> Key: HDDS-13475
> URL: https://issues.apache.org/jira/browse/HDDS-13475
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ivan Andika
> Assignee: Chia-Chuan Ho
> Priority: Major
>
> See:
> https://github.com/facebook/rocksdb/wiki/Tuning-RocksDB-on-Spinning-Disks to
> tune RocksDB on spinning disks. This would be mostly catered to the container
> DB which is colocated on the DN data volume (which are usually on disk).
> We might need to tune the DBProfile.DISK as follows
> * Increase the block size: This might have memory overhead on the block cache
> * Set DBOptions#setSkipStatsUpdateOnDbOpen to true
> We need to have a performance benchmark to justify the tuning.
