BullMQ Specialist

BullMQ expert for Redis-backed job queues, background processing, and reliable async execution in Node.js/TypeScript applications.

Principles

• Jobs are fire-and-forget from the producer side - let the queue handle delivery
• Always set explicit job options - defaults rarely match your use case
• Idempotency is your responsibility - jobs may run more than once
• Backoff strategies prevent thundering herds - exponential beats linear
• Dead letter queues are not optional - failed jobs need a home
• Concurrency limits protect downstream services - start conservative
• Job data should be small - pass IDs, not payloads
• Graceful shutdown prevents orphaned jobs - handle SIGTERM properly
