Our repository and changes are based on top of MySQL 5.6 branch. We have added a number of significant features to our code.
RocksDB is a LSM database optimized for Flash storage. It uses much less space, and has a much smaller write volume (write amplification) with small read penalty compared to a B+ tree database implementation such as InnoDB. The Myrocks project adds a new storage engine into MySQL backed by RocksDB.
MyRocks Tutorial slides (at Percona Live 2016) are also available.
DocStore is a JSON-styled document database built using MySQL. At the foundation we are enhancing MySQL to support efficient storage and querying of document data.
New performance data and statistics information have been added to the InnoDB storage engine. Among them are new new Information Schema tables and additional slow query log data.
Support for features such as defragmentation and compression in InnoDB (some of which are already in WebscaleSQL).
