> Support AQE side shuffled hash join formula
> -------------------------------------------
>
> Key: SPARK-35282
> URL: https://issues.apache.org/jira/browse/SPARK-35282
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: XiDuo You
> Assignee: XiDuo You
> Priority: Major
> Fix For: 3.2.0
>
>
> Use AQE runtime statistics to decide if we can use shuffled hash join instead
> of sort merge join. Currently, the formula of shuffled hash join selection
> does not work due to the dymanic shuffle partition number.
>
> Add a new config `spark.sql.adaptive.maxShuffledHashJoinLocalMapThreshold` to
> decide if join can be converted to shuffled hash join safely.
