We're currently looking at using protobuf for communication between a number of clients (java and iPhone) and a java server but I'm a bit confused how to best implement our protocol.
Our protocol consists of a big number of possible messages but I can't seem to find a way for protobuf to help me decide which message was sent. Writing and parsing messages is really easy when I know what exact message is being sent but this will never be the case in our application. We could write a field first in the message with some identifier of what message type is being sent but this feels to me like something a protocol tool should solve. If we have to go down that route what would be a good identifier? Is the index of the messages descriptor good enough or do I have to define it in the proto-file somehow? I guess these are very simple questions but I've been trying to find the answers in the documentation and at least I can't find it. Maybe add an example of how to handle multiple possible messages, the current Address Book example feels a little too basic.
