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
