Simple implementation of memcached protocol for both server and client side. Not meant to replace memcached, but just sample code of network programming with muduo. Server limits: - The memory management is not customized, just uses (tc)malloc. - It doesn't control the memory footprint - Unix domain socket is not supported - Only listen on one TCP port Server goals: - Pass as many feature tests as possible - Prefer simplicity over performance TODO: - incr/decr - UDP - Binary protocol - expiration - LRU
