--------------------------------

             Summary: 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


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}
