# Caching

**Canonical:** https://apis.io/providers/caching/

**APIs profiled:** 0

An index and topic collection covering API-accessible caching services, in-memory data stores, key-value caches, and edge/CDN cache APIs. Caching reduces latency, lowers backend load, and improves API consumer experience by serving frequently requested data from memory or geographically distributed edges. This collection covers managed in-memory data stores like Redis, Amazon ElastiCache, and Google Cloud Memorystore; high-throughput alternatives such as Dragonfly, Aerospike, and Hazelcast; and edge cache services from Cloudflare, Fastly, Akamai, AWS CloudFront, and Vercel. It focuses on caching as a service or product, not on HTTP cache header semantics handled at the gateway or proxy layer.

## Use cases (8)

- **Session and Token Caching** — Applications cache authenticated sessions, JWTs, and OAuth tokens in Redis or Memcached so API gateways can validate requests without round-tripping to an identity provider on e...
- **API Response Caching** — API gateways and edge networks cache GET responses keyed by URL and headers so repeated requests for the same resource are served from cache, reducing backend cost and latency.
- **Database Query Result Caching** — Backend services cache expensive database query results in Redis or Hazelcast with TTLs so subsequent identical queries return immediately without hitting the source database.
- **Rate Limiting and Counters** — Redis and similar in-memory stores back distributed rate limiters, leaderboards, and counters using atomic increment operations that scale to millions of operations per second.
- **CDN Static Asset Delivery** — Cloudflare, Fastly, CloudFront, and Akamai cache images, JavaScript, CSS, and other static assets at edge POPs to minimize origin bandwidth and serve global users with low latency.
- **Edge Personalization and Feature Flags** — Edge KV stores like Vercel Edge Config and Cloudflare Workers KV hold feature flags, A/B test configurations, and personalization data accessed by edge functions on every request.
- **Real-Time Leaderboards and Pub/Sub** — Redis sorted sets and pub/sub channels power real-time leaderboards, chat backends, and notification fanout patterns where in-memory speed is required.
- **Pre-Warming and Cache Stampede Prevention** — Applications pre-populate caches before traffic spikes and use techniques like singleflight and probabilistic early expiration backed by Redis to prevent thundering herds agains...
