Percona MyRocks Introduction¶

MyRocks is a storage engine for MySQL based on RocksDB, an embeddable, persistent key-value store. Percona MyRocks is an implementation for Percona Server for MySQL.

The RocksDB store is based on the log-structured merge-tree (or LSM tree). It is optimized for fast storage and combines outstanding space and write efficiency with acceptable read performance. As a result, MyRocks has the following advantages compared to other storage engines, if your workload uses fast storage, such as SSD:

• Requires less storage space
• Provides more storage endurance
• Ensures better IO capacity
