Transcript

  1. 00:00This is a local simulation: twenty arrivals per second and two workers.
  2. 00:06After ten seconds, backlog reaches 180 messages.
  3. 00:12To recover, set arrivals to zero and increase to fifty workers.
  4. 00:18Advance ten seconds: the queue drains and work completes.
  5. 00:24With permanent failures, three attempts move a message to the DLQ.

Queue, retries and recovery

Adjust arrivals, workers and failures to observe backlog and dead letters. An educational model inspired by the cases, with no production data.
