Subject [jira] Commented: (HBASE-1563) incrementColumnValue does not write to WAL
Date Mon, 22 Jun 2009 20:19:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12722796#action_12722796

ryan rawson commented on HBASE-1563:
------------------------------------

2 things:
- in the client code you build a 'get' that isnt used.
- we are writing to the WAL _after_ the increment, this may be the only way to do it effectively,
but we should also think about this carefully.

> 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?
