This presentation sheds light on an essential tuning enhancement in Ceph, specifically Bluestore RocksDB compression, now enabled by default in versions Reef and above. Through this presentation, our aim is to familiarize the broader audience with rocksDB compression’s significance, advantages, and usage in Ceph, particularly in hybrid
deployments where NVMe drives store WAL/DB data.

By exercising this optimization, we achieve nearly identical performance while considerably reducing space utilization for storing metadata.

In addition to explaining rocksDB compression, we will delve into the testing workflow employed during the performance evaluation, we emphasize on the methodologies deployed and the performance of Ceph under different sets of workloads with and without fault insertion.
