Django QuerySet Iteration

For iterating over large Django QuerySets, use iterate_queryset() from core.utils.iterators instead of .iterator():

from core.utils.iterators import iterate_queryset

# Good
for obj in iterate_queryset(queryset):
    process(obj)

# Avoid
for obj in queryset.iterator():
    process(obj)

Note: iterate_queryset() doesn't preserve ordering - if order matters, don't use it.
