----------------------------------------
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.
