*
*
*
* -
*

* -
*
* ApproximateNumberOfMessages – Returns the approximate number of messages available for retrieval
* from the queue.
*
*

* queue or when a message has been sent with a delay parameter.
*
*
* -
*
* ApproximateNumberOfMessagesNotVisible – Returns the approximate number of messages that are in
* flight. Messages are considered to be in flight if they have been sent to a client but have not yet been

*
*
* -
*
* deadLetterTargetArn – The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS
* moves messages after the value of maxReceiveCount is exceeded.
*
*
* -
*
* maxReceiveCount – The number of times a message is delivered to the source queue before being moved
* to the dead-letter queue. When the ReceiveCount for a message exceeds the
* maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.
*
*
*
*
* -
*
* VisibilityTimeout – Returns the visibility timeout for the queue. For more information about the
* visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide.
*
*
*
*
* The following attributes apply only to server-side-encryption:

*
*
*
*
* The following attributes apply only to FIFO
* (first-in-first-out) queues:
*
*
* -
*
* FifoQueue – Returns information about whether the queue is FIFO. For more information, see FIFO queue logic in the Amazon SQS Developer Guide.
*
*
*
* To determine whether a queue is FIFO, you
* can check whether QueueName ends with the .fifo suffix.
*
*
* -
*
* ContentBasedDeduplication – Returns whether content-based deduplication is enabled for the queue.
* For more information, see Exactly-once processing in the Amazon SQS Developer Guide.
*
*
*
*
* The following attributes apply only to high
* throughput for FIFO queues:
*
*
* -
*
* DeduplicationScope – Specifies whether message deduplication occurs at the message group or queue
* level. Valid values are messageGroup and queue.
*
*
* -
*
* FifoThroughputLimit – Specifies whether the FIFO queue throughput quota applies to the entire queue

* -
*
