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
}
}
}
