## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: caching, concurrency, middleware
- domain: backend, performance, developer-tools, microservices
- platform: go, cross-platform
- tags: cache-stampede, request-coalescing, in-memory-cache, high-throughput, io-optimization
