Twemproxy (nutcracker) is a fast, lightweight proxy for the memcached and Redis protocols, written in C. It reduces backend connection counts and enables horizontal scaling of caching tiers through sharding, pipelining, and consistent hashing.

Use cases

• shard redis across multiple servers
• reduce connection count to memcached backends
• scale a distributed cache horizontally
• proxy redis requests with consistent hashing
• pipeline memcached requests through a single endpoint
• disable failing cache nodes automatically

When to choose

• you need a battle-tested, lightweight C proxy for memcached or Redis protocols
• you want automatic sharding with consistent hashing across cache servers
• backend caching servers are overwhelmed by too many client connections

When to avoid

• you need Redis Cluster features like multi-key operations across shards or replication-aware routing
• you want an actively developed proxy with modern Redis support (consider predixy or envoy instead)
• you need TLS termination or rich observability
