> Support eliminate dynamic partition for v1 writes
> -------------------------------------------------
>
> Key: SPARK-40354
> URL: https://issues.apache.org/jira/browse/SPARK-40354
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: XiDuo You
> Priority: Major
>
> v1 writes will add an extra sort for dynamic columns, e.g.
> {code:java}
> INSERT INTO TABLE t1 PARTITION(p)
> SELECT c1, c2, 'a' as p FROM t2 {code}
> if the dynamic columns are foldable, we can optimize it to:
> {code:java}
> INSERT INTO TABLE t1 PARTITION(p='a')
> SELECT c1, c2 FROM t2 {code}
