Welcome to Facebook's MySQL 5.6 Repository!

Our repository is based on WebscaleSQL's 5.6 branch. We have added a number of significant features to our code.

MyRocks (MySQL on RocksDB)

RocksDB is LSM database and well optimized on Flash storage -- much smaller space, much smaller write volume (write amplification) with small read penalty compared to a B+ tree implementation such as InnoDB. The MyRocks project adds a new storage engine into MySQL using RocksDB.

DocStore

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.
