Subject [jira] [Commented] (HBASE-12669) Have compaction scanner save info about delete markers
Date Mon, 29 Dec 2014 09:22:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14259963#comment-14259963

ramkrishna.s.vasudevan commented on HBASE-12669:

The approach looks good to me using the scan type to track the delete trackers.  This would
not need any change in the scanquery matcher too. Not committing the del writer file if there
are no del trackers seems a good option too.

> for the native mob compaction, we will need a scanner pass used the major compaction
that records the delete markers in the mob-enabled columns.  This would implement that core
