Subject [jira] Commented: (HBASE-3149) Make flush decisions per column family
Date Wed, 19 Jan 2011 03:40:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12983523#action_12983523

Nicolas Spiegelberg commented on HBASE-3149:
--------------------------------------------

@ryan: the main work in step #3 isn't HBASE-2856 work.  It's roughly modifying HLog.lastSeqWritten
from Map<region, long> => Map<store, long> and all the refactoring to the HLog
code that it entails.

> Today, the flush decision is made using the aggregate size of all column families. When
large and small column families co-exist, this causes many small flushes of the smaller CF.
We need to make per-CF flush decisions.
