XiDuo You created SPARK-36822:
---------------------------------
Summary: BroadcastNestedLoopJoinExec should use all condition
instead of non-equi condition
Key: SPARK-36822
URL: https://issues.apache.org/jira/browse/SPARK-36822
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: XiDuo You
At JoinSelection, with ExtractEquiJoinKeys, we use `nonEquiCond` as the join
condition. It's wrong since there should exist some equi condition.
{code:java}
Seq(joins.BroadcastNestedLoopJoinExec(
planLater(left), planLater(right), buildSide, joinType, nonEquiCond))
{code}
But it's should not be a bug, since we always use the smj as the default join
strategy for ExtractEquiJoinKeys.
