[jira] [Comment Edited] (OAK-3133) Make compaction map more
efficient for offline compaction
[ https://issues.apache.org/jira/browse/OAK-3133?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14736592#comment-14736592 ]

---------------------------------------------------------------
proposed patch for filtering out node states during offline compaction (also includes patch from OAK-3379).
when backporting to 1.0 this also needs Francesco's patch to read the _compress-interval_ out of system properties.

> 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.
