Szehon Ho created SPARK-48065:
---------------------------------
Summary: SPJ: allowJoinKeysSubsetOfPartitionKeys is too strict
Key: SPARK-48065
URL: https://issues.apache.org/jira/browse/SPARK-48065
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.4.3
Reporter: Szehon Ho
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.
