Subject [jira] [Commented] (HBASE-16421) Introducing the CellChunkMap as a new additional index variant in the MemStore
Date Wed, 02 Nov 2016 14:01:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15629057#comment-15629057
] 

stack commented on HBASE-16421:
-------------------------------

For large Cells, should be onheap because allocation of one-offs offheap will be too expensive.

Move to own module so easier to work on, test, and perf eval? (St.Ack to look at this)

Turn on MSLAB always so one way of getting at Cells.

What to do about Increments and Appends? Increments and Appends good candidates for flattening.
