[jira] [Created] (SAMZA-1974) Optimize partitionBy() for task count =1

Xinyu Liu created SAMZA-1974:
--------------------------------

             Summary: Optimize partitionBy() for task count =1
                 Key: SAMZA-1974
                 URL: https://issues.apache.org/jira/browse/SAMZA-1974
             Project: Samza
          Issue Type: Improvement
            Reporter: Xinyu Liu
            Assignee: Xinyu Liu


We don't need to create intermediate streams to do repartition if the task count is 1. In this case, all the keys will be mapped to a single task so no need to repartition anymore.
