Subject [jira] [Commented] (HBASE-14920) Compacting Memstore
Date Wed, 30 Mar 2016 18:29:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218533#comment-15218533
] 

Anoop Sam John commented on HBASE-14920:
----------------------------------------

So in memory flush will move the cur active segment  (CSLM) to the pipeline and a new active
segment (and so new CSLM) is created.   So in pipeline it is still CSLM only..  The in memory
compaction picks up segments from pipeline and make new compacted result.  Here Cells bytes
(key and value) might be copied to new MSLAB chunks   and there wont be CSLM any more. There
we will have Cell array with ref to cells  (in MSLAB chunks)
