Using server side cursors for values and values_list

[Dražen Odobašić]

Hi,

at the moment `chunked_fetch` (server side cursors) are only initialized for
ModelIterable class. Is there any reason why we should not do the same for other
BaseIterable classes (ValuesIterable, ValuesListIterable and
FlatValuesListIterable).

The idea is that you could then use QuerySet.values_list('id').iterator() and
actually use server side cursors.

I can't think of any reasons why not to do this off the top of my head. Have you looked into the code? Is there any technical reason you can see that might prevent chunked fetching from working there?

Hi,

the change seems relatively simple: https://code.djangoproject.com/ticket/28817,
and it does not break any existing tests.
