Mcrouter (pronounced mc router) is a memcached protocol router for scaling memcached deployments. It's a core component of cache infrastructure at Facebook and Instagram where mcrouter handles almost 5 billion requests per second at peak.
Mcrouter is developed and maintained by Facebook.
See https://github.com/facebook/mcrouter/wiki to get started.
See INSTALL.md
See https://github.com/facebook/mcrouter/wiki/mcrouter-installation for more detailed installation instructions.
Mcrouter depends on folly, wangle, fizz, and fbthrift.
The installation is a standard autotools flow:
$ autoreconf --install
$ ./configure
$ make
$ sudo make install
$ mcrouter --help
Assuming you have a memcached instance on the local host running on port 5001, the simplest mcrouter setup is:
$ mcrouter \
--config-str='{"pools":{"A":{"servers":["127.0.0.1:5001"]}},
"route":"PoolRoute|A"}' \
-p 5000
$ echo -ne "get key\r\n" | nc 0 5000
(nc is the GNU Netcat, https://netcat.sourceforge.net/)
