Was going to post this. "Sharding" seems like a better term for communicating the idea.

I dunno - "sharding" would generally imply (to me, at least) that you're spreading the counters amongst different databases (or tables in a smaller context.) All the counters are in the same table here which is counterintuitive to "sharding".
