Details

We recently discovered while investigating a performance issue that django-filter's MultipleChoiceFilter (and by extension ModelMultipleChoiceFilter) passes distinct=True by default. This introduces unnecessary overhead to the query in many cases: Typically, distinct=True is needed only for many-to-many relationships.
