Memcached

memcached is a Memcached server made in Node.js.

Interesting bits .

The cache I ended up using, uses timeouts to expire the key value pair in the LRU

You can swap the cache its using in few steps by adding a new cache in src/caches/ see node-lru-cache.js for example

protocol

This memcached is based in the protocol present in https://github.com/memcached/memcached/blob/master/doc/protocol.txt
