Cloudflare KV: a key-value store for your Workers
Cloudflare Workers KV is an edge key-value store that lets you store and retrieve data globally with very low read latency. The guide covers creating a KV namespace, binding it to a Worker via wrangler.jsonc, and using the put/get/delete/list API. It also covers storing JSON objects, setting TTL-based key expiration for sessions and caches, and listing keys by prefix. A key caveat: KV is optimized for read-heavy workloads — writes propagate across regions within a few seconds, making it unsuitable for data requiring immediate consistency (e.g., financial records). For those cases, Cloudflare D1 or Durable Objects are recommended.
