NUTCRACKER(8) System Manager's Manual NUTCRACKER(8) NAME nutcracker - Fast, light-weight proxy for memcached and Redis SYNOPSIS nutcracker [options] DESCRIPTION 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.
