sturdyc is a Go caching library focused on protecting I/O-heavy applications from cache stampedes through request coalescing, asynchronous refreshes, and inflight tracking. It provides non-blocking reads and sharded writes with fine-grained control over data freshness.

Use cases

• prevent cache stampedes in high-throughput services
• reduce load on databases and external APIs
• cache expensive function calls with async refresh
• coalesce duplicate concurrent requests for the same key
• add in-memory caching in front of distributed caches
• lower P95 latency for data-heavy endpoints

When to choose

• you build Go services with heavy I/O to databases, caches, or external APIs
• you need stampede protection and request coalescing out of the box
• you want granular control over cache freshness and background refreshes

When to avoid

• you need a distributed cache itself (sturdyc is an in-process layer, not a Redis/Memcached replacement)
• your application is not written in Go
• you only need simple key-value caching without concurrency features
