Cheng Su updated SPARK-34705:
-----------------------------
Issue Type: Umbrella (was: Improvement)
> Add code-gen for all join types of sort merge join
> --------------------------------------------------
>
> Key: SPARK-34705
> URL: https://issues.apache.org/jira/browse/SPARK-34705
> Project: Spark
> Issue Type: Umbrella
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Cheng Su
> Priority: Minor
>
> Currently sort merge join only supports inner join type
> ([https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/SortMergeJoinExec.scala#L374]
> ). We added code-gen for other join types internally in our fork and saw
> obvious CPU performance improvement. Create this Jira to propose to merge
> back to upstream.
