---------------------------------
Summary: 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
For the join if one side is small and other side is large, the shuffle overhead
is also very big. Due to the 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.
