SQS visibility timeout semantics
In Amazon SQS, what happens if a consumer does not delete a message before its visibility timeout expires?
Options
- 1The message is permanently deleted from the queue, since the broker discards it on timeout
- 2The message becomes visible again and may be delivered to another consumer
- 3The queue is paused automatically, so no other consumer receives a message until one acks it
- 4The message moves to the dead-letter queue, since one failed window marks it poison
