Subject [jira] [Commented] (HBASE-15082) Fix merge of MVCC and SequenceID performance regression
Date Fri, 08 Jan 2016 09:25:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15088953#comment-15088953
] 

stack commented on HBASE-15082:
-------------------------------

Get back our increment/append/checkAndPut perf. This fix is for master and for branch-1.2+.
HBASE-15031 did a narrow fix for versions before branch-1.2 where Increments were made consistent
unto themselves but if you did a concurrent Put to the Increment Cell, your results would
be indeterminate. This issue is about a fix that undoes the performance regression while keeping
row consistency whether an Increment is happening on a Cell or a Put/Delete, etc..
