Liang Xie commented on HBASE-9528:
----------------------------------
yeh, both "central planning compaction" and "compaction scheduler" seems more
suitable:)
> Adaptive compaction

> Key: HBASE-9528
> URL: https://issues.apache.org/jira/browse/HBASE-9528
> Project: HBase
> Issue Type: Sub-task
> Affects Versions: 0.98.0
> Reporter: Liang Xie
>
> 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.
> comments? thanks
