Steps

  1. Set acks_late=True + task_reject_on_worker_lost=True for at-least-once semantics
  2. Make every task idempotent (natural keys, upserts) because retries WILL duplicate
  3. Set explicit time limits (soft + hard) and autoretry_for with backoff + jitter
  4. Route long tasks to dedicated queues; keep result backend off unless you read results
