> URL: https://issues.apache.org/jira/browse/SPARK-48065
> Project: Spark
> Issue Type: Sub-task

> Fix For: 4.0.0
>
>
> If spark.sql.v2.bucketing.allowJoinKeysSubsetOfPartitionKeys.enabled is true,
> then SPJ no longer triggers if there are more join keys than partition keys.
> It is triggered only if join keys is equal to , or less than, partition keys.
>
> We can relax this constraint, as this case was supported if the flag is not
> enabled.
