Summary

Mcrouter (pronounced mc router) is a memcached protocol router for scaling

memcached deployments.

Because the routing and feature logic are abstracted from the client in

mcrouter deployments, the client may simply communicate with destination

hosts through mcrouter over a TCP connection using standard memcached

protocol. Typically, little or no client modification is needed to use

mcrouter, which was designed to be a drop-in proxy between the client and

memcached hosts.
