Roshan Naik commented on STORM-2307:
------------------------------------
The plan is to have the executor thread itself do the intra-worker handoff. I
have a draft working code doing that.
But that does not require us to fuse the concepts of tasks and threads. Task
can continue to be a bolt/spout instance and Executor Thread can host multiple
tasks
My thought is to introduce a "ThreadLocalGropuing" as an alternative to
Local/ShuffleGrouping, which allows two Tasks to run within a single thread..
that way we don't need concurrent queue to move tuples between them.
