CreateQueue

Description

The CreateQueue action creates a new queue.

When you request CreateQueue, you provide a name for the queue. To successfully create a new queue, you must provide a name that is unique within the scope of your own queues. If you provide the name of an existing queue, a new queue isn't created and an error isn't returned. Instead, the request succeeds and the queue URL for the existing queue is returned (for more information about queue URLs, see Queue and Message Identifiers in the Amazon SQS Developer Guide). Exception: if you provide a value for DefaultVisibilityTimeout that is different from the value for the existing queue, you receive an error.

	Note
	If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

A default value for the queue's visibility timeout (30 seconds) is set when the queue is created. You can override this value with the DefaultVisibilityTimeout request parameter. For more information, see Visibility Timeout in the Amazon SQS Developer Guide.
