… rewrite by partition rolled up mv (#36414) This is brought by #35562 When mv is partition rolled up mv, which is rolled up by date_trunc. If base table add new partition. if query rewrite successfully by the partition mv, the data will lost the new partition data. This pr fix this problem. For example as following: mv def is: CREATE MATERIALIZED VIEW roll_up_mv BUILD IMMEDIATE REFRESH AUTO ON MANUAL partition by (date_trunc(`col1`, 'month')) DISTRIBUTED BY RANDOM BUCKETS 2 PROPERTIES ('replication_num' = '1') AS select date_trunc(`l_shipdate`, 'day') as col1, l_shipdate, o_orderdate, l_partkey, l_suppkey, sum(o_totalprice) as sum_total from lineitem left join orders on lineitem.l_orderkey = orders.o_orderkey and l_shipdate = o_orderdate group by col1, l_shipdate, o_orderdate, l_partkey, l_suppkey; if run the insert comand insert into lineitem values (1, 2, 3, 4, 5.5, 6.5, 7.5, 8.5, 'o', 'k', '2023-11-21', '2023-11-21', '2023-11-21', 'a', 'b', 'yyyyyyyyy'); then run query as following, result will not return the 2023-11-21 partition data select date_trunc(`l_shipdate`, 'day') as col1, l_shipdate, o_orderdate, l_partkey, l_suppkey, sum(o_totalprice) as sum_total from lineitem left join orders on lineitem.l_orderkey = orders.o_orderkey and l_shipdate = o_orderdate group by col1, l_shipdate, o_orderdate, l_partkey, l_suppkey;
