Original: Running Celery in Production: What We Do Differently After Years of Real Projects
Short summary
A practical guide to running Celery in production based on years of real-world deployments. Covers critical configurations like late task acknowledgement, worker memory and task limits, Flower monitoring setup, and retry patterns with exponential backoff. The core lesson: Celery fails silently, so proactive monitoring and correct acknowledgement settings are essential to prevent silent task loss and queue buildup.
- •Enable task_acks_late and task_reject_on_worker_lost to prevent silent task loss
- •Use Flower for real-time monitoring with alerts on queue depth and worker count
- •Implement retry with exponential backoff and distinguish retryable from non-retryable failures
