Subject [jira] [Created] (BEAM-956) Execute ReduceFnRunner Directly in Flink Runner
Date Thu, 10 Nov 2016 10:27:59 GMT
Aljoscha Krettek created BEAM-956:
-------------------------------------

             Summary: Execute ReduceFnRunner Directly in Flink Runner
                 Key: BEAM-956
                 URL: https://issues.apache.org/jira/browse/BEAM-956
             Project: Beam
          Issue Type: Improvement
          Components: runner-flink
            Reporter: Aljoscha Krettek


Right now, a {{ReduceFnRunner}} is executed via {{GroupAlsoByWindowViaWindowSetDoFn}} which
in turn is executed via a {{DoFnRunner}}. We should change that to get rid of the dependence
on {{GroupAlsoByWindowViaWindowSetDoFn}} which is an {{OldDoFn}} and also to get rid of some
unneeded layering.
