    • Maximum Message Length: the maximum length of the message that is sent to the queue.

    • Long Polling Period: the maximum duration for which long polling requests are held after the ReceiveMessage operation is called. If you set this parameter to 0, the long polling mode is disabled.

    • Visibility Timeout Period: the duration for which a message stays in the Inactive state after the message is received from the queue. For more information, see Message visibility.

    • Message Retention Period: the maximum duration for which a message is retained in the queue. After the specified retention period ends, the message is deleted regardless of whether the message is received.
