Apache Spark reassigned SPARK-36823:
------------------------------------
Assignee: Apache Spark
> Support broadcast nested loop join hint for equi-join
> -----------------------------------------------------
>
> Key: SPARK-36823
> URL: https://issues.apache.org/jira/browse/SPARK-36823
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: XiDuo You
> Assignee: Apache Spark
> Priority: Major
>
> For the join if one side is small and other side is large, the shuffle
> overhead is also very big. Due to the
> bhj limitation, we can only broadcast right side for left join and left side
> for right join. So for the other case, we can try to use
> `BroadcastNestedLoopJoin` as the join strategy.
