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