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:

       o      Maintains persistent server connections to backend servers.

       o      Enables pipelining of requests and responses.

       o      Supports multiple server pools simultaneously.

       o      Shard data automatically across multiple servers.

       o      Supports multiple hashing modes including consistent hashing and
              distribution.

       o      High-availability by disabling nodes on failures.

       o      Observability through stats exposed on stats monitoring port.
