Sorabh Hamirwasia created DRILL-6446:
----------------------------------------

             Summary: Support for EMIT outcome in TopN
                 Key: DRILL-6446
                 URL: https://issues.apache.org/jira/browse/DRILL-6446
             Project: Apache Drill
          Issue Type: Task
          Components: Execution - Relational Operators
            Reporter: Sorabh Hamirwasia
            Assignee: Sorabh Hamirwasia
             Fix For: 1.14.0


With Lateral and Unnest if TopN is present in the sub-query, then it needs to handle the EMIT outcome correctly. This means when a EMIT is received then perform the TopN operation on the records buffered so far and produce output with it. After EMIT TopN should refresh it's state and again work on next batches of incoming record unless an EMIT is seen again.
