If you write code that calls this action, we recommend that you structure your code so that it can handle new attributes gracefully.</p> </note> <p>The following attributes are supported:</p> <ul> <li> <p> <code>All</code> - Returns all values. </p> </li> <li> <p> <code>ApproximateNumberOfMessages</code> - Returns the approximate number of messages available for retrieval from the queue.</p> </li> <li> <p> <code>ApproximateNumberOfMessagesDelayed</code> - Returns the approximate number of messages in the queue that are delayed and not available for reading immediately. This can happen when the queue is configured as a delay queue or when a message has been sent with a delay parameter.</p> </li> <li> <p> <code>ApproximateNumberOfMessagesNotVisible</code> - Returns the approximate number of messages that are in flight. Messages are considered to be <i>in flight</i> if they have been sent to a client but have not yet been deleted or have not yet reached the end of their visibility window. </p> </li> <li> <p> <code>CreatedTimestamp</code> - Returns the time when the queue was created in seconds (<a href="http://en.wikipedia.org/wiki/Unix_time">epoch time</a>).</p> </li> <li> <p> <code>DelaySeconds</code> - Returns the default delay on the queue in seconds.</p> </li> <li> <p> <code>LastModifiedTimestamp</code> - Returns the time when the queue was last changed in seconds (<a href="http://en.wikipedia.org/wiki/Unix_time">epoch time</a>).</p> </li> <li> <p> <code>MaximumMessageSize</code> - Returns the limit of how many bytes a message can contain before Amazon SQS rejects it.</p> </li> <li> <p> <code>MessageRetentionPeriod</code> - Returns the length of time, in seconds, for which Amazon SQS retains a message.</p> </li> <li> <p> <code>Policy</code> - Returns the policy of the queue.</p> </li> <li> <p> <code>QueueArn</code> - Returns the Amazon resource name (ARN) of the queue.</p> </li> <li> <p> <code>ReceiveMessageWaitTimeSeconds</code> - Returns the length of time, in seconds, for which the <code>ReceiveMessage</code> action waits for a message to arrive. </p> </li> <li> <p> <code>RedrivePolicy</code> - Returns the string that includes the parameters for dead-letter queue functionality of the source queue. For more information about the redrive policy and dead-letter queues, see <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html">Using Amazon SQS Dead-Letter Queues</a> in the <i>Amazon Simple Queue Service Developer Guide</i>. </p> <ul> <li> <p> <code>deadLetterTargetArn</code> - The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of <code>maxReceiveCount</code> is exceeded.</p> </li> <li> <p> <code>maxReceiveCount</code> - The number of times a message is delivered to the source queue before being moved to the dead-letter queue. When the <code>ReceiveCount</code> for a message exceeds the <code>maxReceiveCount</code> for a queue, Amazon SQS moves the message to the dead-letter-queue.</p> </li> </ul> </li> <li> <p> <code>VisibilityTimeout</code> - Returns the visibility timeout for the queue.
