Subject [jira] Updated: (HBASE-1620) Need to use special StoreScanner constructor for major compactions (passed sf, no caching, etc)
Date Tue, 07 Jul 2009 18:10:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1620?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Gray updated HBASE-1620:
---------------------------------

    Status: Patch Available  (was: Open)

Also does not add to changed readers observer list.  We don't want to add newly flushed storefiles
midway through compaction.  In the future, we could snapshot  the memcache and include it
in the major compaction.  Would be a good way to help keep storefiles low.

Ready for commit.
