Could you elaborate more on how you have used Protobuffs, as I'm not sure I fully understand. I've previously used Riak in Erlang and Ruby projects, so am fairly familiar with how it works. It exposes a HTTP and Protobuffs API which allows you to store objects of arbitrary types (JSON, Erlang binary terms, Images, Word Documents, etc). From the sounds of it you are serialising a Protobuffs packet and sending this as the content of the object. Why did you choose this, over say JSON, which MongoDB uses?
