Subject [jira] [Created] (OAK-2322) Compaction estimation includes all data segments
Date Fri, 05 Dec 2014 09:10:13 GMT
Alex Parvulescu created OAK-2322:

             Summary: Compaction estimation includes all data segments
                 Key: OAK-2322
                 URL: https://issues.apache.org/jira/browse/OAK-2322
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core, segmentmk
            Reporter: Alex Parvulescu
            Assignee: Alex Parvulescu

The original design of the compaction estimator was to only focus on binary segments when
computing the amount of garbage that can be collected.
This has a flaw when it runs on systems with external data stores configured as there will
be almost no binary segments and the estimation will always be _0_, no need for compaction.

The change to include all segments is not big, the _uuids_ bloomfilter is already initialized
with the total number of segments, and the segment collection already loads everything in
