    What's a good datastore for persistent distributed (i.e. no SPoF) *atomic* counters? (i.e. CP on the CAP triangle) Zookeeper?

        @bascule One thing mongo has is atomic operations on nested data structures. That _is_ nice.

        @KirinDave saw a lot of talk at RICON about that (eventually consistent atomic batch operations). Namely the "ACID 2.0" lightning talk

        @bascule if you have MySQL already we use a cool multirow counter solution

        @bascule How many clients are there? If not too many, keep each client under its own key in ZK, then counter value is the sum

        @martinkl probably about 50, but potentially more

        @bascule Sounds like each client keeping its own count would be just about feasible (and probably less painful than a distributed lock)

        @bascule Zookeeper does a good job. Mongo too, I guess (modulo your trust).
