## Proposed changes
when aggregate function roll up, we should check the qury and mv function
argument is equal
such as mv def and query sql as following, it should not rewrite success,
because the bitmap_union_basic field augument is
not equal to the `count(distinct case when o_shippriority > 10 and
o_orderkey IN (1, 3) then o_custkey else null end)` field in query
mv def:
> select l_shipdate, o_orderdate, l_partkey, l_suppkey,
sum(o_totalprice) as sum_total,
max(o_totalprice) as max_total,
min(o_totalprice) as min_total,
count(*) as count_all,
bitmap_union(to_bitmap(case when o_shippriority > 1 and
o_orderkey IN (1, 3) then o_custkey else null end)) as bitmap_union_basic
from lineitem
left join orders on lineitem.l_orderkey = orders.o_orderkey and
l_shipdate = o_orderdate
group by
l_shipdate,
o_orderdate,
l_partkey,
l_suppkey;
query sql:
> select t1.l_partkey, t1.l_suppkey, o_orderdate,
sum(o_totalprice),
max(o_totalprice),
min(o_totalprice),
count(*),
count(distinct case when o_shippriority > 10 and o_orderkey IN
(1, 3) then o_custkey else null end)
from (select * from lineitem where l_shipdate = '2023-12-11') t1
left join orders on t1.l_orderkey = orders.o_orderkey and
t1.l_shipdate = o_orderdate
group by
o_orderdate,
l_partkey,
l_suppkey;
