-------------------------------------
What will happen in this case? Will it use BNLJ?
> spark.sql.optimizeNullAwareAntiJoin should respect
> spark.sql.autoBroadcastJoinThreshold

> Key: SPARK-45846
> URL: https://issues.apache.org/jira/browse/SPARK-45846
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Chao Sun
> Priority: Major
> Labels: pull-request-available
>
> Normally broadcast join can be disabled when users set
> {{spark.sql.autoBroadcastJoinThreshold}} to -1. However this doesn't apply to
> {{spark.sql.optimizeNullAwareAntiJoin}}:
> {code}
> case j @ ExtractSingleColumnNullAwareAntiJoin(leftKeys, rightKeys) =>
> Seq(joins.BroadcastHashJoinExec(leftKeys, rightKeys, LeftAnti,
> BuildRight,
> None, planLater(j.left), planLater(j.right), isNullAwareAntiJoin =
> true))
> {code}
