[jira] [Commented] (HBASE-15091) Forward-port to 1.2+ HBASE-15031 "Fix merge of MVCC and SequenceID performance regression in branch-1.0 for Increments"

    [ https://issues.apache.org/jira/browse/HBASE-15091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15135361#comment-15135361 ] 

stack commented on HBASE-15091:
-------------------------------

This forward port of the branch-1.1. patch was not necessary. This was identified over in HBASE-15213. HBase 1.2.0 does not suffer an increment performance regression (nor append, checkAnd*, etc.).  It did, but HBASE-12751 fixed it (unexpectedly).  I updated the release note.
