Subject [jira] [Updated] (OAK-3133) Make compaction map more efficient for offline compaction
Date Wed, 05 Aug 2015 14:02:05 GMT

     [ https://issues.apache.org/jira/browse/OAK-3133?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Dürig updated OAK-3133:
-------------------------------
    Description: The compaction map might be expensive. See OAK-2862 for the analysis. We
should find ways to lower the impact of this on offline compaction. One option would be to
make the compress cycle configurable, which would require more heap. Another option would
be to leverage the persisted compaction map here also.  (was: The compaction map might be
expensive. See )
