how to deal with connecton numbers between many server node? about protobuf-rpc-pro

so if i understand right, each server is connected to each other server, so 5x4 
connections == 20. Now the question of whether a bus ( multicast ) is 
appropriate or not depends on whether you really intend or need to distribute 
ALL messages between ALL servers ( and a bit on the location of these servers 
). In the end, you will only remain performant if you partition your data 
between available servers to provide a certain amount of redundancy, and 
unicast your data to the few appropriate servers.

There might be a "sweet" spot where multicast ( assuming in a single LAN / 
cloud provider ) is both efficient and fast for a dozen or so servers, but if 
you apply a reliable transport on top of UDP multicast, then you're overall 
sustainable throughput is limited by the message consumption rate of the 
slowest consumer(server).

If you partition your server data and only message to 2 or 3, the the absolute 
number of servers which a single server knows is hardly relavant. You can have 
TCP connections to hundreds of other servers without having problems. You have 
to consider your LAN/WAN setup and network topology to get really high 
performance ( and then you will need to know if you are trying to optimize 
throughput or latency ).
