# Rationale for this change
Optimized of In_List clause, when all filter values of In clause are static.
Default list values use `Vec` to store, it has time complexity O(n) to
check `contains`, In some situation use `Set` it has complexity O(1)

```select count(*) from orders where o_orderkey in (2785313,
2785314,
2785315,
2785316,
''' (1000 elements)
2786311);
```
