## Proposed changes
Not roll up when aggregate rewrite if roll up group by expr is uniform
Such as mv name is mv3_0, and def is:
```sql
CREATE MATERIALIZED VIEW mv3_0
BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 2
PROPERTIES ('replication_num' = '1')
AS
select
o_orderdate,
o_shippriority,
o_comment,
sum(o_totalprice) as sum_total,
max(o_totalprice) as max_total,
min(o_totalprice) as min_total,
count(*) as count_all
from
orders
group by
o_orderdate,
o_shippriority,
o_comment;
```
query sql is as following:
```sql
select
o_comment,
sum(o_totalprice),
max(o_totalprice),
min(o_totalprice),
count(*)
from
orders
where
o_orderdate = '2023-12-09'
and o_shippriority = 1
group by
o_comment;
```
after rewrite the plan is as following, not need to add aggregate
```
PhysicalResultSink
--filter((mv3_0.o_orderdate = '2023-12-09') and (mv3_0.o_shippriority = 1))
----PhysicalOlapScan[mv3_0]
```
