What Is UUID Job ID?

When you enqueue work, return a UUID job ID; clients poll /jobs/{id} for status and can cancel by id.
Because it is random, ids from different workers never collide.

How to generate

Enqueue and return a v4 UUID.
Store job state keyed by that id.
Expose status/cancel endpoints using the id.

Use Cases

Video transcoding.
Report generation.
Email digests.

Code Examples

JavaScript

const id = crypto.randomUUID();

Python

import uuid
id = uuid.uuid4()

Frequently Asked Questions

Job ID in the URL?

Yes — it is opaque and unguessable; scope it to the owning user to prevent cross-access.

How long keep job records?

Until terminal (success/fail) plus a short retention for status polling, then delete.
