Option 2: Queue Delay
Option 3: Retry Threshold
Option 4: Queue Visibility Timeout

Answer 1

The configuration value that controls how long something has to process and delete a queue message before it reappears is the Queue Visibility Timeout.

Step-by-step explanation:

The configuration value that controls how long something has to process and delete a queue message before it reappears is the Queue Visibility Timeout. Queue visibility timeout is a setting in message queuing systems that determines how long a message will remain in the queue before becoming visible to consumer applications again.

For example, in Amazon Simple Queue Service (Amazon SQS), the default visibility timeout is 30 seconds. If a consumer application receives a message from the queue but fails to process and delete it within 30 seconds, the message becomes visible in the queue again for other consumers to process.

This is an important setting to ensure message processing reliability and prevent message loss or duplication.
