Subject [jira] [Created] (HBASE-10721) Parallelize execution of multi operations on RegionServer
Date Tue, 11 Mar 2014 18:17:47 GMT
Gary Helmling created HBASE-10721:
-------------------------------------

             Summary: Parallelize execution of multi operations on RegionServer
                 Key: HBASE-10721
                 URL: https://issues.apache.org/jira/browse/HBASE-10721
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Gary Helmling


In the context of HBASE-10169, we're adding the ability to batch Coprocessor endpoint calls
per regionserver, using the same batching that happens in the RegionServer.multi() calls.
 However, execution of each of the calls will still happen serially on each RegionServer.
 For Coprocessor endpoint calls, it might help to parallelize these, since each execution
could be of indeterminate length.

Since it may help to parallelize the Coprocessor endpoint invocations, it raises the question
of whether other operations handled in multi() calls should also be parallelized, or should
we just rely on macro-scale parallelization through the RPC handler threads?
