Developers should avoid using Celery for tasks that require sub-second latency because Celery's broker overhead makes it unsuitable for real-time processing where async request handling is more suitable. Avoid storing large payloads in Celery task arguments; instead, pass database IDs and retrieve the data within the task. Do not run Celery workers without monitoring, as unhandled task failures fail silently without alerting unless Flower or Sentry integration is configured.
