Queues & Asynchronous Tasks

At the edge, users expect lightning-fast responses. But not every task needs to happen instantly. Sometimes, you have operations that can run in the background, like sending emails, processing analytics, or generating reports.

These are called asynchronous tasks. They don't block the user's immediate request, allowing your Worker to respond quickly while the longer task completes separately.

Cloudflare Queues provide a robust way to manage these asynchronous tasks. They act as a buffer, allowing different parts of your application (often Cloudflare Workers) to communicate without needing to be directly available at the same time.

Think of it like a to-do list where one Worker adds tasks, and another Worker picks them up when it's ready.
