Purpose

Currently paimon delete where supports directly dropping partitions when all filters are partition filter. Therefore we can not allow partial success for this filter conversion.

CREATE TABLE T (id INT, p STRING) PARTITIONED BY (p);
INSERT INTO T VALUES (2, '2024-12-16'), (3, '2024-12-17'), (4, '2024-12-18');
DELETE FROM T WHERE p >= date_sub('2024-12-17', 0) AND p < '2024-12-18';
SELECT * FROM T ORDER BY id;

before

+---+----------+
| id|         p|
+---+----------+
|  4|2024-12-18|
+---+----------+

after

+---+----------+
| id|         p|
+---+----------+
|  2|2024-12-16|
|  4|2024-12-18|
+---+----------+
