[jira] [Created] (BEAM-4240) Implement the limited set of portable primitives in the Java DirectRunner

Thomas Groh created BEAM-4240:
---------------------------------

             Summary: Implement the limited set of portable primitives in the Java DirectRunner
                 Key: BEAM-4240
                 URL: https://issues.apache.org/jira/browse/BEAM-4240
             Project: Beam
          Issue Type: New Feature
          Components: runner-direct
            Reporter: Thomas Groh
            Assignee: Thomas Groh


This is Flatten, Impulse, GroupByKeyOnly, GroupAlsoByWindow (for the implementation of the DirectRunner), and {{ExecutableStage}}

 

{{Flatten}} and {{Impulse}} are straightforwards. {{GroupByKeyOnly}} requires extracting the runner-implementation of the PCollection's {{KeyCoder}}, and {{GroupAlsoByWindow}} and {{ExecutableStage}} both have specific concerns and are tracked independently
