Summary: support local shuffling
Key: GEARPUMP-52
URL: https://issues.apache.org/jira/browse/GEARPUMP-52
Project: Apache Gearpump
Issue Type: New Feature
Components: streaming
Reporter: Manu Zhang
imported from [https://github.com/gearpump/gearpump/issues/1649].
Storm has a grouping strategy called LocalOrShuffleGrouping which will have
better performance than ShuffleGrouping in theory.
{quote}
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.
{quote}
This requires context information of tasks in the same Executor.
