Subject [jira] [Commented] (HBASE-17081) Flush the entire CompactingMemStore content to disk
Date Tue, 17 Jan 2017 18:32:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15826565#comment-15826565
] 

ramkrishna.s.vasudevan commented on HBASE-17081:
------------------------------------------------

One minor comment, in CompositeImmutableSegment  see if we can unify getSnapshotScanner and
getScanner by passing the corresponding readPt and order. Because both gets created on the
list of segments only?
[~ted_yu], [~saint.ack@gmail.com] any other comments before we commit this?

> Part of CompactingMemStore's memory is held by an active segment, and another part is
divided between immutable segments in the compacting pipeline. Upon flush-to-disk request
we want to flush all of it to disk, in contrast to flushing only tail of the compacting pipeline.
