Multi Step Processes medium
A worker pulls a message from a queue with a 'Visibility Timeout' of 30 seconds. The processing task actually takes 45 seconds. What likely happens?
- A The worker crashes.
- B The queue deletes the message automatically.
- C The message becomes visible again in the queue after 30s, causing a second worker to pick it up (Duplicate Processing).
- D The queue waits for the worker to finish.
Answer: C. The message becomes visible again in the queue after 30s, causing a second worker to pick it up (Duplicate Processing).
The timeout is the queue saying, 'I'll hide this for 30s.' If you don't delete it by then, the queue assumes the worker died and redelivers the message.
One system design question a day, with spaced repetition so the ones you miss come back.
