.BlueStore's RocksDB compression enabled
With this enhancement, to ensure that the metadata (especially OMAP) takes less space, RocksDB configuration is modified to enable internal compression of its data.
As a result,
- database size is smaller
- write amplification during compaction is smaller
- average I/O is higher
- CPU usage is higher
