nutcracker

Fast, light-weight proxy for memcached and Redis

nutcracker, also known as twemproxy (pronounced "two-em-proxy"), is a fast and lightweight proxy for the memcached and Redis protocols. It was primarily built to reduce the connection count on backend caching servers, but it has a number of features, such as: * Maintains persistent server connections to backend servers. * Enables pipelining of requests and responses. * Supports multiple server pools simultaneously. * Shard data automatically across multiple servers. * Supports multiple hashing modes including consistent hashing and distribution. * High-availability by disabling nodes on failures. * Observability through stats exposed on stats monitoring port.
