> Can we consider changing the criteria API in 3.3 so that DISTINCT_ROOT_ENTITY is the default transformer?
> 10:28
> I remember that detecting "fetch" in HQL and applying this transformer is already on the list, right?
> 10:29
> or introduce config options for both APIs, so users can switch the default transformer
> 10:30
> also, verify this please: http://www.hibernate.org/117.html#A12

> 2:31
> we should try to detect if any fetches are present
> 2:31
> otherwise DISTINCT_ROOT_ENTITY presents unecessary overhead
> 2:31
> i dont recall such a discussion regarding that  feature in HQL
> 2:32
> another option is sorta like i'm planning in other areas: fallback to subselect fetching
