+twemproxy
+=========
+
+[twemproxy][1] (pronounced "two-em-proxy"), aka nutcracker is a fast and
+lightweight proxy for memcached and redis protocol. It was built primarily to
+reduce the number of connections to the caching servers on the backend. This,
+together with protocol pipelining and sharding enables you to horizontally
+scale your distributed caching architecture.
+
+## up and running
+
+```bash
+$ docker-compose up -d
+
+$ docker-compose exec redis redis-cli -h twemproxy
+twemproxy:6379> ping
+PONG
+twemproxy:6379> set hello world
+OK
+twemproxy:6379> get hello
+"world"
+twemproxy:6379> del hello
+(integer) 1

+$ tail -f data/twemproxy/logs/nutcracker.log
