Subject Avoid Simultaneous Minor Compactions?
Date Mon, 22 Aug 2011 05:22:25 GMT
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?
