Andrew Kyle Purtell resolved HBASE-9365.
----------------------------------------
Resolution: Won't Fix
> Optionally limit major compactions to off peak hours
> ----------------------------------------------------
>
> Key: HBASE-9365
> URL: https://issues.apache.org/jira/browse/HBASE-9365
> Project: HBase
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Priority: Major
>
> We already have off peak hours (where we set a more aggressive compaction
> ratio) and periodic major compactions.
> It would be nice if we could limit this to off peak hours as well.
> A major compaction can be triggered in three ways:
> # a periodic chore checking every ~3h (10.000.000ms) by default
> # a minor compaction promoted to major because the last major compaction was
> too long ago
> # a minor compaction promoted to major (at the HStore level), because it
> touched all HFiles anyway
> For case #1 and #2 we could could optionally return false from
> Store.isMajorCompaction(...) when we're not in the off peak window. Would
> have a new config option to enforce that only optionally.
> In case #3 we're compacting all files anyway, so not need to interfere with
> that.
> Thoughts?
