*
* The AttributeNames
parameter is optional, but if you don't specify values for this parameter, the

*
*
*
* In the future, new attributes might be added. If you write code that calls this action, we recommend that you
* structure your code so that it can handle new attributes gracefully.
*
*
*
* The following attributes are supported:
*
*
*
* The ApproximateNumberOfMessagesDelayed
, ApproximateNumberOfMessagesNotVisible
, and
* ApproximateNumberOfMessages
metrics may not achieve consistency until at least 1 minute after the
* producers stop sending messages. This period is required for the queue metadata to reach eventual consistency.
*
*
*
* -
*
* All
– Returns all values.
*
*
* -
*
* ApproximateNumberOfMessages
– Returns the approximate number of messages available for retrieval
* from the queue.
*
*
* -
*
* ApproximateNumberOfMessagesDelayed
– 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.
*
*
* -
*
* 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
* deleted or have not yet reached the end of their visibility window.
*
*
* -
*
* CreatedTimestamp
– Returns the time when the queue was created in seconds (epoch time).
*
*
* -
*
* DelaySeconds
– Returns the default delay on the queue in seconds.
*
*
* -
*
* LastModifiedTimestamp
– Returns the time when the queue was last changed in seconds (epoch time).
*
*
* -
*
* MaximumMessageSize
– Returns the limit of how many bytes a message can contain before Amazon SQS
* rejects it.
*
*
* -
*
* MessageRetentionPeriod
– 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 MessageRetentionPeriod
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 MessageRetentionPeriod
is reduced below the age of existing messages.
*
*
* -
*
* Policy
– Returns the policy of the queue.
*
*
* -
*
* QueueArn
– Returns the Amazon resource name (ARN) of the queue.
*
*
* -
*
* ReceiveMessageWaitTimeSeconds
– Returns the length of time, in seconds, for which the
* ReceiveMessage
action waits for a message to arrive.
*
*
* -
*
* 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 dead-letter queues:
*
*
* -
*
* RedrivePolicy
– The string that includes the parameters for the dead-letter queue functionality of
* the source queue as a JSON object. The parameters are as follows:
*
*
* -
*
* 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. Default: 10. When the ReceiveCount
for a message exceeds the
* maxReceiveCount
for a queue, Amazon SQS moves the message to the dead-letter-queue.
*
*
*
*
* -
*
* RedriveAllowPolicy
– 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:
*
*
* -
*
* redrivePermission
– The permission type that defines which source queues can specify the current
* queue as the dead-letter queue. Valid values are:
*
*
* -
*
* allowAll
– (Default) Any source queues in this Amazon Web Services account in the same Region can
* specify this queue as the dead-letter queue.
*
*
* -
*
* denyAll
– No source queues can specify this queue as the dead-letter queue.
*
*
* -
*
* byQueue
– Only queues specified by the sourceQueueArns

*
*
*
*
* -

* as the dead-letter queue and redrive messages. You can specify this parameter only when the
* redrivePermission
parameter is set to byQueue
. You can specify up to 10 source queue
* ARNs. To allow more than 10 source queues to specify dead-letter queues, set the redrivePermission
* parameter to allowAll
.
*
*
*
*
*
*
*
* The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard
* queue must also be a standard queue.
*
*
*
* The following attributes apply only to server-side-encryption:
*
*
* -
*
* KmsMasterKeyId
– Returns the ID of an Amazon Web Services managed customer master key (CMK) for
* Amazon SQS or a custom CMK. For more information, see Key Terms.
*
*
* -
*
* KmsDataKeyReusePeriodSeconds
– Returns the length of time, in seconds, for which Amazon SQS can
* reuse a data key to encrypt or decrypt messages before calling KMS again. For more information, see How Does the Data Key Reuse Period Work?.
*
*
* -
*
* SqsManagedSseEnabled
– Returns information about whether the queue is using SSE-SQS encryption using
* SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS).
*
*
*
*
* 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
* or per message group. Valid values are perQueue
and perMessageGroupId
. The
* perMessageGroupId
value is allowed only when the value for DeduplicationScope
is
* messageGroup
.
*
*
*
*
* To enable high throughput for FIFO queues, do the following:
*
*
* -
*
* Set DeduplicationScope
to messageGroup
.
*
*
* -
*
* Set FifoThroughputLimit
to perMessageGroupId
.
*
*
*
*
* If you set these attributes to anything other than the values shown for enabling high throughput, normal
* throughput is in effect and deduplication occurs as specified.

* queue or when a message has been sent with a delay parameter.
*
*
* -
*

* flight. Messages are considered to be in flight if they have been sent to a client but have not yet been

*
*
*
*
* -
*
* RedriveAllowPolicy
– 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:

* specify this queue as the dead-letter queue.

* ARNs. To allow more than 10 source queues to specify dead-letter queues, set the redrivePermission
* parameter to allowAll
.

*
*
* -
*
* DeduplicationScope
– Specifies whether message deduplication occurs at the message group or queue
* level. Valid values are messageGroup
and queue
