[hibernate-dev] Query#iterate

[Christian Beikov]

I just know of people that are using iterate() now for efficient 
incremental processing, but I guess any other approach(streams maybe?) 
to do incremental processing would be good enough for these users.

Unfortunately I don't know what a shallow query is or what the 
implication on the query or the processing of being shallow are.
I guess this has to do with how row processing is done? I can imagine 
that this complicates the implementation, but really, there are users 
out there which rely on the performance model of that.
