-----------------------------------

             Summary: Tar compaction: log a warning if there is more than one checkpoint
                 Key: OAK-2040
                 URL: https://issues.apache.org/jira/browse/OAK-2040
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core, segmentmk
            Reporter: Thomas Mueller
             Fix For: 1.0.5


Tar segment compaction usually can't shrink the repository if there are many checkpoints. Checkpoints can be cleaned up, but maybe somebody forgets about this, or possibly checkpoints can accumulate due to a bug.

Before running compaction, the segment node store should check how many checkpoints there are, and if there is more than one, it should log a warning. That way one can more easily analyze problems related to compaction.
