Facebook created MyRocks, and it is now available in MariaDB. MyRocks is a space and write optimized storage engine built on top of RocksDB. The initial objective was to replace InnoDB with MyRocks in the users database (UDB), reducing the amount of storage space needed by half. It was a success, and now Facebook is trying to make it better and help increase adoption in other services. In this session, Yoshinori will explain how Facebook replaced InnoDB with MyRocks in UDB, and highlight the features being developed and planned for future releases of MyRocks.

In this session, I'll discuss how we migrated from InnoDB to MyRocks in production at Facebook, for both slave and master instances, without stopping services, losing data, or returning incorrect results. We created many features for easier migration, such as fast data loading, and a tool that confirms data and query correctness, and runs without affecting online service. I will share lessons learned from our initial migrations and the impact we have seen.
