Lars Hofhansl created HBASE-9365: ------------------------------------ Summary: 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
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.
