MyRocks Deep Dive
This is a tutorial about MyRocks: RocksDB Storage Engine for MySQL (https://github.com/facebook/mysql-5.6). MyRocks is a project to utilize space and write optimized LSM database with MySQL. MyRocks supports lots of useful features like below. - Less than half space compared to compressed InnoDB - Much smaller write amplification compared to InnoDB - Reverse order index so that descending scan can be a lot faster - Crash safe slave and master - Maitaining optimizer statistics without index dive - Built-in online backup tool - PostgreSQL-style transaction isolation support (Read Committed and Repeatable Read) - Efficient lookup and prefix seek with bloom filter MyRocks is a fully open source database. Supplemental tools, such as online backup tool, are also open sourced. At Facebook, we deployed MyRocks in production in 2016, and are increasing usage. In this 3-hour tutorial, the speaker will give MyRocks and RocksDB deep dive talk. The following topics will be covered. - What is RocksDB - Differences between B+Tree and LSM - MyRocks advantages over InnoDB - MyRocks limitations - Installing MyRocks on Linux machine - Schema design and column families - Configurations - Performance tuning - Backup and recovery - Use cases at Facebook Minimum technical requirements for attendees are basic understanding of InnoDB and MySQL Replication.
