Hyperdrive is a service that enables developers to build performant global apps on Cloudflare Workers with their existing SQL databases. It reduces latency by caching query results and minimizing network round trips, allowing for faster and more secure connections between the Worker and the origin database. Hyperdrive uses Cloudflare's cache and architecture to achieve this, with a single global Endpoint for each Hyperdrive located near its origin database. This approach allows for significant reductions in latency and bandwidth usage, making it an attractive solution for developers building on Workers. The service is now available on the free plan of Cloudflare Workers, allowing developers to get started with a single Wrangler command or using the dashboard.
