What can happen in this scenario?
AWS SQS sends notification after 15 days for inactivity on queue
AWS SQS can delete queue after 30 days without notification
AWS SQS marks queue inactive after 30 days
AWS SQS notifies the user after 2 weeks and deletes the queue after 3 weeks.
Explanations:
AWS SQS does not send notifications specifically after 15 days of inactivity on a queue. There is no default notification period for inactivity.
AWS SQS can delete a queue automatically after 30 days of inactivity without notifying the user. This is the default behavior for inactive queues.
AWS SQS does not mark queues as inactive after 30 days. The queue is only eligible for deletion after 30 days of inactivity.
AWS SQS does not notify users after 2 weeks nor delete the queue after 3 weeks. It can delete the queue after 30 days of inactivity, with no notification.
I plot that the answer is:
AWS SQS can delete queue after 30 days without notification
