---------------------------------
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}
