Hi, I have a question around the protocol support in memcached:
Is there any (good) reason for registering one port per protocol in memcached? We have the text protocol, the binary protocol, and yet other protocols are in the coming. Would it be better to listen on a single port per IP protocol (TCP or UDP) and dispatch subprotocol requests internally? We could e.g. let the first byte in a packet determine the subprotocol (text protocol reserves all lower-case ASCII letters...) and then dispatch the socket to the proper subprotocol handler.
I am afraid of the myriad of options that will be needed to configure a memcached server. It would be great if we only need one option per IP protocol. Besides, it will make it easier for us if we decide to register official IANA ports for memcached.
