Subject [jira] Commented: (HBASE-1058) Prevent runaway compactions
Date Tue, 14 Apr 2009 21:35:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12698947#action_12698947

Jean-Daniel Cryans commented on HBASE-1058:

Stack, I'm really talking about CompactionLimitThread. This is the functionality that limits
the number of files that can be compacted at the same time at startup. Playing with this when
a region gets a lot of writes, we could lower the compaction time, but it would happen more
often. A way to "soften" things up.

we can compact them up.  Fix.
