Subject [jira] Commented: (HBASE-1563) incrementColumnValue does not write to WAL
Date Thu, 25 Jun 2009 13:34:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12724086#action_12724086

Irfan Mohammed commented on HBASE-1563:

Can we please ensure that the "atomic" puts are honored? 

I migrated lot of my code to use the incrementColumnValue() because of the atomic nature of
this call and it really reduces the data footprint and also the query time when aggregating
the cell values.

> 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?
