DURABLE OBJECTS ARE MADE FOR AGENTS

Summary from the TLDR newsletter

Cloudflare Durable Objects are a primitive that combines a serverless V8 isolate for running code, a paired SQLite instance, and request routing to a particular isolate. They allow developers to start thinking about their service as a set of many event-driven objects rather than as a bunch of services talking to a database. Durable Objects run explicitly in a single-threaded manner and come with native support for WebSockets. They are cheap and extremely token-efficient.
