This patch introduces the Prefetch object which allows customizing prefetch operations. This enables things like filtering prefetched relations, calling select_related from a prefetched relation, or prefetching the same relation multiple times with different querysets. When a Prefetch instance specifies a to_attr argument, the result is stored in a list rather than a QuerySet. This has the fortunate consequence of being significantly faster. The preformance improvement is due to the fact that we save the costly creation of a QuerySet instance. Thanks @akaariai for the original patch and @bmispelon and @timgraham for the reviews. |
