Facebook's fork of Oracle MySQL 5.6 that includes the MyRocks storage engine, which uses RocksDB as the backend storage instead of InnoDB. It offers better compression, lower write amplification, and faster replication for flash-based storage workloads.

Use cases

• run mysql with rocksdb storage engine
• reduce database storage footprint with better compression
• lower write amplification for flash storage endurance
• speed up mysql replication with read-free secondary key updates
• bulk load data faster without compaction overhead
• self-host a mysql-compatible database tuned for ssd workloads

When to choose

• you need mysql compatibility but want RocksDB's space and write efficiency
• your workload is write-heavy on flash storage and InnoDB write amplification is a bottleneck
• you want faster replication with less random I/O for secondary indexes

When to avoid

• you need a modern MySQL version with current features and security patches, since this is based on MySQL 5.6
• you rely on InnoDB-specific features or tooling
• you want a database with broad platform support beyond the officially verified Linux distributions
