Welcome to Facebook's MySQL 5.6 Repository!
Our repository and changes are based on top of MySQL 5.6 branch. We have added a number of significant features to our code.
MyRocks (MySQL on RocksDB)
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.
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.
