Vladimir Rodionov commented on HBASE-9528:
------------------------------------------

Is it possible to create umbrella ticket for all compaction-relate JIRAs? New feature JIRA
- not a bug JIRAs?

> Currently, the compaction policy granularity is based on single machine. we had a thought
that introduce a new cluster granularity decision, such that we could improve those case per
cluster running status:
> 1) many nodes are compacting aggressive, we call it cluster compaction storm, we should
throttle it.
> 2) do more compaction if low traffic in current cluster(similar with off-peak feature),
not limit by config timerange(like off-peak timerange), just trigger by load or qps or other
stuff.
