A map of attributes with their corresponding values.

The following lists the names, descriptions, and values of the special request parameters that the ‘CreateQueue` action uses:

‘DelaySeconds` – 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 seconds (15 minutes). Default: 0.
‘MaximumMessageSize` – 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) to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).
‘MessageRetentionPeriod` – The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days). 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` – The queue’s policy. A valid Amazon Web Services policy. For more information about policy structure, see [Overview of Amazon Web Services IAM Policies] in the *IAM User Guide*.
‘ReceiveMessageWaitTimeSeconds` – The length of time, in seconds, for which a ` ReceiveMessage ` action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.
‘VisibilityTimeout` – 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 [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` parameter can specify this queue as the dead-letter queue.
- ‘sourceQueueArns` – 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 `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`.

<note markdown=“1”> 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.

</note>

The following attributes apply only to [server-side-encryption]:

‘KmsMasterKeyId` – 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]. While the alias of the Amazon Web Services managed CMK for Amazon SQS is always `alias/aws/sqs`, the alias of a custom CMK can, for example, be `alias/MyAlias `. For more examples, see [KeyId] in the *Key Management Service API Reference*.
‘KmsDataKeyReusePeriodSeconds` – The length of time, in seconds, for which Amazon SQS can reuse a [data key] 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. For more information, see [How Does the Data Key Reuse Period Work?]
‘SqsManagedSseEnabled` – Enables server-side queue 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` – Designates a queue as FIFO. Valid values are `true` and `false`. If you don’t specify the ‘FifoQueue` attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can’t change it for an existing queue. When you set this attribute, you must also provide the ‘MessageGroupId` for your messages explicitly.

For more information, see [FIFO queue logic] in the *Amazon SQS Developer Guide*.
‘ContentBasedDeduplication` – Enables content-based deduplication. Valid values are `true` and `false`. For more information, see

Exactly-once processing][13

in the *Amazon SQS Developer Guide*.

Note the following:
- Every message must have a unique ‘MessageDeduplicationId`.
  - You may provide a ‘MessageDeduplicationId` explicitly.
  - If you aren’t able to provide a ‘MessageDeduplicationId` and you enable `ContentBasedDeduplication` for your queue, Amazon SQS uses a SHA-256 hash to generate the `MessageDeduplicationId` using the body of the message (but not the attributes of the message).
  - If you don’t provide a ‘MessageDeduplicationId` and the queue doesn’t have ‘ContentBasedDeduplication` set, the action fails with an error.
  - If the queue has ‘ContentBasedDeduplication` set, your `MessageDeduplicationId` overrides the generated one.
- When ‘ContentBasedDeduplication` 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.
- If you send one message with ‘ContentBasedDeduplication` enabled and then another message with a `MessageDeduplicationId` that is the same as the one generated for the first `MessageDeduplicationId`, the two messages are treated as duplicates and only one copy of the message is delivered.

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.

For information on throughput quotas, see [Quotas related to messages] in the *Amazon SQS Developer Guide*.

# File 'lib/aws-sdk-sqs/types.rb', line 521

class CreateQueueRequest < Struct.new(
  :queue_name,
  :attributes,
  :tags)
  SENSITIVE = []
  include Aws::Structure
end

#queue_name ⇒ `String`

The name of the new queue. The following limits apply to this name:

A queue name can have up to 80 characters.
Valid values: alphanumeric characters, hyphens (‘-`), and underscores (`_`).
A FIFO queue name must end with the ‘.fifo` suffix.

Queue URLs and names are case-sensitive.

Returns:

end

#tags ⇒ `Hash<String,String>`

Add cost allocation tags to the specified Amazon SQS queue. For an overview, see [Tagging Your Amazon SQS Queues] in the *Amazon SQS Developer Guide*.

When you use queue tags, keep the following guidelines in mind:

Adding more than 50 tags to a queue isn’t recommended.
Tags don’t have any semantic meaning. Amazon SQS interprets tags as character strings.
Tags are case-sensitive.
A new tag with a key identical to that of an existing tag overwrites the existing tag.

For a full list of tag restrictions, see [Quotas related to queues] in the *Amazon SQS Developer Guide*.

<note markdown=“1”> To be able to tag a queue on creation, you must have the ‘sqs:CreateQueue` and `sqs:TagQueue` permissions.

Cross-account permissions don't apply to this action. For more

information, see [Grant cross-account permissions to a role and a username] in the *Amazon SQS Developer Guide*.
