選択肢

1. A delivery limit on the queue together with a dead letter queue that takes the message once the limit is passed.
2. A stricter check inside the flow together with a logger that takes the message once the parsing has failed.
3. A larger prefetch on the queue together with a second subscriber that takes the message once the first has failed.
4. A longer visibility window on the queue together with a dead letter queue that takes the message once the window closes.
