Andrew Kyle Purtell resolved HBASE-10721.
-----------------------------------------
Resolution: Not A Problem
> Parallelize execution of multi operations on RegionServer
> ---------------------------------------------------------
>
> Key: HBASE-10721
> URL: https://issues.apache.org/jira/browse/HBASE-10721
> Project: HBase
> Issue Type: Sub-task
> Components: regionserver
> Reporter: Gary Helmling
> Priority: Major
>
> 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?
