Chao Sun created SPARK-45846:
--------------------------------
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}
