502 \u2514\u2500 ontime.csv \u2514\u2500 taxi \u2514\u2500 taxi.csv Delete a File or Bucket Use the rb (Remove bucket) command to remove a bucket and its contents. You can remove individual objects by using the rm (Remove) command by fully qualifying the object. The next command will remove the ontime.csv file from the ontime folder. mc rm watsonxdata/sampledata/ontime/ontime.csv Removed `watsonxdata/sampledata/ontime/ontime.csv`. The delete bucket command will fail if you still have data in the bucket. mc rb watsonxdata/sampledata mc: `watsonxdata/sampledata` is not empty. Retry this command with \u2018--force\u2019 flag if you want to remove `watsonxdata/sampledata` and all its contents Adding the --force option will remove the bucket and all the data in it.

Capture historical data about Presto queries The Query History Monitoring and Management (QHMM) service captures historical data about Presto queries and events. The historical data is stored in a MinIO bucket and you can use the data to understand the queries that were run and to debug the Presto engine. Improved query performance with Metastore, File list, and File metadata caching You can now capture and track the DDL changes in watsonx.data by using an event listener. Ingest data by using Spark You can now use the IBM Analytics Engine powered by Apache Spark to run ingestion jobs in watsonx.data. Integration with Db2 and Netezza Performance Server You can now register Db2 or Netezza Performance Server engines in watsonx.data console. New connectors You can now use connectors in watsonx.data to establish connections to the following types of databases: Teradata Delta Lake Elasticsearch SAP HANA SingleStoreDB Snowflake Teradata Db2 Upgraded to 11.5.9 What's new in Db2 11.5.9 Reference October 6, 2023 (1.0.3) Updated the lab to GA 1.0.3 code What's new in watsonx.data version 1.1.0 Image now available in 10 data centers with simpler provisioning Requesting an Image Removed VPN Requirement External URLs and Ports for all UI Services watsonx.data Ports Added PostgreSQL and MySQL databases Postgres Connection MySQL Connection Added Jupyter notebook examples Jupyter Notebook support Fixed Presto certificate to support TechZone addresses without updating /etc/hosts Watsonx.data Connection Certificate Added standalone Spark server to show connectivity to the Presto database Accessing watsonx.data with Spark Added watsonx.data Client code Watsonx.data client utilities Added MinIO CLI interface MinIO CLI Exposed external ports for MinIO, Db2, MySQL, PostgreSQL, Hive, PrestoDB watsonx.data Ports VNC Interface disabled by default Enabling VNC Access Added Ingesting data chapter Ingesting Data July 25, 2023 (1.0.1) Updated the lab to GA 1.0.1 code Automated start of watsonx.data and simplification of many of the sections Removed the Ingest section until a new version is available Added Db2 and PostgreSQL connection details June 12, 2023 (1.0.0) Clarified some commands and added an Appendix on common issues.

System Utilities There are several commands that have been added to the watsonx.data developer edition to make it easier to manage the system. These commands are not part of the original installation, but are provided as a convenience for managing the system. All commands require that you connect to the server as the root user. Use the following commands to connect to the watsonx.data system. SSH into the watsonx.data server ssh -p port watsonx@region.services.cloud.techzone.ibm.com Password is watsonx.data . Next switch to the root userid. Switch to the root user sudo su - As the root user, switch to the bin directory. Switch to the bin directory cd /root/ibm-lh-dev/bin Watsonx.data Shutdown Use the stop-watsonx command to stop the watsonx.data system. Watsonx.data shutdown stop-watsonx The stop-watsonx command will stop the Milvus service before stopping the watsonx.data services. If you stop watsonx.data prior to Milvus, the watsonx.data catalog will not be properly updated with the Milvus status, and error messages will be generated about invalid SQL insert statements. This is caused by the catalog service (hosted in PostgreSQL) becoming unavailable because of it being shutdown. You can manually stop the service using either of these commands: Stop watsonx.data service systemctl stop watsonx.service Alternatively, you can use the following commands. You must be in the /root/ibm-lh-dev/bin directory to issue these commands. Stop watsonx.data using direct commands cd /root/ibm-lh-dev/bin ./stop-milvus ./stop Make sure you follow the exact sequence of commands or else you will get a shutdown error with Milvus. Watsonx.data Startup To start the watsonx.data system, use the start-watsonx command. Watsonx.data startup start-watsonx The start-watsonx command will start watsonx.data service before the Milvus service. If you start Milvus prior to starting watsonx.data, the watsonx.data catalog will not be properly updated with the Milvus status, and error messages will be generated about invalid SQL insert statements. You can manually start the service using either of these commands: Start watsonx.data service systemctl start watsonx.service Alternatively, you can use the following commands. You must be in the /root/ibm-lh-dev/bin directory to issue these commands. Start watsonx.data using direct commands cd /root/ibm-lh-dev/bin export LH_RUN_MODE = diag ./start ./start-milvus Startup time Using the systemctl or start command will take a few minutes to complete. There will not be any status messages displayed when using the systemctl command, so if you want to watch the startup sequence, use the start command instead. You must set LH_RUN_MODE to diag to open up the ports in the various watsonx.data containers. If you do not set this environment variable, you will not be able to access several services externally. System Status You can check the status with the following command. System Status ./status.sh --all Output will look similar to: using /root/ibm-lh-dev/localstorage/volumes as data root directory for user: root/1001 infra config location is /root/ibm-lh-dev/localstorage/volumes/infra lhconsole-ui running 0.0.0.0:9443->8443/tcp, :::9443->8443/tcp lhconsole-nodeclient-svc running 3001/tcp lhconsole-javaapi-svc running 8090/tcp lhconsole-api running 3333/tcp, 8081/tcp ibm-lh-presto running 0.0.0.0:8443->8443/tcp, :::8443->8443/tcp ibm-lh-hive-metastore running ibm-lh-postgres running 5432/tcp ibm-lh-minio running Stop and Start Presto If you need to start or stop the Presto engine, use the following commands. Stop Presto stop-presto Alternatively, you can use the watsonx.data commands. Stop Presto using watsonx.data commmands cd /root/ibm-lh-dev/bin ./stop_service ibm-lh-presto To start Presto, use the following commands. Start Presto start-presto Alternatively, you can use the watsonx.data commands. Start Presto using watsonx.data commmands cd /root/ibm-lh-dev/bin export LH_RUN_MODE = diag ./start_service ibm-lh-presto To check on the current status of the Presto engine, use the check-presto command.

This command typically takes less than 1 minute to download the code. git clone https://github.com/apache/superset.git The docker-compose-non-dev.yml file needs to be updated so that Apache Superset can access the same network that watsonx.data is using. cd ./superset cp docker-compose-non-dev.yml docker-compose-non-dev-backup.yml sed '/version: \"3.7\"/q' docker-compose-non-dev.yml > yamlfix.txt cat <<EOF >> yamlfix.txt networks: default: external: True name: ibm-lh-network EOF sed -e '1,/version: \"3.7\"/ d' docker-compose-non-dev.yml >> yamlfix.txt We update the Apache Superset code to version 2.1.0 . sed 's/\\${TAG:-latest-dev}/2.1.0/' yamlfix.txt > docker-compose-non-dev.yml Use docker-compose to start Apache Superset. docker compose -f docker-compose-non-dev.yml up The docker compose command will download the necessary code for Apache Superset and start the service. The terminal session will contain the logging information for the service. The process is running in the foreground so you will see all the messages being produced by the program. If you want to stop the service at any time you will need to press CTRL-C. If you close this terminal window at any time, the process will stop. When you see \"Init Step 4/4\", the service is ready for connections. If you have already installed Apache Superset and you stopped it, there is no need to reinstall the program. Go back to the /home/watsonx/superset directory and run the docker compose program again: Once the service is running, open your browser and navigate to the URL and port that were provided in your TechZone reservation. The credentials for Apache Superset are userid admin , Password admin . \u2003 Setup a Database Connection to watsonx.data Open another terminal window for this next step. Once Apache Superset has started loading examples, you can issue the following command as watsonx or root . docker cp /certs/lh-ssl-ts.crt superset_app:/tmp/lh-ssl-ts.crt In the Apache Superset console, press the Settings button on the far right and select Database connections. Then select the [+ DATABASE] option on the far-right side of the panel. \u2003 A connection dialog will display. Select Presto as the database connection type. In the SQLALCHEMY URI field, enter the following information to connect to the hive_data catalog which contains the GOSALES, ONTIME, and TAXI data. presto://ibmlhadmin:password@ibm-lh-presto-svc:8443/hive_data Enter the following information to connect to the iceberg_data catalog which will contain any tables you created when running the examples in the lab. presto://ibmlhadmin:password@ibm-lh-presto-svc:8443/iceberg_data Select the Advanced tab.

Create reports/charts/dashboards Once the connection has been tested and created for watsonx.data, we can click on Dataset and create a new dataset based on the customer table in the tiny schema. Reports/dashboards can then be created using the very intuitive Superset interface. Note : The Apache Superset team removes, inserts and updates charts on a frequent basis with no advance notification. The example you see below may not be exactly the same when you run the code. This is not something that we can control in the demonstration environment. Select Datasets at the top of the Apache Superset window. Press [+ DATASET]. In the Database field, select Presto. The schemas will take a few seconds to load. Select the workshop schema. Select customer from the list. The display will show the columns associated with this table. On the bottom right-hand corner is a button named CREATE DATASET AND CREATE CHART. Press that to display the following panel. To create a simple Bar Chart, we start by selecting the Bar Chart icon. If you click it once it displays information about the chart type. If you double-click it, the chart builder screen will display. Click on the mktsegment field and drag it into the DIMENSIONS field. Then drag the acctbal field into the METRICS field. The program will ask how the field is to be computed. Select AVG from the list and SAVE. Now press the CREATE CHART button found at the bottom of the screen. Try to create different charts/dashboards if you have time. When you are finished using Apache Superset, press CTRL-C (Control-C) in the terminal window that you used to start it. This will stop the program and release the resources it is using. If you press CTRL-C twice, it immediately kills the program, but it may lose some of the work that you may have done.","title":"Apache Superset"},{"location":"wxd-superset/#reportingdashboarding-using-apache-superset","text":"Apache Superset is not a part of watsonx.data and is only used to demonstrate the capability to connect to watsonx.data from other BI/Reporting tools.

Here is a list of common questions, problems, and potential solutions. What are the passwords for the services A SQL Statement failed but there are no error messages Apache Superset isn't Starting Apache Superset screens differ from the lab Too many incorrect logins using VNC and now I'm blocked Presto doesn't appear to be working Displaying Db2 Schema is failing Queries are failing with a 400 code Queries are failing with a 200 or 500 code Queries are failing with memory errors SSH, VNC and watsonx.data UI are not working No access to Presto/Minio UI after restart Firefox and Chrome freeze when connecting to MinIO What are the passwords for the services? See the section on Passwords . You can get all passwords for the system when you are logged in as the watsonx user by using the following command. cat /certs/passwords You can also use the Jupyter notebook link to display the userids and passwords for the services. A SQL Statement failed, but there are no error messages You need to use the Presto console and search for the SQL statement. Click on the Query ID to find more details of the statement execution and scroll to the bottom of the web page to see any error details. Apache Superset isn't Starting If Superset doesn't start for some reason, you will need to reset it completely to try it again. First make sure you are connected as the watsonx user not root . Make sure you have stopped the terminal session that is running Apache Superset. Next remove the Apache Superset directory. sudo rm -rf /home/watsonx/superset We remove the docker images associated with Apache Superset. If no containers or volumes exist you will get an error message. docker ps -a -q --filter \"name=superset\" | xargs docker container rm --force docker volume list -q --filter \"name=superset\" | xargs docker volume rm --force Download the superset code again. git clone https://github.com/apache/superset.git The docker-compose-non-dev.yml file needs to be updated so that Apache Superset can access the same network that watsonx.data is using. cd ./superset cp docker-compose-non-dev.yml docker-compose-non-dev-backup.yml sed '/version: \"3.7\"/q' docker-compose-non-dev.yml > yamlfix.txt cat <<EOF >> yamlfix.txt networks: default: external: True name: ibm-lh-network EOF sed -e '1,/version: \"3.7\"/ d' docker-compose-non-dev.yml >> yamlfix.txt We update the Apache Superset code to version 2.1.0 . sed 's/\\${TAG:-latest-dev}/2.1.0/' yamlfix.txt > docker-compose-non-dev.yml Use docker-compose to start Apache Superset. nohup docker compose -f docker-compose-non-dev.yml up & The nohup command will issue a message indicating that output will be directed to the nohup.out file. It takes some time for the service to start, so be patient! You can view any output from the Apache Superset system by viewing the nohup.out file in the directory where you installed superset. Apache Superset screens differ from the lab The Apache Superset project makes frequent changes to the types of charts that are available. In some cases they remove or merge charts. Since these charts changes are dynamic, we are not able to guarantee that our examples will look the same as what you might have on your system. Presto doesn't appear to be working If you find that the watsonx.data UI is generating error messages that suggest that queries are not running, or that the Presto service is dead, you can force a soft restart of Presto with the following command: docker restart ibm-lh-presto This will restart the Presto server. If you find that does not fix your problem, you will need to do a hard reset using the following commands: sudo su - cd /root/ibm-lh-dev/bin ./stop_service ibm-lh-presto ./start_service ibm-lh-presto check_presto The command will wait until the service is running before exiting. Displaying Db2 Schema is failing Occasionally when attempting to expand the Db2 catalog (schema), the watsonx.data UI will not display any data or issue an error message. You can try refreshing the browser (not the refresh icon inside the UI) and try again. If you find that this is failing again, open the Query workspace and run the following SQL (replace db2_gosales with the name you cataloged the database with). select count(*) from db2_gosales.gosalesdw.go_org_dim The result should be 123 and hopefully the tables that are part of the schema will display for you. Queries are failing with a 400 code The watsonx.data UI will log you out after a period of inactivity, but doesn't tell you that this has happened. When you attempt to run a query, the error that is returned (400) indicates that you need to log back in again. Queries are failing with a 200 or 500 code A 500 code may indicate the watsonx.data UI has a problem connecting with the Presto engine. First log out of the console and trying logging back on. If that fails to solve the problem, you will need to reboot the console. Open up a terminal window into the server: As the root user, restart the docker container that is running the watsonx.data UI. docker restart lhconsole-nodeclient-svc Queries fail become of insufficient memory If you are running a complex query, you may get an error message similar to \"Query exceeded per-node user memory limit\" or a something similar. Watsonx.data (Presto) attempts to limit the amount of resources being using in a query and will stop a query if it exceeds a certain threshold. You can change the behavior of the system by making the following changes. Note : During this step you will disconnect anyone running a query on the server. What you need to do is make a change to the configuration settings of the Presto engine. AS the root user, enter the docker container for the presto engine: docker exec -it ibm-lh-presto /bin/bash Next, copy the original config file to a safe place in case we make an error: cp /opt/presto/etc/config.properties /opt/presto/etc/config.properties.backup Then update the properties file. cat >> /opt/presto/etc/config.properties << EOL experimental.spiller-spill-path=/tmp experimental.spiller-max-used-space-threshold=0.7 experimental.max-spill-per-node=10GB experimental.query-max-spill-per-node=10GB experimental.spill-enabled=true query.max-memory=10GB query.max-memory-per-node=10GB query.max-total-memory-per-node=10GB query.max-total-memory=10GB EOL Doublecheck that it worked. cat /opt/presto/etc/config.properties | grep experimental experimental.max-spill-per-node=10GB experimental.query-max-spill-per-node=10GB experimental.spill-enabled=true experimental.spiller-max-used-space-threshold=0.7 experimental.spiller-spill-path=/tmp If it is all good then exit the container. exit And now we restart the container. Make sure that you don't impact other users! docker restart ibm-lh-presto Now try running your query again. Note : Once you make this change, only restart presto using the above command, otherwise you will lose the changes. Too many incorrect logins using VNC and now I'm blocked from connecting If you lock yourself out of VNC because of too many incorrect logins, you can reset the service with the following commands. Connect as the root user then run the following command and you should be able to log in again. systemctl restart vncserver@:1 exit SSH, VNC and watsonx.data UI are not working Symptoms: You've tried to use SSH to log into the system, and you get a timeout error. All the Web-based UIs (watsonx.data UI, Presto) fail. Find your email message that contains details of your reservation. Details of what the reservations and the page containing details of the reservation can be found in the Accessing the reservation section. Once the details appear, scroll down to the bottom of the web page, and you will see the VM Remote Console button. You can access the logon screen of the virtual machine by pressing the VM Remote Console button. Clicking on this button will display the logon screen for the server. If you see this screen, the system is running and there is something wrong the watsonx.data service (see instructions below). If you see the following screen: This means your server has been turned off. Click on the Power on button. Make sure to press the Yes button to turn the power on! In a few minutes you should see the logon screen again. Wait for a few minutes for all the services to start, and then you will be able to use SSH, VNC, and watsonx.data UI. Reset watsonx.data If you can log into the watsonx userid using the VM Remove console, you can reset the watsonx.data server with the following steps. SSH into the server as the root user. Then switch to the development code bin directory. cd /root/ibm-lh-dev/bin Check the status of the system with the following command. ./status.sh --all Output will look similar to: using /root/ibm-lh-dev/localstorage/volumes as data root directory for user: root/1001 infra config location is /root/ibm-lh-dev/localstorage/volumes/infra lhconsole-ui running 0.0.0.0:9443->8443/tcp, :::9443->8443/tcp lhconsole-nodeclient-svc running 3001/tcp lhconsole-javaapi-svc running 8090/tcp lhconsole-api running 3333/tcp, 8081/tcp ibm-lh-presto running 0.0.0.0:8443->8443/tcp, :::8443->8443/tcp ibm-lh-hive-metastore running ibm-lh-postgres running 5432/tcp ibm-lh-minio running If the any of the services are not running, you will need to restart the system with the following set of commands. cd /root/ibm-lh-dev/bin ./stop.sh export LH_RUN_MODE=diag ./start.sh Wait for all services to start and then check to see if you can connect to the watsonx.data UI. No access to Presto/Minio UI after restart If you are using a TechZone image that has been suspended, or restarted, you may come across a situation where you are unable to connect to any service that uses the http protocol. The watsonx.service needs to have a diagnostic flag set that opens up these ports, and sometimes this diagnostic setting is not being updated. To manually stop and start the system, you will need to connect with root user privileges and run the following commands: sudo su - cd /root/ibm-lh-dev/bin ./stop.sh export LH_RUN_MODE=diag ./start.sh This set of commands will stop all the services in watsonx.data and restart them in diagnostic mode. This will now open the http ports for use. Firefox and Chrome freeze when connecting to MinIO Firefox and Chrome on OSX will occasionally freeze when connecting to the MinIO console. The Safari browser is much more reliable. This problem appears to be caused by some features which are not properly handled by these browsers.","title":"Troubleshooting"},{"location":"wxd-troubleshooting/#troubleshooting-watsonxdata","text":"Although we have tried to make the lab as error-free as possible, occasionally things will go wrong.

A role is a set of privileges that control the actions that users can perform. Authorization is granted by assigning a specific role to a user, or by adding the user to a group that has been assigned one or more roles. Access control at the infrastructural level allows permissions to be granted on the engines, catalogs, buckets, and databases. Roles for these components include Admin, Manager, User, Writer, and Reader (depending on the component). Access to the data itself is managed through data control policies. Policies can be created to permit or deny access to schemas, tables, and columns. User account management and access management varies between the different deployment options for watsonx.data. For instance, in the managed cloud service (SaaS), the service owner would need to invite other users to the environment and give them appropriate service access. With the standalone software, users can be added within the console\u2019s Access control page. In the Developer Edition, users can be added using a command line tool. Credits: Portions of text found in this section were copied from Kelly Schlamb's watsonx.data L3 course. User Administration This lab is using the Developer edition of the watsonx.data software, which means that the Access control panel is not available. In order to manage users, the user-mgmt command will need to be used. The user-mgmt command is found in the /root/ibm-lh-dev/bin directory. Examples of using the command are found below. Add a User The syntax for adding a user is: ./user-mgmt add-user <username> [ User | Admin ] <password> The values are: username - The name of the user [User|Admin] - The type of user. Note that the type of user is case-sensitive! password - The password for the user. The following command will add the user watsonx with a password of watsonx.data . This will be a standard user with no privileges. The first step is to make sure you are connected as the root user in watsonx.data server and have switched to the proper directory. sudo su - cd /root/ibm-lh-dev/bin The next command will add a new user to the system. ./user-mgmt add-user watsonx User watsonx.data Change a User's Password The syntax for changing a password is: ./user-mgmt change-password <username> This command will require that the user enter the new password. You can issue the command and provide the new password at the prompt. The other way to simulate the enter command is to use the Linux yes function which repeats a value multiple times. The following command will change the password of watsonx to hellowatson . yes hellowatson | ./user-mgmt change-password watsonx Validate a User's Password You can validate a password by using the following command: ./user-mgmt test-user-cred <username> The username is the name of the user that you want to check the password for. This command will require that the user enter the existing password to check it. You can use the yes function (as described above) to simulate the enter command. The following command will check that we have changed the password of watsonx to hellowatson . yes hellowatson | ./user-mgmt test-user-cred watsonx Delete a User To delete a user, use the following command: ./user-mgmt delete-user <username> The error messages on group ownership can be safely ignored. The following command will remove our watsonx user. ./user-mgmt delete-user watsonx Roles and Policies In this section you will add a new user and provide them with privileges over the infrastructure and data. First start by adding a new user to the watsonx.data system. If you haven't already, make sure you are connected to the server as the root user and are in the /root/ibm-lh-dev/bin directory. Add user1 to the system with a password of password . ./user-mgmt add-user user1 User password Access Control To view what users are currently authorized to use the system, select the Access control icon found on the left side of the watsonx.data UI. A list of objects that make up the watsonx.data infrastructure are displayed. You can see that the objects are made up of: Engines Catalogs Buckets In a real-world scenario where a user will be querying data from a table, that user will need to be given a minimum of User access to an engine (to be able to run the query), User access for the catalog associated with the data (to be able to see the schema information associated with the table), and Reader access to the bucket associated with the data (to be able to read the data from object storage). Additionally, a policy has to be created to permit the user to access the table in question. Granting Access Select the presto-01 engine (highlighted in red above) to view the current users that have access to the engine. At this point, only the administrative user (ibmlhadmin) can use the Presto engine. Click on the Add Access button to add a new authorized user to the list. The role button has been selected in the dialog to show the role options of Admin, Manager, or User. An Admin user can grant any role to a user, while a Manager can only grant User privileges. For this lab, grant user1 \"user\" privileges and then press Add. Close the dialog by clicking on the [x] on the top right of the screen. Now user1 needs to be granted access to a catalog. In this case, the iceberg_data and hive_data catalogs are required for the Presto engine and are implicitly granted to the user. Click on the iceberg_data line to confirm that this is the case. You should see that user1 has already been granted access to the catalog. If your version of watsonx.data Developer Edition does not have access granted to user1 , add it manually using the same steps as for engine access. Close the dialog to return to the Access control screen. The final step is to grant access to the underlying buckets. Because user was implicitly granted access to the iceberg_data and hive_data catalogs, the underlying buckets iceberg-bucket and hive-bucket were also added to their access list. Click on iceberg-bucket to view the access control. Again, if user1 does not have access to the bucket, add access using the same steps as adding engine access. When done viewing the screen, close the dialog to return to the Access control dialog. Policies After access has been granted to engines, catalogs, and buckets, the final step is to create a policy to grant access to tables. Click on the Policy tab to display the current policies in place (there should be none). The Add Policy button is highlighted on the far right side of the screen. Pressing the button will display the new Access Control Policy dialog. Fill in the following information: Policy name: selectflights Description: blank Policy status: active You can always activate a policy after you have created it. Click Next. Here we need to select which schemas that the user will be able to access. For this example, select the ontime schema. After selecting the schema, a set of tables associated with the schema will be listed. You can choose which tables can be searched. If you choose an individual table, you can restrict which columns can be searched. Select the ontime table and then select the following columns (you will need to scroll down the page): flightdate reporting_airline flight_number_reporting_airline originairportid destairportid Once you have selected the columns, press the Next button to display the Rules dialog. The Rules dialog allows you to fine-tune what actions can be done by a user against the data. Press the Add Rule button to display the Add Rule dialog. Rules can be used to Allow actions or to Deny actions. In our example, we want to allow user1 to SELECT data from the data, but with no other options. Note : In production versions of watsonx.data, you can provide access to a group which makes it simpler to create a set of rules that apply to a group and then add a user to a group. That way a user will inherit the rules that were applied to the group rather than having to create rules for that individual. The developer edition displays GROUP as an option, but it is not implemented. Once the fields are filled in, press the Add button. You can continue to add additional rules to the list. Since we only want the one rule, select the Review button. Once you have confirmed that the data objects and rules look correct, press the Save button. The selectflights policy is now in place and is actively enforced. Before testing the policy enforcement, use the SQL icon on the left side to navigate to the hive_data catalog and view the schemas that are associated with it. Expand the ontime schema to view the tables and the columns that are available in the ontime table. When you connect as user1 , you will be able to compare what objects can be accessed from that userid. Testing Policy Enforcement To test whether the rules are enforced, you will need to log out of the current watsonx.data UI session. At the top of the Access Control screen, you will see the user icon on the top right. Clicking on the icon will display the logout dialog. Log out to the main watsonx.data UI screen. You will be prompted to confirm log out. Once back to the main log in panel, enter user and password into the dialog. Your watsonx.data UI should now display user1 . Navigate to the SQL icon and then select hive_data -> ontime -> ontime . You should notice that user1 was restricted to seeing only the ontime schema in the hive_data catalog. In addition, the user was restricted to accessing one of the tables ( ontime ) and 5 columns. Attempting to run a SELECT statement against all the data will result in a policy error. Correcting the SQL to include only permitted columns results in an answer set. The policy rules have been enforced for user1 , preventing them from viewing any other schemas or tables in the system. In addition, the SQL that they could execute was restricted to specific columns in the table. Before moving onto any other sections, make sure to log out as user1 and reconnect as the ibmlhadmin user.","title":"User Administration and Roles"},{"location":"wxd-useradmin/#watsonxdata-user-administration-and-roles","text":"Security and access control within watsonx.data are based on roles.

+<p>This section provides instructions on how to start and use the UI for <a href="https://github.com/provectus/kafka-ui">Apache Kafka Clusters.</a></p>
+<div class="admonition quote">
+<p class="admonition-title">UI for Apache Kafka is a free, open-source web UI to monitor and manage Apache Kafka clusters. The UI for Apache Kafka is a simple tool that makes your data flows observable, helps find and troubleshoot issues faster and deliver optimal performance. Its lightweight dashboard makes it easy to track key metrics of your Kafka clusters - Brokers, Topics, Partitions, Production, and Consumption.<sup>1</sup></p>
+</div>
+<p>Some of the key features:</p>
+<ul>
+<li>Multi-Cluster Management — monitor and manage all your clusters in one place</li>
+<li>Performance Monitoring with Metrics Dashboard — track key Kafka metrics with a lightweight dashboard</li>
+<li>View Kafka Brokers — view topic and partition assignments, controller status</li>
+<li>View Kafka Topics — view partition count, replication status, and custom configuration</li>
+<li>View Consumer Groups — view per-partition parked offsets, combined and per-partition lag</li>
+<li>Browse Messages — browse messages with JSON, plain text, and Avro encoding</li>
+<li>Dynamic Topic Configuration — create and configure new topics with dynamic configuration</li>
+<li>Configurable Authentification — secure your installation with optional Github/Gitlab/Google OAuth 2.0</li>
+</ul>

+
+<h2 id="starting-the-kafka-ui">Starting the Kafka UI</h2>
+<p>Before starting the Kafka UI service, you will need to choose a port number to expose the UI to the network. In your reservation you will find two open port numbers:</p>
+<ul>
+<li>Open Port 1 - Server: useast.services.cloud.techzone.ibm.com Port: 12345</li>
+<li>Open Port 2 - Server: useast.services.cloud.techzone.ibm.com Port: 23456</li>
+</ul>
+<p>These ports are available for any service that you decide to use in the machine. The first open port maps to the internal port 10000, while the second open port is for 10001. In this notebook, Open Port 2 (10001) is going to be used as the Kafka UI port. When accessing the Kafka UI, you will need to use the following address in your browser (with the URL and port number adjusted to your reservation):</p>
+<div class="highlight"><pre><span></span><code><span class="n">useast</span><span class="o">.</span><span class="n">services</span><span class="o">.</span><span class="n">cloud</span><span class="o">.</span><span class="n">techzone</span><span class="o">.</span><span class="n">ibm</span><span class="o">.</span><span class="n">com</span><span class="p">:</span><span class="mi">23456</span>
+</code></pre></div>
+<p>The next command will start the Kafka UI service. </p>
+<h3 id="start-kafka-ui">Start Kafka UI</h3>
+<p>If you want to change to open port #1, change the <span style="color:blue;background-color: transparent;">-p 10001:8080</span> to <span style="color:blue;background-color: transparent;">-p 10000:8080</span>.</p>

+</code></pre></div>
+</div>
+<h3 id="stop-kafka-ui">Stop Kafka UI</h3>
+<p>If you want to stop the Kafka UI service, run the following docker command.</p>

+</div>
+<h2 id="kafka-ui-overview">Kafka UI Overview</h2>
+<p>The following section describes some of the screens that you will use when accessing the Kafka service running on your watsonx server.</p>
+<h3 id="initial-connection">Initial Connection</h3>
+<p>In a new browser tab, enter the name of your watsonx.data server and the port number assigned to Open Port #2 (10001) in your reservation.</p>
+<ul>
+<li>Open Port 2 - Server: useast.services.cloud.techzone.ibm.com Port: 23456</li>
+</ul>
+<p>You should see the initial connection dialog displayed. Note that there is no authentication performed by this interface.</p>
+<p><img alt="Kafka 1" src="../wxd-images/watsonx-kafka-ui-1.png" /></p>
+<h3 id="configure-the-kafka-connection">Configure the Kafka Connection</h3>
+<p>In order to get the Kafka UI running, you must add details about the Kafka server that is running. Since the Kafka UI is running inside the watsonxdata server, the addresses reflect the internal address of the server, rather than a traditional URL. Use the following values:</p>
+<ul>
+<li>Cluster name - <span style="color:blue;background-color: transparent;">watsonxdata</span></li>
+<li>Bootstrap Server - <span style="color:blue;background-color: transparent;">watsonxdata</span></li>
+<li>Port - <span style="color:blue;background-color: transparent;">29092</span></li>
+</ul>
+<p>Then hit the Submit button.</p>
+<p><img alt="Kafka 1" src="../wxd-images/watsonx-kafka-ui-2.png" /></p>
+<h3 id="dashboard">Dashboard</h3>
+<p>The main dashboard provides information on Brokers, Topics, and Consumers. The watsonxdata Kafka service is shown with the only topic (orders) displayed.</p>
+<p><img alt="Kafka 1" src="../wxd-images/watsonx-kafka-ui-3.png" /></p>
+<h3 id="topic">Topic</h3>
+<p>The Topic menu lets view details of the various topics by selecting the topic name. Click on the orders topic to view more details about the topic.</p>

+<h1 id="kafka">Kafka</h1>
+<p>Apache Kafka® <sup style="color: blue;">1,2</span></sup> is an event streaming platform. Kafka combines three capabilities so you can implement your use cases for event streaming.</p>
+<ul>
+<li>To publish (write) and subscribe to (read) streams of events, including continuous import/export of your data from other systems.</li>
+<li>To store streams of events durably and reliably for as long as you want.</li>
+<li>To process streams of events as they occur or retrospectively.</li>
+</ul>
+<h4 id="producers-and-consumers">Producers and Consumers</h4>
+<p>Producers are those client applications that publish (write) events to Kafka, and consumers are those that subscribe to (read and process) these events. In Kafka, producers and consumers are fully decoupled and agnostic of each other, which is a key design element to achieve the high scalability that Kafka is known for. For example, producers never need to wait for consumers. Kafka provides various guarantees such as the ability to process events exactly-once.</p>
+<h4 id="events">Events</h4>
+<p>Events are organized and durably stored in topics. Very simplified, a topic is similar to a folder in a filesystem, and the events are the files in that folder. An example topic name could be "payments". Topics in Kafka are always multi-producer and multi-subscriber: a topic can have zero, one, or many producers that write events to it, as well as zero, one, or many consumers that subscribe to these events. Events in a topic can be read as often as needed—unlike traditional messaging systems, events are not deleted after consumption. Instead, you define for how long Kafka should retain your events through a per-topic configuration setting, after which old events will be discarded. Kafka's performance is effectively constant with respect to data size, so storing data for a long time is perfectly fine.</p>

+<p style="font-size: small;line-height: 0.4;"><sup>2. Thanks to Chunyu Jiang for prototyping the Kafka connector and suggestions on the code.</sup></p>
+
+<h2 id="creating-a-kafka-service">Creating a Kafka Service</h2>
+<p>The first step is to create a Kafka service in your system. The following text needs to be placed into a file called <code>kafka-compose.yaml</code>. This is the control file required to create the Kafka Docker images. The system does not contain any topics when it starts up.</p>
+<div class="admonition abstract">
+<p class="admonition-title">kafka-compose.yaml file</p>
+<div class="highlight"><pre><span></span><code>version: &#39;3&#39;
+services:
+zookeeper:
+   image: confluentinc/cp-zookeeper:latest
+   environment:
+      ZOOKEEPER_CLIENT_PORT: 2181
+      ZOOKEEPER_TICK_TIME: 2000
+   ports:
+      - 22181:2181
+
+kafka:
+   image: confluentinc/cp-kafka:latest
+   depends_on:
+      - zookeeper
+   ports:
+      - 29092:29092
+   environment:
+      KAFKA_BROKER_ID: 1
+      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
+      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092,PLAINTEXT_HOST://watsonxdata:29092
+      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
+      KAFKA_INTER_BROKER_LISTENER_NAME: PLAINTEXT
+      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
+</code></pre></div>
+</div>
+<p>Now we can start the Kafka and Zookeeper service. The default Kafka port is 29092. You need to be the root user to issue this command.</p>
+<div class="admonition abstract">
+<p class="admonition-title">Start Kafka</p>
+<div class="highlight"><pre><span></span><code>sudo docker compose -p kafka -f kafka-compose.yaml up --detach
+</code></pre></div>
+</div>
+<h2 id="registering-the-kafka-service">Registering the Kafka Service</h2>
+<p>The next step is to register the Kafka service with watsonx.data. Navigate to your watsonx.data UI screen and click on the infrastructure icon. If you see a dotted outline around the Presto engine, this means that the service has not yet started. Make sure that the outline is solid before attempting to add a new Kafka connection.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-add-database.png" /></p>
+<p>Select the Add database option and select Apache Kafka as the source.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-add-kafka.png" /></p>
+<p>Enter the following settings into the dialog.</p>
+<ul>
+<li>Display name - <span style="color:blue;background-color: transparent;">kafka</span></li>
+<li>Hostname - <span style="color:blue;background-color: transparent;">watsonxdata<span style="color:blue;background-color: transparent;"></li>
+<li>Port - <span style="color:blue;background-color: transparent;">29092<span style="color:blue;background-color: transparent;"></li>
+<li>Catalog name - <span style="color:blue;background-color: transparent;">kafka<span style="color:blue;background-color: transparent;"></li>
+</ul>
+<p><strong>Note</strong>: Watsonx.data 1.1.3 includes a topics line where you can include the list of topics. This was removed in 1.1.4.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-settings.png" /></p>
+<p>Once you have entered these values into the panel, use the Test Connection link to make sure the Kafka server is reachable. Once you register the Kafka service, you should see it reflected in the infrastructure screen.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-infrastructure.png" /></p>
+<p>At this point you must associate the Kafka service with the Presto engine. Hover over the Kafka catalog until you see the association icon. Click on that to view the Manage associations dialog.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-associate.png" /></p>
+<p>Select the presto-01 engine and press Save and restart engine. The Kafka service should now show as connected to the Presto engine.</p>
+<p><img alt="Add Database" src="../wxd-images/watsonx-kafka-associated.png" /></p>
+<h2 id="create-a-table-definition-file">Create a Table Definition File</h2>
+<p>Before you can access the Kafka topics, you must generate a JSON file which describes the contents of the topic. The format of this file is not described in the watsonx.data documentation. Instead, you must refer to the Presto documentation that includes an example of the syntax and usage of this file:</p>
+<ul>
+<li><a href="https://prestodb.io/docs/current/connector/kafka.html">Presto Kafka Connection configuration</a></li>
+<li><a href="https://prestodb.io/docs/current/connector/kafka-tutorial.html">Presto Kafka Example</a></li>
+</ul>
+<p>The basic structure of the JSON file is:
+<div class="highlight"><pre><span></span><code><span class="p">{</span><span class="w"></span>
+<span class="w">    </span><span class="nt">&quot;tableName&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;&quot;</span><span class="p">,</span><span class="w"></span>
+<span class="w">    </span><span class="nt">&quot;schemaName&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;&quot;</span><span class="p">,</span><span class="w"></span>
+<span class="w">    </span><span class="nt">&quot;topicName&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;&quot;</span><span class="p">,</span><span class="w"></span>
+<span class="w">    </span><span class="nt">&quot;key&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">{},</span><span class="w"></span>
+<span class="w">    </span><span class="nt">&quot;message&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">{</span><span class="w"></span>
+<span class="w">        </span><span class="nt">&quot;fields&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">[]</span><span class="w"></span>
+<span class="w">    </span><span class="p">}</span><span class="w"></span>
+<span class="p">}</span><span class="w"></span>
+</code></pre></div></p>
+<p>At a minimum you must provide the table name, the schema name and the topic name. The key field refers to the key within the Kafka message which can be used to identify the row in the output. The message field contains a descriptor of each field found in the Kafka message. The Presto documentation describes the data types and formats that are allowed in configuration file.</p>
+<p>This notebook will create a topic called <span style="color:blue;background-color: transparent;">orders</span> which will be viewed as a table called <span style="color:blue;background-color: transparent;">orders</span>. While a schema called <span style="color:blue;background-color: transparent;">purchase</span> has been specified, it is not used when the topic is registered in watsonx.data. Watsonx.data using the schema name of <span style="color:blue;background-color: transparent;">default</span> when registering a topic. The preferred name of the file should be <span style="color:blue;background-color:transparent;">&lt;schema&gt;&lt;table&gt;.json</span> but it is not a requirement. </p>
+<div class="admonition note">
+<p class="admonition-title">The following JSON file describes the contents of the Kafka topic being used in the Jupyter notebook example. Although the message descriptor has been created, the current version of watsonx.data does not use this information when displaying the data.</p>

If you don't see the service, you may need to refresh the screen to wait for Presto to become available. Clicking on the <span style="color:blue;background-color: transparent;">orders</span> table will display information about this topic.</p>

+<h1 id="milvus-console">Milvus Console</h1>
+<p>The Milvus vector database does not ship with a console in watsonx.data. If you want to use the supported console you will need to use these instructions to start up the Attu console. Details on the Milvus console (Attu) can be found at the <a href="https://github.com/zilliztech/attu">Github</a> site<sup style="color: blue;">1</code></sup>.</p>
+<p style="font-size: small;line-height: 0.4;"><sup>1. Thanks to Zineddine Gherari and Julien Pradier for help on getting the settings to work.</p>
+
+<h2 id="credentials-and-server-addresses">Credentials and Server Addresses</h2>
+<p>The Attu console requires the name or address of the server that will be running the console, along with the Milvus database. This value will be different for each user of this system. Gather the following information from your server reservation:</p>
+<ul>
+<li>Watsonx Server URL - This will be the URL at the beginning of all service addresses. For example: <code>useast.services.cloud.techzone.ibm.com</code>.</li>
+<li>Milvus External Port - The port number that the Milvus database is exposed to the outside world</li>
+<li>Attu External Port 1 - Open port #1 in the reservation. If you are using Open port #1, choose #2 instead.</li>
+<li>Attu Internal Port - Use 10000 for open port #1 or 10001 for open port #2</li>
+</ul>
+<p>Fill in the values in the next cell and execute it.</p>

+<p>Milvus is a vector database that stores, indexes, and manages massive embedding vectors that are developed by deep neural networks and other machine learning (ML) models. It is developed to empower embedding similarity search and AI applications. Milvus makes unstructured data search more accessible and consistent across various environments.</p>

+The server and port number will need to be substituted into the connection details below.</p>
+<h3 id="generate-the-connection-certificate_1">Generate the Connection Certificate</h3>
+<p>In addition to the server and port number, you will need to get the Certificate for the watsonx.server. You will need to download the contents of this file and place it into a file that is local to your Python application or Jupyter notebook server. The following command will retrieve the contents of the cert file and print the values. Copy all the text between <code>BEGIN CERTIFICATE</code> and <code>END CERTIFICATE</code> and place it into a local file with a name of <code>presto.crt</code>. Make sure to update the <code>server_pem_path</code> with your local file name.</p>
