Subject [jira] Resolved: (HBASE-1058) Prevent runaway compactions
Date Wed, 20 May 2009 23:29:45 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1058?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Purtell resolved HBASE-1058.

       Resolution: Later
    Fix Version/s:     (was: 0.19.2)
                       (was: 0.20.0)
     Hadoop Flags:   (was: [Reviewed])

Up on IRC it was decided to re-resolve this issue as Later. More investigation is needed as
to why compactions cannot keep up under high write load. The gating band aid in memcache flusher
hurts upload performance.

we can compact them up.  Fix.
