Gets attributes for the specified queue.
sqs_get_queue_attributes(QueueUrl, AttributeNames)[required] The URL of the Amazon SQS queue whose attribute information is retrieved.
Queue URLs and names are case-sensitive.
A list of attributes for which to retrieve information.
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:
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.
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.
RedrivePolicy - 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
Using Amazon SQS Dead-Letter Queues
in the Amazon Simple Queue Service Developer Guide.
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 Simple Queue Service Developer Guide.
The following attributes apply only to server-side-encryption:
KmsMasterKeyId - Returns the ID of an AWS-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 AWS KMS again. For more information,
see How Does the Data Key Reuse Period Work?.
The following attributes apply only to FIFO (first-in-first-out) queues:
FifoQueue - Returns whether the queue is FIFO. For more
information, see FIFO Queue Logic
in the Amazon Simple Queue Service 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 Simple Queue Service Developer Guide.

Some actions take lists of parameters. These lists are specified using
the param.n notation. Values of n are integers starting from 1. For
example, a parameter list with two elements looks like this:
&Attribute.1=first
&Attribute.2=second
