[Cloud] Counting edits by namespace and revision_actor_temp

Hi. I'm doing a secret project 😉 for a presentation. I want to count edits per namespace up until certain date. There are about ~200 users so not that much, but too many to do via edit counter... Using revision_actor_temp I get results much(!) faster, but I get a different namespace (2 instead of 0). https://quarry.wmflabs.org/query/41072 Longer query, but correct results: https://quarry.wmflabs.org/query/24267 Is this a bug or a feature? 😉 Cheers, Nux.
