Subject [jira] [Commented] (HBASE-16608) Introducing the ability to merge ImmutableSegments without copy-compaction or SQM usage
Date Sat, 10 Sep 2016 19:15:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15480277#comment-15480277
] 

Anastasia Braginsky commented on HBASE-16608:
---------------------------------------------

This is an incremental improvement toward appropriate in-memory flush policy in the CompactingMemStore.
As we learned, it is preferable to have smaller patches that are easier to review and commit.
This JIRA is opened as a continuation for HBASE-14921 and it is planned to be continued by
HBASE-16417.

Hereby, we present the merging of the ImmutableSegments of the CompactionPipeline and the
integration of this feature into entire flow. This is not meant to be the final solution of
the in-memory flush issue, just a step forward.
