#create_queue(options = {}) ⇒ Queue

Examples:

Request syntax with placeholder values


queue = sqs.create_queue({
  queue_name: "String", # required
  attributes: {
    "All" => "String",
  },
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :queue_name (required, 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.

  • :attributes (Hash<String,String>)

    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).

    • ‘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 a ` ReceiveMessage ` action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.

    • ‘RedrivePolicy` - 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][2

      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.

      <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>
      
    • ‘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][3

      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 always `alias/aws/sqs`, the alias of a custom CMK can, for example, be `alias/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). 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?].

    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 the ‘MessageGroupId` for 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][11

      in the *Amazon Simple Queue Service

      Developer Guide*.

      • 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.
