Ceph

Hi, Sage Weil, i suggest using RPC to replace previous network. RPC just focus on business not the network details, and RPC is very easy to use, i think using RPC will improve the development efficiency and make things much more easier.
Here is my RPC framework--rest_rpc https://github.com/topcpporg/rest_rpc , it's developed with c++14, very easy to use, and also the performance is excellent(qps can reach 460,000).rest_rpc is not just surpport RPC call, but alse surpport pub/sub pattern.
Maybe you can try it, and i can do some effert to apply rest_rpc to ceph.

Welcome someone esle discuss this suggestion.
