Subject [jira] [Created] (GEARPUMP-52) support local shuffling
Date Wed, 20 Apr 2016 05:34:25 GMT
Manu Zhang created GEARPUMP-52:

             Summary: support local shuffling
                 Key: GEARPUMP-52
             Project: Apache Gearpump
          Issue Type: New Feature
          Components: streaming
            Reporter: Manu Zhang

imported from [].

Storm has a grouping strategy called LocalOrShuffleGrouping which will have better performance
than ShuffleGrouping in theory.

Local or shuffle grouping: If the target bolt has one or more tasks in the same worker process,
tuples will be shuffled to just those in-process tasks. Otherwise, this acts like a normal
shuffle grouping.

This requires context information of tasks in the same Executor.
