Subject [jira] Commented: (HBASE-1563) incrementColumnValue does not write to WAL
Date Wed, 24 Jun 2009 01:53:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12723395#action_12723395

Andrew Purtell commented on HBASE-1563:

bq. We still satisfy the property of "Once the increment has returned successfully, it is
safe". This weird scenario would actually only happen in a case where the increment started
but never returned (so client should not assume it was successful anyways).

This makes sense to me.

> Incrementing never writes to the WAL.  Under failure scenarios, you will lose all increments
since the last flush.
> Do we want to expose the option to the client as to whether to write to WAL or not?
