Subject [jira] Created: (HBASE-1410) compactions are not memory efficient
Date Tue, 12 May 2009 18:17:45 GMT
compactions are not memory efficient 

                 Key: HBASE-1410
                 URL: https://issues.apache.org/jira/browse/HBASE-1410
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
             Fix For: 0.20.0

Compactions read a lot of data into the heap. Prior to HBASE-1058 or successor issues, it
was possible to stack up hundreds if not thousands of flushes in a store. Eventually when
compaction is possible, no HRS has enough heap to commit for the compaction process and all
OOME as the region in question is (re)deployed.
