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
