--------------------------------------

             Summary: Implement a useful default Partitioner and/or Unifier for Keyed Windowed Operator
                 Key: APEXMALHAR-2165
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2165
             Project: Apache Apex Malhar
          Issue Type: Improvement
            Reporter: Siyuan Hua


Based on first discussion, we can have some default partitioner to partition KeyedWindowedOperator into different instance and the possible Unifier to unify the result together.

For a non-keyed windowed operator, on the high-level API level, we can translate transform to 2 operators one KeyedWindowedOperator with a specified PartitionKey(not logically partition key) connect with another WindowedOperator which do final accumulation. This will be tracked in another ticket
