    # @deprecated Use [Aws::RDS::Client] #wait_until instead
    #
    # Waiter polls an API operation until a resource enters a desired
    # state.
    #
    # @note The waiting operation is performed on a copy. The original resource
    #   remains unchanged.
    #
    # ## Basic Usage
    #
    # Waiter will polls until it is successful, it fails by
    # entering a terminal state, or until a maximum number of attempts
    # are made.
    #
    #     # polls in a loop until condition is true
    #     resource.wait_until(options) {|resource| condition}
    #
    # ## Example
    #
    #     instance.wait_until(max_attempts:10, delay:5) do |instance|
    #       instance.state.name == 'running'
    #     end
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. The waiting condition is
    # set by passing a block to {#wait_until}:
    #
    #     # poll for ~25 seconds
    #     resource.wait_until(max_attempts:5,delay:5) {|resource|...}
    #
    # ## 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
    #     # poll for 1 hour, instead of a number of attempts
    #     proc = Proc.new do |attempts, response|
    #       throw :failure if Time.now - started_at > 3600
    #     end
    #
    #       # disable max attempts
    #     instance.wait_until(before_wait:proc, max_attempts:nil) {...}
    #
    # ## Handling Errors
    #
    # When a waiter is successful, it returns the Resource. When a waiter
    # fails, it raises an error.
    #
    #     begin
    #       resource.wait_until(...)

    #

    #   * Can't end with a hyphen or contain two consecutive hyphens.
    #
    #   Example: `my-cluster-snapshot2`
    # @option options [String] :kms_key_id
    #   The Amazon Web Services KMS key identifier for an encrypted DB cluster
    #   snapshot. The Amazon Web Services KMS key identifier is the key ARN,
    #   key ID, alias ARN, or alias name for the Amazon Web Services KMS key.
    #
    #   If you copy an encrypted DB cluster snapshot from your Amazon Web
    #   Services account, you can specify a value for `KmsKeyId` to encrypt
    #   the copy with a new KMS key. If you don't specify a value for
    #   `KmsKeyId`, then the copy of the DB cluster snapshot is encrypted with
    #   the same KMS key as the source DB cluster snapshot.
    #
    #   If you copy an encrypted DB cluster snapshot that is shared from
    #   another Amazon Web Services account, then you must specify a value for
    #   `KmsKeyId`.
    #
    #   To copy an encrypted DB cluster snapshot to another Amazon Web
    #   Services Region, you must set `KmsKeyId` to the Amazon Web Services
    #   KMS key identifier you want to use to encrypt the copy of the DB
    #   cluster snapshot in the destination Amazon Web Services Region. KMS
    #   keys are specific to the Amazon Web Services Region that they are
    #   created in, and you can't use KMS keys from one Amazon Web Services
    #   Region in another Amazon Web Services Region.
    #
    #   If you copy an unencrypted DB cluster snapshot and specify a value for
    #   the `KmsKeyId` parameter, an error is returned.
    # @option options [String] :pre_signed_url
    #   When you are copying a DB cluster snapshot from one Amazon Web
    #   Services GovCloud (US) Region to another, the URL that contains a
    #   Signature Version 4 signed request for the `CopyDBClusterSnapshot` API
    #   operation in the Amazon Web Services Region that contains the source
    #   DB cluster snapshot to copy. Use the `PreSignedUrl` parameter when
    #   copying an encrypted DB cluster snapshot from another Amazon Web
    #   Services Region. Don't specify `PreSignedUrl` when copying an
    #   encrypted DB cluster snapshot in the same Amazon Web Services Region.
    #
    #   This setting applies only to Amazon Web Services GovCloud (US)
    #   Regions. It's ignored in other Amazon Web Services Regions.
    #
    #   The presigned URL must be a valid request for the
    #   `CopyDBClusterSnapshot` API operation that can run in the source
    #   Amazon Web Services Region that contains the encrypted DB cluster
    #   snapshot to copy. The presigned URL request must contain the following
    #   parameter values:
    #
    #   * `KmsKeyId` - The KMS key identifier for the KMS key to use to
    #     encrypt the copy of the DB cluster snapshot in the destination
    #     Amazon Web Services Region. This is the same identifier for both the
    #     `CopyDBClusterSnapshot` operation that is called in the destination
    #     Amazon Web Services Region, and the operation contained in the
    #     presigned URL.
    #
    #   * `DestinationRegion` - The name of the Amazon Web Services Region
    #     that the DB cluster snapshot is to 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 Amazon Web Services Region. For example, if you are copying
    #     an encrypted DB cluster snapshot from the us-west-2 Amazon Web
    #     Services Region, then your `SourceDBClusterSnapshotIdentifier` looks
    #     like the following example:
    #     `arn:aws:rds:us-west-2:123456789012:cluster-snapshot:aurora-cluster1-snapshot-20161115`.
    #
    #   To learn how to generate a Signature Version 4 signed request, see [
    #   Authenticating Requests: Using Query Parameters (Amazon Web Services
    #   Signature Version 4)][1] and [ Signature Version 4 Signing
    #   Process][2].
    #
    #   <note markdown="1"> If you are using an Amazon Web Services SDK tool or the CLI, you can
    #   specify `SourceRegion` (or `--source-region` for the CLI) instead of
    #   specifying `PreSignedUrl` manually. Specifying `SourceRegion`
    #   autogenerates a presigned URL that is a valid request for the
    #   operation that can run in the source Amazon Web Services Region.

    # @option options [Boolean] :publicly_accessible
    #   Specifies whether the DB cluster is publicly accessible.
    #
    #   When the DB cluster is publicly accessible, its Domain Name System
    #   (DNS) endpoint resolves to the private IP address from within the DB
    #   cluster's virtual private cloud (VPC). It resolves to the public IP
    #   address from outside of the DB cluster's VPC. Access to the DB
    #   cluster is ultimately controlled by the security group it uses. That
    #   public access is not permitted if the security group assigned to the
    #   DB cluster doesn't permit it.
    #
    #   When the DB cluster isn't publicly accessible, it is an internal DB
    #   cluster with a DNS name that resolves to a private IP address.
    #
    #   Default: The default behavior varies depending on whether
    #   `DBSubnetGroupName` is specified.

    #     attached to it, the DB cluster is public.
    #
    #   If `DBSubnetGroupName` is specified, and `PubliclyAccessible` isn't
    #   specified, the following applies:
    #
    #   * If the subnets are part of a VPC that doesn’t have an internet
    #     gateway attached to it, the DB cluster is private.
    #
    #   * If the subnets are part of a VPC that has an internet gateway

    #   alias ARN, or alias name for the KMS key.
    #
    #   If you don't specify a value for `PerformanceInsightsKMSKeyId`, then
    #   Amazon RDS uses your default KMS key. There is a default KMS key for

    #
    #   <note markdown="1"> By default, this value is set to `open-source-rds-extended-support`,
