[jira] [Commented] (HBASE-5108) CheckAndPut, CheckAndDelete, and ICV put memstore before writing WAL first -- by default

    [ https://issues.apache.org/jira/browse/HBASE-5108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13177552#comment-13177552 ]

--------------------------------------

When I wrote that paragraph I had ICV in mind. Sorry about the confusion. checkAnd* do the right thing.

> I thought it was just ICV that did the memstore put first.  This issue is about making it so the described behavior is optional and that the default out of the box goes for correctness -- i.e. write WAL first and then memstore.
