Mcrouter is a memcached protocol router developed by Facebook for scaling memcached deployments, handling nearly 5 billion requests per second at peak in production. It provides flexible routing, sharding, replication, failover, and multi-cluster support while speaking the memcached ASCII protocol.
Use cases
- scale memcached across many servers
- route cache requests by key prefix
- add automatic failover to a memcached fleet
- shadow production traffic to test a new cache tier
- set up multi-level caches with warm-up
- run a multi-cluster memcached setup
- broadcast cache invalidations reliably
When to choose
- you run memcached at large scale and need sharding, replication, or failover
- you need prefix routing or multi-cluster cache topologies
- you want battle-tested infrastructure proven at Facebook/Instagram scale
When to avoid
- you use Redis or another cache instead of memcached
- you have only one or two memcached servers and simple needs
- you need a managed solution rather than self-operated C++ software
- you need Windows or macOS support - it targets Linux
