ASF GitHub Bot updated SPARK-58330:
-----------------------------------
Labels: pull-request-available (was: )
> Prevent silent dropping of dynamic options on same table references in DML
> --------------------------------------------------------------------------
>
> Key: SPARK-58330
> URL: https://issues.apache.org/jira/browse/SPARK-58330
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.2.0
> Reporter: Anurag Mantripragada
> Priority: Major
> Labels: pull-request-available
>
> Spark supports a per-statement `WITH (key = value)` dynamic table options
> clause on DMLs. When a single statement references the same table more than
> once with different options, only the first-resolved reference's options are
> honored; the other reference's options are silently dropped.
> Examples (each drops one side's options):
> {{INSERT INTO t WITH (`write.split-size` = 10) SELECT * FROM t}}
> {{MERGE INTO t WITH (`write.split-size` = 10)}}
> {{USING t WITH (`split-size` = 5) s}}
> {{ON t.id = s.id}}
> {{WHEN MATCHED THEN UPDATE SET ...}}
> {{UPDATE t WITH (`write.split-size` = 10) SET ...}}
> {{WHERE id IN (SELECT id FROM t WITH (`split-size` = 5))}}
