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.
