[jira] [Created] (SAMZA-1292) Merge operator can be no-op when no streams to merge

Prateek Maheshwari created SAMZA-1292:
-----------------------------------------

             Summary: Merge operator can be no-op when no streams to merge
                 Key: SAMZA-1292
                 URL: https://issues.apache.org/jira/browse/SAMZA-1292
             Project: Samza
          Issue Type: Bug
            Reporter: Prateek Maheshwari
            Assignee: Prateek Maheshwari
            Priority: Minor
             Fix For: 0.14.0


Currently MessageStream#merge(Collection) creates a merge operator even when the collection of streams to merge with is empty. Can just return current MessageStream in this case as an optimization.
