Your Worker can now have its own cache in front of it
Curated from Cloudflare Blog
For practitioners managing high-traffic edge applications, the latency cost of invoking a Worker for every single request is a persistent operational burden. While Workers offer incredible flexibility, they introduce execution overhead that can become significant under heavy load or when handling simple, static assets. This new capability fundamentally shifts the architecture by placing a regionally tiered cache directly in front of the Worker entrypoint. This means you can offload repetitive, read-heavy requests without modifying your core logic, relying instead on standard HTTP headers for configuration. It effectively decouples cache management from application code, allowing for infinitely composable strategies that respect existing caching semantics. You no longer need to bake complex caching logic into your script or manage separate edge nodes. The immediate benefit is reduced cold starts and lower compute costs, but the deeper value lies in the simplicity of managing cache behavior through standard protocols rather than custom code. Adopt this pattern for high-volume, low-variability endpoints to maximize efficiency.
We are launching Workers Cache, a regionally tiered cache that sits directly in front of your Worker entrypoints.
