Durable Objects: Easy, Fast, Correct — Choose three

What this post added

This post introduces Durable Objects as a significant enhancement to Cloudflare Workers. It explains how Durable Objects provide a single-threaded execution model with private, persistent storage, which simplifies state management and eliminates common race conditions and performance issues previously encountered when interacting with distributed storage. The post highlights that these improvements are achieved by fixing the runtime model, making applications correct by default without requiring code changes, and significantly improving performance by reducing I/O round trips and enabling in-memory caching.
