Greater Space Efficiency
MyRocks has 2x better compression compared to compressed InnoDB, 3-4x better compression compared to uncompressed InnoDB, meaning you use less space.
Greater Writing Efficiency
MyRocks has a 10x less write amplification compared to InnoDB, giving you better endurance of flash storage and improving overall throughput.
No random reads for updating secondary keys, except for unique indexes. The Read-Free Replication option does away with random reads when updating primary keys, regardless of uniqueness, with a row-based binary logging format.
Faster Data Loading
MyRocks writes data directly onto the bottommost level, which avoids all compaction overheads when you enable faster data loading for a session.
