Otter is a high-performance in-memory caching library for Go based on adaptive W-TinyLFU eviction. It offers a configurable API with size-based eviction, time-based expiration, automatic loading, async refresh, write-through, and statistics.

Use cases

  • add a fast in-memory cache to a Go service
  • improve cache hit rates over LRU
  • cache with TTL expiration and size limits
  • automatically load and refresh cached entries
  • reduce memory overhead of caching in Go

When to choose

  • you need a high-throughput, high-hit-rate cache in Go
  • you want Caffeine-like caching features in Go
  • memory overhead matters at large cache capacities

When to avoid

  • you need a distributed or shared cache across processes
  • your project is not in Go
  • you need persistent caching
