EventedCache is an eventmachine based memcache client. It should be ultrafast and scalable since it leverages the power of ragel to parse memcache protocol and the scalability of eventmachine.

EM.run{

connect to memcached

cache = EventedCache.connect('localhost', 11211)

set a value that expires in 1 second

cache.set('key', 'hello!', 1)

read the value

cache.get('key'){ |val| # val.data == 'hello!' puts val.data }

wait for it to expire and read it again

EM.add_timer(2){ cache.get('key'){ |val| # val == nil puts val } }

}
