    #     was first received from the queue ([epoch time][1] in milliseconds).
    #
    #   * `ApproximateReceiveCount` - Returns the number of times a message
    #     has been received from the queue but not deleted.
    #
    #   * `AWSTraceHeader` - Returns the AWS X-Ray trace header string.
    #
    #   * `SenderId`
    #
    #     * For an IAM user, returns the IAM user ID, for example
    #       `ABCDEFGHI1JKLMNOPQ23R`.
    #
    #     * For an IAM role, returns the IAM role ID, for example
    #       `ABCDE1F2GH3I4JK5LMNOP:i-a123b456`.
    #
    #   * `SentTimestamp` - Returns the time the message was sent to the queue
    #     ([epoch time][1] in milliseconds).
    #
    #   * `MessageDeduplicationId` - Returns the value provided by the
    #     producer that calls the ` SendMessage ` action.
    #
    #   * `MessageGroupId` - Returns the value provided by the producer that
    #     calls the ` SendMessage ` action. Messages with the same
    #     `MessageGroupId` are returned in sequence.
    #
    #   * `SequenceNumber` - Returns the value provided by Amazon SQS.
    #
    #
    #
    #   [1]: http://en.wikipedia.org/wiki/Unix_time
    # @option options [Array<String>] :message_attribute_names
    #   The name of the message attribute, where *N* is the index.
    #
    #   * The name can contain alphanumeric characters and the underscore
    #     (`_`), hyphen (`-`), and period (`.`).
    #
    #   * The name is case-sensitive and must be unique among all attribute
    #     names for the message.
    #
    #   * The name must not start with AWS-reserved prefixes such as `AWS.` or
    #     `Amazon.` (or any casing variants).
    #
    #   * The name must not start or end with a period (`.`), and it should
    #     not have periods in succession (`..`).
    #
    #   * The name can be up to 256 characters long.
    #
    #   When using `ReceiveMessage`, you can send a list of attribute names to
    #   receive, or you can return all of the attributes by specifying `All`
    #   or `.*` in your request. You can also use all message attributes
    #   starting with a prefix, for example `bar.*`.
    # @option options [Integer] :max_number_of_messages
    #   The maximum number of messages to return. Amazon SQS never returns
    #   more messages than this value (however, fewer messages might be
    #   returned). Valid values: 1 to 10. Default: 1.
    # @option options [Integer] :visibility_timeout
    #   The duration (in seconds) that the received messages are hidden from
    #   subsequent retrieve requests after being retrieved by a
    #   `ReceiveMessage` request.
    # @option options [Integer] :wait_time_seconds
    #   The duration (in seconds) for which the call waits for a message to
    #   arrive in the queue before returning. If a message is available, the
    #   call returns sooner than `WaitTimeSeconds`. If no messages are
    #   available and the wait time expires, the call returns successfully
    #   with an empty list of messages.
    # @option options [String] :receive_request_attempt_id
    #   This parameter applies only to FIFO (first-in-first-out) queues.
    #
    #   The token used for deduplication of `ReceiveMessage` calls. If a
    #   networking issue occurs after a `ReceiveMessage` action, and instead
    #   of a response you receive a generic error, you can retry the same
    #   action with an identical `ReceiveRequestAttemptId` to retrieve the
    #   same set of messages, even if their visibility timeout has not yet
    #   expired.
    #
    #   * You can use `ReceiveRequestAttemptId` only for 5 minutes after a
    #     `ReceiveMessage` action.
    #
    #   * When you set `FifoQueue`, a caller of the `ReceiveMessage` action
    #     can provide a `ReceiveRequestAttemptId` explicitly.
    #
    #   * If a caller of the `ReceiveMessage` action doesn't provide a
    #     `ReceiveRequestAttemptId`, Amazon SQS generates a
    #     `ReceiveRequestAttemptId`.
    #
    #   * You can retry the `ReceiveMessage` action with the same
    #     `ReceiveRequestAttemptId` if none of the messages have been modified
    #     (deleted or had their visibility changes).
    #
    #   * During a visibility timeout, subsequent calls with the same
    #     `ReceiveRequestAttemptId` return the same messages and receipt
    #     handles. If a retry occurs within the deduplication interval, it
    #     resets the visibility timeout. For more information, see [Visibility
    #     Timeout][1] in the *Amazon Simple Queue Service Developer Guide*.
    #
    #     If a caller of the `ReceiveMessage` action still processes messages
    #     when the visibility timeout expires and messages become visible,
    #     another worker consuming from the same queue can receive the same
    #     messages and therefore process duplicates. Also, if a consumer whose
    #     message processing time is longer than the visibility timeout tries
    #     to delete the processed messages, the action fails with an error.
    #
    #      To mitigate this effect, ensure that your application observes a
    #     safe threshold before the visibility timeout expires and extend the
    #     visibility timeout as necessary.
    #
    #   * While messages with a particular `MessageGroupId` are invisible, no
    #     more messages belonging to the same `MessageGroupId` are returned
    #     until the visibility timeout expires. You can still receive messages
    #     with another `MessageGroupId` as long as it is also visible.
    #
    #   * If a caller of `ReceiveMessage` can't track the
    #     `ReceiveRequestAttemptId`, no retries work until the original
    #     visibility timeout expires. As a result, delays might occur but the
    #     messages in the queue remain in a strict order.
    #
    #   The length of `ReceiveRequestAttemptId` is 128 characters.
    #   `ReceiveRequestAttemptId` can contain alphanumeric characters (`a-z`,
    #   `A-Z`, `0-9`) and punctuation (`` !"#$%&'()*+,-./:;<=>?@[\]^_`\{|\}~
    #   ``).
    #

    #   ReceiveRequestAttemptId Request Parameter][2] in the *Amazon Simple
    #   Queue Service Developer Guide*.

    #
    #   * Currently, the only supported message system attribute is

    #
    #   The token used for deduplication of sent messages. If a message with a
    #   particular `MessageDeduplicationId` is sent successfully, any messages
    #   sent with the same `MessageDeduplicationId` are accepted successfully
    #   but aren't delivered during the 5-minute deduplication interval. For
    #   more information, see [ Exactly-Once Processing][1] 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

    #   This parameter applies only to FIFO (first-in-first-out) queues.
    #
    #   The tag that specifies that a message belongs to a specific message
    #   group. Messages that belong to the same message group are processed in
    #   a FIFO manner (however, messages in different message groups might be
    #   processed out of order). To interleave multiple ordered streams within
    #   a single queue, use `MessageGroupId` values (for example, session data

    #
    #   * `ReceiveMessage` might return messages with multiple
    #     `MessageGroupId` values. For each `MessageGroupId`, the messages are
    #     sorted by time sent. The caller can't specify a `MessageGroupId`.
    #
    #   The length of `MessageGroupId` is 128 characters. Valid values:
    #   alphanumeric characters and punctuation ``
    #   (!"#$%&'()*+,-./:;<=>?@[\]^_`\{|\}~) ``.
    #
    #   For best practices of using `MessageGroupId`, see [Using the
    #   MessageGroupId Property][1] in the *Amazon Simple Queue Service
    #   Developer Guide*.
    #
    #   `MessageGroupId` is required for FIFO queues. You can't use it for
    #   Standard queues.

    #
    #   The following lists the names, descriptions, and values of the special
    #   request parameters that the `SetQueueAttributes` 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 (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) up 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 representing
    #     seconds, from 60 (1 minute) to 1,209,600 (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][1] 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][4]\:
    #
    #   * `KmsMasterKeyId` - The ID of an AWS-managed customer master key
    #     (CMK) for Amazon SQS or a custom CMK. For more information, see [Key
    #     Terms][5]. 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][6] in the *AWS
    #     Key Management Service API Reference*.
    #
    #   * `KmsDataKeyReusePeriodSeconds` - The length of time, in seconds, for
    #     which Amazon SQS can reuse a [data key][7] 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?][8].
    #
    #   The following attribute applies only to [FIFO (first-in-first-out)
    #   queues][9]\:
    #
    #   * `ContentBasedDeduplication` - Enables content-based deduplication.
    #     For more information, see [Exactly-Once Processing][10] 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.
