A job queue processes time-consuming tasks in the background, keeping web requests fast while handling emails, notifications, and data processing asynchronously.
Why It Matters
Queues prevent slow operations from blocking user requests, enabling features like email sending and data processing without slowing down the user experience.
When to Use This
- Sending welcome emails after user registration
- Generating reports and exports in background
- Processing image uploads and resizing
- Scheduled tasks running at specific times
Examples
- User uploads video, queue processes it to multiple resolutions
- Order placed, queue handles payment, inventory, and shipping updates
- Scheduled daily report generation at 3 AM
