Subject [jira] [Created] (HBASE-4231) Flush regions in multiple threads
Date Fri, 19 Aug 2011 09:16:27 GMT
Flush regions in multiple threads
---------------------------------

                 Key: HBASE-4231
                 URL: https://issues.apache.org/jira/browse/HBASE-4231
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.94.0
            Reporter: Todd Lipcon
             Fix For: 0.94.0


As servers get beefier, it makes less and less sense to have only a single thread do flushes
at a time. In watching an insert-only benchmark run, HBase isn't currently disk, network,
or CPU-bound -- it seems it's bound only by the rate at which flushes and compactions get
processed. Increasing the threading a bit here should increase total disk/network throughput
utilization.
