XiDuo You updated SPARK-40354:
------------------------------
Description:
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}
