             Summary: 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


v1 writes will add a 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}
