Cheng Su created SPARK-34593:
--------------------------------
Summary: Preserve broadcast nested loop join output partitioning
and ordering
Key: SPARK-34593
URL: https://issues.apache.org/jira/browse/SPARK-34593
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: Cheng Su
`BroadcastNestedLoopJoinExec` does not propagate `outputPartitioning` and
`outputOrdering` right now. But it can propagate the streamed side partitioning
and ordering when possible. This can help avoid shuffle and sort in later
stage, if there's join and aggregation in the query.
