    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region

    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.

    #   the `KmsKeyId` parameter, an error is returned.
    #
    # @option params [String] :pre_signed_url
    #   The URL that contains a Signature Version 4 signed request for the
    #   `CopyDBClusterSnapshot` API action in the AWS Region that contains the
    #   source DB cluster snapshot to copy. You must use the `PreSignedUrl`
    #   parameter when copying an encrypted DB cluster snapshot from another
    #   AWS Region.
    #
    #   The presigned URL must be a valid request for the
    #   `CopyDBSClusterSnapshot` API action that can be executed in the source
    #   AWS Region that contains the encrypted DB cluster snapshot to be
    #   copied. The presigned URL request must contain the following parameter
    #   values:
    #
    #   * `KmsKeyId` - The AWS KMS key identifier for the key to use to
    #     encrypt the copy of the DB cluster snapshot in the destination AWS
    #     Region. This is the same identifier for both the
    #     `CopyDBClusterSnapshot` action that is called in the destination AWS
    #     Region, and the action contained in the presigned URL.
    #
    #   * `DestinationRegion` - The name of the AWS Region that the DB cluster
    #     snapshot will be created in.
    #
    #   * `SourceDBClusterSnapshotIdentifier` - The DB cluster snapshot
    #     identifier for the encrypted DB cluster snapshot to be copied. This
    #     identifier must be in the Amazon Resource Name (ARN) format for the
    #     source AWS Region. For example, if you are copying an encrypted DB
    #     cluster snapshot from the us-west-2 AWS Region, then your
    #     `SourceDBClusterSnapshotIdentifier` looks like the following
    #     example:
    #     `arn:aws:rds:us-west-2:123456789012:cluster-snapshot:my-cluster-snapshot-20161115`.
    #
    # @option params [Boolean] :copy_tags
    #   Set to `true` to copy all tags from the source DB cluster snapshot to
    #   the target DB cluster snapshot, and otherwise `false`. The default is
    #   `false`.

    #   The AWS KMS key identifier for an encrypted DB cluster.
    #
    #   The AWS KMS key identifier is the Amazon Resource Name (ARN) for the
    #   AWS KMS encryption key. If you are creating a DB cluster using the
    #   same AWS account that owns the AWS KMS encryption key that is used to

    #   of the ARN for the AWS KMS encryption key.
    #
    #   If an encryption key is not specified in `KmsKeyId`\:
    #
    #   * If `ReplicationSourceIdentifier` identifies an encrypted source,
    #     then Amazon DocumentDB uses the encryption key that is used to
    #     encrypt the source. Otherwise, Amazon DocumentDB uses your default

    #     `ReplicationSourceIdentifier` is not specified, Amazon DocumentDB
    #     uses your default encryption key.
    #
    #   AWS KMS creates the default encryption key for your AWS account. Your
    #   AWS account has a different default encryption key for each AWS
    #   Region.
    #
    #   If you create a replica of an encrypted DB cluster in another AWS
    #   Region, you must set `KmsKeyId` to a KMS key ID that is valid in the
    #   destination AWS Region. This key is used to encrypt the replica in
    #   that AWS Region.
    #
    # @option params [Array<String>] :enable_cloudwatch_logs_exports

    #   the new DB cluster, then you can use the AWS KMS key alias instead of
    #   the ARN for the AWS KMS encryption key.
    #
    #   You can restore to a new DB cluster and encrypt the new DB cluster
    #   with an AWS KMS key that is different from the AWS KMS key used to
    #   encrypt the source DB cluster. The new DB cluster is encrypted with
    #   the AWS KMS key identified by the `KmsKeyId` parameter.
    #
    #   If you do not specify a value for the `KmsKeyId` parameter, then the
    #   following occurs:
    #
    #   * If the DB cluster is encrypted, then the restored DB cluster is
    #     encrypted using the AWS KMS key that was used to encrypt the source
    #     DB cluster.
    #
    #   * If the DB cluster is not encrypted, then the restored DB cluster is
    #     not encrypted.
    #
    #   If `DBClusterIdentifier` refers to a DB cluster that is not encrypted,
    #   then the restore request is rejected.

    # Polls an API operation until a resource enters a desired state.
    #
    # ## Basic Usage
    #
    # A waiter will call an API operation until:
    #
    # * It is successful
    # * It enters a terminal state
    # * It makes the maximum number of attempts
    #
    # In between attempts, the waiter will sleep.
    #
    #     # polls in a loop, sleeping between attempts
    #     client.wait_until(waiter_name, params)
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. You can pass
    # configuration as the final arguments hash.
    #
    #     # poll for ~25 seconds
    #     client.wait_until(waiter_name, params, {
    #       max_attempts: 5,
    #       delay: 5,
    #     })
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     client.wait_until(waiter_name, params, {
    #
    #       # disable max attempts
    #       max_attempts: nil,
    #
    #       # poll for 1 hour, instead of a number of attempts
    #       before_wait: -> (attempts, response) do
    #         throw :failure if Time.now - started_at > 3600
    #       end
    #     })
    #
    # ## Handling Errors
    #
    # When a waiter is unsuccessful, it will raise an error.
    # All of the failure errors extend from
    # {Aws::Waiters::Errors::WaiterFailed}.
    #
    #     begin
    #       client.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end
    #
    # ## Valid Waiters
    #
    # The following table lists the valid waiter names, the operations they call,
    # and the default `:delay` and `:max_attempts` values.
    #
    # | waiter_name           | params                   | :delay   | :max_attempts |
