[jira] [Created] (SPARK-32421) Add code-gen for shuffled hash join

Cheng Su created SPARK-32421:
--------------------------------

             Summary: Add code-gen for shuffled hash join
                 Key: SPARK-32421
                 URL: https://issues.apache.org/jira/browse/SPARK-32421
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Cheng Su


We added shuffled hash join codegen internally in our fork, and seeing obvious improvement in benchmark compared to current non-codegen code path. Creating this Jira to add this support. Shuffled hash join codegen is very similar to broadcast hash join codegen. So this is a simple change.
