[jira] [Created] (TEZ-1517) Avoid sending routed events via the AsyncDispatcher

Siddharth Seth created TEZ-1517:
-----------------------------------

             Summary: Avoid sending routed events via the AsyncDispatcher
                 Key: TEZ-1517
                 URL: https://issues.apache.org/jira/browse/TEZ-1517
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


Sending them via the queue ends up creating lots of unnecesaary objects (millions for a large job), as well as blocking the queue.

Eventually, event routing should be handed over to a separate thread - so that the asyncdispatcher is unblocked to continue operations like launching tasks, etc.
