--------------------------------
Summary: 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: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: Cheng Su
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.
