             Summary: Support AQE side shuffled hash join formula
                 Key: SPARK-35282
                 URL: https://issues.apache.org/jira/browse/SPARK-35282
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: ulysses you


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 is 
not worked due to the dymanic shuffle partition number.

 

Add a new config `spark.sql.adaptive.shuffledHashJoinLocalMapThreshold` to 
decide if join can be converted to shuffled hash join safely.
