The name of the queue

<p>A map of attributes to set.</p> <p>The following lists the names, descriptions, and values of the special request parameters that the <code>SetQueueAttributes</code> action uses:</p> <ul> <li> <p> <code>DelaySeconds</code> – The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 (15 minutes). Default: 0. </p> </li> <li> <p> <code>MaximumMessageSize</code> – The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) up to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB). </p> </li> <li> <p> <code>MessageRetentionPeriod</code> – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer representing seconds, from 60 (1 minute) to 1,209,600 (14 days). Default: 345,600 (4 days). </p> </li> <li> <p> <code>Policy</code> – The queue's policy. A valid Amazon Web Services policy. For more information about policy structure, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/PoliciesOverview.html">Overview of Amazon Web Services IAM Policies</a> in the <i>Identity and Access Management User Guide</i>. </p> </li> <li> <p> <code>ReceiveMessageWaitTimeSeconds</code> – The length of time, in seconds, for which a <code> <a>ReceiveMessage</a> </code> action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0. </p> </li> <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. 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 SQS 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> <note> <p>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.</p> </note> </li> <li> <p> <code>VisibilityTimeout</code> – The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. 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-server-side-encryption.html">server-side-encryption</a>:</p> <ul> <li> <p> <code>KmsMasterKeyId</code> – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-server-side-encryption.html#sqs-sse-key-terms">Key Terms</a>. While the alias of the AWS-managed CMK for Amazon SQS is always <code>alias/aws/sqs</code>, the alias of a custom CMK can, for example, be <code>alias/<i>MyAlias</i> </code>. For more examples, see <a href="https://docs.aws.amazon.com/kms/latest/APIReference/API_DescribeKey.html#API_DescribeKey_RequestParameters">KeyId</a> in the <i>Key Management Service API Reference</i>. </p> </li> <li> <p> <code>KmsDataKeyReusePeriodSeconds</code> – The length of time, in seconds, for which Amazon SQS can reuse a <a href="https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#data-keys">data key</a> to encrypt or decrypt messages before calling KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier.

Only one server-side encryption option is supported per queue (e.g. <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-sse-existing-queue.html">SSE-KMS</a> or <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-sqs-sse-queue.html">SSE-SQS</a>).</p> </li> </ul> <p>The following attribute applies only to <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html">FIFO (first-in-first-out) queues</a>:</p> <ul> <li> <p> <code>ContentBasedDeduplication</code> – Enables content-based deduplication. For more information, see <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues-exactly-once-processing.html">Exactly-once processing</a> in the <i>Amazon SQS Developer Guide</i>. Note the following: </p> <ul> <li> <p>Every message must have a unique <code>MessageDeduplicationId</code>.</p> <ul> <li> <p>You may provide a <code>MessageDeduplicationId</code> explicitly.</p> </li> <li> <p>If you aren't able to provide a <code>MessageDeduplicationId</code> and you enable <code>ContentBasedDeduplication</code> for your queue, Amazon SQS uses a SHA-256 hash to generate the <code>MessageDeduplicationId</code> using the body of the message (but not the attributes of the message). </p> </li> <li> <p>If you don't provide a <code>MessageDeduplicationId</code> and the queue doesn't have <code>ContentBasedDeduplication</code> set, the action fails with an error.</p> </li> <li> <p>If the queue has <code>ContentBasedDeduplication</code> set, your <code>MessageDeduplicationId</code> overrides the generated one.</p> </li> </ul> </li> <li> <p>When <code>ContentBasedDeduplication</code> is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.</p> </li> <li> <p>If you send one message with <code>ContentBasedDeduplication</code> enabled and then another message with a <code>MessageDeduplicationId</code> that is the same as the one generated for the first <code>MessageDeduplicationId</code>, the two messages are treated as duplicates and only one copy of the message is delivered. </p> </li> </ul> </li> </ul> <p>The following attributes apply only to <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/high-throughput-fifo.html">high throughput for FIFO queues</a>:</p> <ul> <li> <p> <code>DeduplicationScope</code> – Specifies whether message deduplication occurs at the message group or queue level. Valid values are <code>messageGroup</code> and <code>queue</code>.</p> </li> <li> <p> <code>FifoThroughputLimit</code> – Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are <code>perQueue</code> and <code>perMessageGroupId</code>. The <code>perMessageGroupId</code> value is allowed only when the value for <code>DeduplicationScope</code> is <code>messageGroup</code>.</p> </li> </ul> <p>To enable high throughput for FIFO queues, do the following:</p> <ul> <li> <p>Set <code>DeduplicationScope</code> to <code>messageGroup</code>.</p> </li> <li> <p>Set <code>FifoThroughputLimit</code> to <code>perMessageGroupId</code>.</p> </li> </ul> <p>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.</p> <p>For information on throughput quotas, see <a href="https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/quotas-messages.html">Quotas related to messages</a> in the <i>Amazon SQS Developer Guide</i>.</p>
