**To set queue attributes**

This example sets the specified queue to a delivery delay of 10 seconds, a maximum message size of 128 KB (128 KB * 1,024 bytes), a message retention period of 3 days (3 days * 24 hours * 60 minutes * 60 seconds), a receive message wait time of 20 seconds, and a default visibility timeout of 60 seconds. This example also associates the specified dead letter queue with a maximum receive count of 1,000 messages.
