Review Comment:
maybe you can use `order by a` to make the result stable.
```sql
select a,
rank() over (partition by 10, a, 'a', null order by 20, a, 10, 'a',
null) rnk,
row_number() over (partition by 10, a, 'a', null order by 20, a, 10,
'a', null) rn
from (select 2 a union all select 1 a) q order by a;
```
