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.
