About Cloudflare KV

Cloudflare Workers KV is a globally distributed, eventually consistent key-value data store designed for high-read volumes and low-latency access. It allows developers to store and retrieve data across Cloudflare's global network, making it ideal for building dynamic APIs and websites that require fast data access from anywhere in the world. This product is particularly useful for scenarios like caching API responses, storing user configurations and preferences, or managing user authentication details. Its architecture is optimized for frequently read keys, which benefit from an internal cache, leading to typical latencies between 500µs and 10ms for "hot" keys. Developers can interact with Workers KV using Workers Bindings for direct integration with Cloudflare Workers or via a REST API for external applications, with SDKs available for TypeScript, Python, and Go. Cloudflare Workers KV is part of a suite of Cloudflare storage options, complementing services like R2 for large object storage, Durable Objects for consistent stateful serverless workloads, and D1 for lightweight SQL databases. It's specifically recommended for session data, credentials, and configuration data that are read at high rates and do not require immediate consistency.
