This period is required for the queue metadata to reach eventual consistency.</p> </important> <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. When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the <code>MessageRetentionPeriod</code> attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the <code>MessageRetentionPeriod</code> is reduced below the age of existing messages.</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>VisibilityTimeout</code> – Returns the visibility timeout for the queue. For more information about the visibility timeout, see <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-visibility-timeout.html">Visibility Timeout</a> in the <i>Amazon SQS Developer Guide</i>.</p></li> </ul> <p>The following attributes apply only to <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html">dead-letter queues:</a></p> <ul>  <li>   <p><code>RedrivePolicy</code> – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object.

Default: 10. 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>RedriveAllowPolicy</code> – The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:</p>   <ul>    <li>     <p><code>redrivePermission</code> – The permission type that defines which source queues can specify the current queue as the dead-letter queue. Valid values are:</p>     <ul>      <li>       <p><code>allowAll</code> – (Default) Any source queues in this Amazon Web Services account in the same Region can specify this queue as the dead-letter queue.</p></li>      <li>       <p><code>denyAll</code> – No source queues can specify this queue as the dead-letter queue.</p></li>      <li>       <p><code>byQueue</code> – Only queues specified by the <code>sourceQueueArns</code> parameter can specify this queue as the dead-letter queue.</p></li>     </ul></li>    <li>     <p><code>sourceQueueArns</code> – The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the <code>redrivePermission</code> parameter is set to <code>byQueue</code>. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the <code>redrivePermission</code> parameter to <code>allowAll</code>.</p></li>   </ul></li> </ul><note>  <p>The dead-letter queue of a FIFO queue must also be a FIFO queue.
