+# Extract and Load Postgres ETL Processes
+
+This folder contains Terraform configurations for the Extract and Load ETL processes.
+These processes are designed to extract data from an RDS instance, load it into an S3 bucket, then process it using Kubernetes jobs and AWS Step functions.
+
+## ETL Workflow
+
+**Extract**: `Source RDS -> ECS Task -> S3 Bucket (Extract)`
+- Dumps data from the source RDS database in the source account using Extract ECS task
+- The dump is compressed and stored in an S3 bucket
+
+**Transform**: `S3 Bucket (Extract) -> Kubernetes Dispatcher -> Transform Job -> S3 Bucket (Load)`
+- A Kubernetes dispatcher monitors the S3 bucket for new dumps
+- Another Kubernetes job loads the dump, applies SQL transformations (I.e. removing PII), and writes the cleaned dump back to a target S3 bucket.
+
+**Load**: `S3 Bucket (Load) -> ECS Task -> Target RDS`
+- The cleaned dump is restored into the target RDS database using Load ECS tasks.
+
+## Modules
+
+We have `extract` and `load` modules that contain Terraform code for extracting RDS data, ECS tasks, Step Function for extraction and load process, S3 bucket definitions, IAM roles/policies for accessing S3, RDS, etc and shared variables across modules.
+
+AWS Services: RDS for source and target databases, S3 for intermediate storage, ECS for running extraction and loading tasks and Step Functions for orchestration.
+
+Kubernetes: Dispather to monitor S3 for changes and Jobs for data transformation
+
+Jenkins: Orchestrates the pipeline by triggering Step Functions, monitoring jobs and logging execution. Please refer to the `ccs-jenkins-jobs` repo for the [Postgres ETL job](https://jenkins-eks.techopsdev.com/job/digitalmarketplace-1.5/job/postgres-etl/).
+
+## Important Notes
+
+#### IAM policies
+
+1. ECR Repository Access: Grants access to the ECR repositories for different environments (Dev, SBX, Prod).
+
+  ```terraform
+  resources = [
+      "arn:aws:ecr:${var.aws_region}:473251818902:repository/${var.migrator_name}",   # Dev
+      "arn:aws:ecr:${var.aws_region}:473251818902:repository/${var.migrator_name}:*", # Dev
+      "arn:aws:ecr:${var.aws_region}:665505400356:repository/${var.migrator_name}",   # SBX
+      "arn:aws:ecr:${var.aws_region}:665505400356:repository/${var.migrator_name}:*", # SBX
+      "arn:aws:ecr:${var.aws_region}:974531504241:repository/${var.migrator_name}",   # Prod
+      "arn:aws:ecr:${var.aws_region}:974531504241:repository/${var.migrator_name}:*"  # Prod
+    ]
+  ```
+
+2. ECS Exec actions: Allows ECS exec actions for managing ECS tasks.
+
+  ```terraform
+  actions = [
+      "ssmmessages:OpenDataChannel",
+      "ssmmessages:OpenControlChannel",
+      "ssmmessages:CreateDataChannel",
+      "ssmmessages:CreateControlChannel"
+    ]
+  ```
+
+#### Step Functions
+Contains environment variables for container `pg_dump` within **Extract** ECS task.
+- `DUMP_FILENAME` is the filename for the database dump.
+- `EXECUTION_ID` is used to monitor the Kubernetes job in Postgres ETL Jenkins pipeline.
+- `LOAD_ENVIRONMENT` is used to provide an indication of the S3 bucket name that is successfully uploaded to S3 from RDS.
+
+```json
+{
+  "Name": "pg_dump",
+  "Environment": [
+    {
+      "Name": "DUMP_FILENAME",
+      "Value": "etl-dump"
+    },
+    {
+      "Name": "EXECUTION_ID",
+      "Value.$": "$$.Execution.Id"
+    },
+    {
+      "Name": "LOAD_ENVIRONMENT",
+      "Value.$": "$.LOAD_ENVIRONMENT"
+    }
+  ]
+}
+```
+Contains environment variables for container `pg_restore` within **Load** ECS task.
+- `LOAD_ENVIRONMENT` is the variable of the S3 bucket name that is successfully downloaded from S3 and load into RDS.
+
+```json
+{
+  "Name": "pg_restore",
+  "Environment": [
+    {
+      "Name": "LOAD_FILENAME",
+      "Value.$": "$.LOAD_FILENAME"
+    }
+  ]
+}
+```
+
+
+#### SQS in the `extract` module
+
+We have a SQS Queue service used for watching the S3 bucket in the Extract environment.
