I am developing a system that will provide many services, say, S1, S2, S3. Each of these services have a number of executables that will communicate using events, using protobuf.

My question is: Which one do you think is better design: (1) Combine all events for all the services (currently about 10-15) into one big my_events.proto definition, or (2) Keep them separate, i.e. s1_proto, s2_proto, etc.

Nice thing about (1) is that there’s one proto file to worry about; downside is I’m linking the same large header file for all code.

Thanks!

    I’d go with separate definition files. If anything, because you can change each service individually without having to recompile/build the entire set; you can manage change histories better in CVS or whichever source code control tool you use; and it would perhaps be easier to lookup smaller files when you are working on the service implementations.
