[jira] [Created] (SAMZA-1221) Simplify MessageStreamImpl and OperatorSpec graphs and traversals

Prateek Maheshwari created SAMZA-1221:
-----------------------------------------

             Summary: Simplify MessageStreamImpl and OperatorSpec graphs and traversals
                 Key: SAMZA-1221
                 URL: https://issues.apache.org/jira/browse/SAMZA-1221
             Project: Samza
          Issue Type: Bug
            Reporter: Prateek Maheshwari
             Fix For: 0.13.0


Currently the logical operator DAG traversal is unnecessarily convoluted since it requires interacting with both MessageStreamImpls (which provides #getRegisteredOperatorSpecs) and OperatorSpecs (which provides #getNextStream). This would be cleaner if we separated these two graphs such that the framework tracks and interacts only with the OperatorSpecs graph, and the MessageStreamImpl graph is just a user-facing view of it.
