LLM_BEHAVIOR
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
BullMQ requires maxRetriesPerRequest null for proper reconnection handling
Message: BullMQ queue/worker created without maxRetriesPerRequest: null on Redis connection. This will cause workers to stop on Redis connection issues.
No stalled job event handler
Severity: WARNING
Workers should handle stalled events to detect crashed workers
Message: Worker created without 'stalled' event handler. Stalled jobs indicate worker crashes and should be monitored.
No failed job event handler
Severity: WARNING
Workers should handle failed events for monitoring and alerting
Message: Worker created without 'failed' event handler. Failed jobs should be logged and monitored.
No graceful shutdown handling
Severity: WARNING
Workers should gracefully shut down on SIGTERM/SIGINT
Message: Worker file without graceful shutdown handling. Jobs may be orphaned on deployment.
Awaiting queue.add in request handler
Severity: INFO
Queue additions should be fire-and-forget in request handlers
Message: Queue.add awaited in request handler. Consider fire-and-forget for faster response.
Potentially large data in job payload
Severity: WARNING
Job data should be small - pass IDs not full objects
Message: Job appears to have large inline data. Pass IDs instead of full objects to keep Redis memory low.
Job without timeout configuration
Severity: INFO
Jobs should have timeouts to prevent infinite execution
Message: Job added without explicit timeout. Consider adding timeout to prevent stuck jobs.
Retry without backoff strategy
Severity: WARNING
Retries should use exponential backoff to avoid thundering herd
Message: Job has retry attempts but no backoff strategy. Use exponential backoff to prevent thundering herd.
Repeatable job without explicit timezone
Severity: WARNING
Repeatable jobs should specify timezone to avoid DST issues
Message: Repeatable job without explicit timezone. Will use server local time which can drift with DST.
Potentially high worker concurrency
Severity: INFO
High concurrency can overwhelm downstream services
Message: Worker concurrency is high. Ensure downstream services can handle this load (DB connections, API rate limits).
1. Email request received (API)
2. Job queued with rate limiting (bullmq-specialist)
3. Worker processes with backoff (bullmq-specialist)
4. Email sent via provider (email-systems)
5. Status tracked in Redis (redis-specialist)
Background Processing Stack
Skills: bullmq-specialist, backend, devops
Workflow:
1. API receives request (backend)
2. Long task queued for background (bullmq-specialist)
3. Worker processes async (bullmq-specialist)
4. Result stored/notified (backend)
5. Workers scaled per load (devops)
1. Repeatable jobs defined (bullmq-specialist)
2. Cron patterns with timezone (bullmq-specialist)
3. Jobs execute on schedule (bullmq-specialist)
4. State managed in Redis (redis-specialist)
5. Results handled (backend)
