Pelikan is Twitter's framework for building high-performance cache services, written in Rust with a legacy C codebase. It includes products like Segcache, a Memcached-compatible server with high memory efficiency and predictable low latency.
Use cases
- run a memcached-compatible cache server with better memory efficiency
- deploy a low-latency caching backend at large scale
- build a custom cache service on a modular framework
- proxy memcache clients to Momento
- measure baseline RPC performance with a ping server
When to choose
- you need a high-throughput, low-latency cache backend for large-scale deployment
- you want extremely memory-efficient caching like Segcache
- you are developing new caching protocols or services and want reusable components
When to avoid
- you need a general-purpose database with persistence
- you want a turnkey managed cache without operating servers
- you rely on the legacy C codebase for new production deployments
