We just noticed that at one time, 4 nodes were doing minor compaction together, each of them took 20~60 minutes. We're on 0.8.1, 6 nodes, RF5. This simultaneous compactions slowed down the whole cluster, we have local_quorum consistency level, therefore, dynamic_snitch is not helping us.
Aside from lower down the compaction thread priority, is there any other way to tell the cluster hold on doing this if other nodes are already compacting? Thanks, Hefeng
