[jira] [Created] (OAK-3812) Disable compaction gain estimation if compaction is paused

Michael Dürig created OAK-3812:
----------------------------------

             Summary: Disable compaction gain estimation if compaction is paused
                 Key: OAK-3812
                 URL: https://issues.apache.org/jira/browse/OAK-3812
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segmentmk
            Reporter: Michael Dürig
             Fix For: 1.4


I think we should disable compaction estimation when compaction is paused. Estimation interferes with the caches, wastes CPU and IO cycles and is not essential for Oak's operation when compaction is disabled. The only reason it was unconditionally enabled initially is to gather the respective information in production. I think this has turned out to be not too useful so it is safe to disable.
