--- Comment #15 from Sean Pringle <> ---
16 partitions, a number chosen after some rough back-of-napkin style
calculations for the larger wikis.

The effect of accessing multiple partitions is closest to UNION. I don't
anticipate excessive sorting or limiting penalties for our other queries though
I do want to see how range access and index scans perform.

Monitoring for queries adversely affected is definitely necessary and one of
the reasons for only partitioning one slave per shard.
