What this card says
What it is
After visibility timeout the message reappears. After maxReceiveCount it can go to a dead-letter queue (DLQ).
Why it matters
DLQ protects the main queue from poison messages and keeps a copy for debugging.
How / example
Attach redrive policy maxReceiveCount=3 to an SQS DLQ on yourname-orders.
