Description of problem: [RFE] Changing BlueStore OSD rocksdb_cahce_size default value to 512MB for helping in compaction Version-Release number of selected component (if applicable): RHCS 3.2
The current default value is 128MB.
commit 8ff3c083ecc82345bbeb0b33d28408f9a95e5b1a Author: Sage Weil <sage> Date: Mon Sep 24 09:21:20 2018 -0500 rocksdb: increase default cache size to 512 MB For filestore OSDs, this is probably a good idea anyway, and is generally not going to be hugely impactful on the memory footprint (where users have been told to provide 1 GB RAM per 1 TB storage for a long time now). For bluestore OSDs, this value is meaningless as we're autotuning this anyway. For mons, this is a more reasonable default.
