Subject [jira] [Created] (IGNITE-4476) GridIoManger must always process messages asynchronously
Date Thu, 22 Dec 2016 10:28:58 GMT
Vladimir Ozerov created IGNITE-4476:
---------------------------------------

             Summary: GridIoManger must always process messages asynchronously
                 Key: IGNITE-4476
                 URL: https://issues.apache.org/jira/browse/IGNITE-4476
             Project: Ignite
          Issue Type: Task
          Components: general
    Affects Versions: 1.8
            Reporter: Vladimir Ozerov
             Fix For: 2.0


*Problem*
If message is to be sent to remote node, we just send it (surprise :-)). But if message is
to be sent to local node, we have a strange "optimization" - we process it synchronously in
the same thread. 
This is wrong as it easily leads to all kind of weird starvations and deadlocks.

*Solution*
Never ever process messages synchronously. For local node we should put message runnable into
appropriate thread pool and exit.
