Subject [jira] [Commented] (HBASE-14921) Memory optimizations
Date Mon, 30 May 2016 11:54:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15306567#comment-15306567

Edward Bortnikov commented on HBASE-14921:
------------------------------------------

My 2 cents. 

The exact scope of the suggested (committable) patch would be: 
1. Adjusted Segment hierarchy and service classes - to accommodate new ImmutableSegment implementations.

2. CellArrayMap implementation. 
3. Flattening-without-compaction path - new scenario. 

This patch will already be sizable, that's why we're suggesting to focus on it first, and
isolate the treatment of CellChunkMap to a separate patch.
