[jira] Commented: (HBASE-3150) Allow some column to not write WALs

["Kannan Muthukkaruppan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-3150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978929#action_12978929 ] 

Kannan Muthukkaruppan commented on HBASE-3150:
----------------------------------------------

One workaround would be to use:

    Put.writeToWAL(false). 

Caveat: This wouldn't work for the case when you have a mix of column families in the Put, some of which you want to write to WAL and others you don't.

> We have this unique requirement where some column families hold data that is indexed from other existing column families. The index data is very large, and we end up writing these inserts into the WAL and then into the store files. In addition to taking more iops, this also slows down splitting files for recovery, etc.
> Creating this task to have an option to suppress WAL logging on a per CF basis.
