feiniaofeiafei opened a new pull request, #42199:
URL: https://github.com/apache/doris/pull/42199
this pr do 2 things:
1.support pull up predicates from aggregate min/max/avg. e.g.
```sql
select * from (select avg(c) c1 from test_like1 where c<=10 group by a ) t
inner join test_like2 t2 on t.c1=t2.a;
```
c<=10 pull up from aggregate to avg(c)<=10, and then pull up from aggregate
to t.c1<=10, and with equal join condition,can infer predicate t2.a<=10.
2. carry qualifier when pull up from projects, before this pr, c1<=10 pull
up from project to c1<=10. after this pr, c1<=10 pull up from project to
t.c1<=10.
