Network.AWS.SQS.CreateQueue
Description
Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following caveats in mind:
- If you don't specify the
FifoQueueattribute, Amazon SQS creates a standard queue. - If you don't provide a value for an attribute, the queue is created with the default value for the attribute.
- If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.
To successfully create a new queue, you must provide a queue name that adheres to the limits related to queues and is unique within the scope of your queues.
To get the queue URL, use the GetQueueUrl GetQueueUrl QueueName parameter. be aware of existing queue names:
- If you provide the name of an existing queue along with the exact names and values of all the queue's attributes,
CreateQueuereturns the queue URL for the existing queue. - If the queue name, attribute names, or attribute values don't match an existing queue,
CreateQueuereturns an error.

Creating a Request
Arguments
| :: Text | |
| -> CreateQueue |
Creates a value of CreateQueue with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
cqAttributes- A map of attributes with their corresponding values. The following lists the names, descriptions, and values of the special request parameters that theCreateQueueaction 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). The default is 0 (zero). *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). The default is 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). The default is 345,600 (4 days). *Policy- The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS IAM Policies in the Amazon IAM User Guide . *ReceiveMessageWaitTimeSeconds- The length of time, in seconds, for which aReceiveMessageRedrivePolicy- The string that includes the parameters for the 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 ofmaxReceiveCountis exceeded. *maxReceiveCount- The number of times a message is delivered to the source queue before being moved to the dead-letter queue. *VisibilityTimeout- The visibility timeout for the queue. Valid values: An integer from 0 to 43,200 (12 hours). The default is 30. 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- The ID of an AWS-managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms . While the alias of the AWS-managed CMK for Amazon SQS is alwaysaliasawssqs, the alias of a custom CMK can, for example, bealias/MyAlias. For more examples, see KeyId in the AWS 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 AWS KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). The default is 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? . The following attributes apply only to FIFO (first-in-first-out) queues : *FifoQueue- Designates a queue as FIFO. Valid values:true,false. 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 theMessageGroupIdfor your messages explicitly. For more information, see FIFO Queue Logic in the Amazon Simple Queue Service Developer Guide . *ContentBasedDeduplication- Enables content-based deduplication. Valid values:true,false. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service Developer Guide . * Every message must have a uniqueMessageDeduplicationId, * You may provide aMessageDeduplicationIdexplicitly. * If you aren't able to provide aMessageDeduplicationIdand you enableContentBasedDeduplicationfor your queue, Amazon SQS uses a SHA-256 hash to generate theMessageDeduplicationIdusing the body of the message (but not the attributes of the message). * If you don't provide aMessageDeduplicationIdand the queue doesn't haveContentBasedDeduplicationset, the action fails with an error. * If the queue hasContentBasedDeduplicationset, yourMessageDeduplicationIdoverrides the generated one. * WhenContentBasedDeduplicationis 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 withContentBasedDeduplicationenabled and then another message with aMessageDeduplicationIdthat is the same as the one generated for the firstMessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered. Any other valid special request parameters (such as the following) are ignored: *ApproximateNumberOfMessages*ApproximateNumberOfMessagesDelayed*ApproximateNumberOfMessagesNotVisible*CreatedTimestamp*LastModifiedTimestamp*QueueArncqQueueName- 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.fifosuffix. Queue names are case-sensitive.
