Background Job Worker

Overview

A Background Job Worker processes asynchronous tasks like email sending or data imports off the main request thread, using queues like Bull or Sidekiq for reliability.

It ensures non-blocking UIs and fault-tolerant execution.

When to use

Implement Background Jobs when:

Handling long-running tasks in web apps.
Processing after user actions (e.g., uploads).
Scaling compute-intensive operations.
Needing retries and dead-letter queues.

Notes

Note: Use unique job IDs for idempotency.

Monitor queue lengths for bottlenecks.

Test with fake queues in dev.
