    # @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
    #   The AWS region to connect to.  The configured `:region` is
    #   used to determine the service `:endpoint`. When not passed,
    #   a default `:region` is search for in the following locations:
    #
    #   * `Aws.config[:region]`
    #   * `ENV['AWS_REGION']`
    #   * `ENV['AMAZON_REGION']`
    #   * `ENV['AWS_DEFAULT_REGION']`
    #   * `~/.aws/credentials`
    #   * `~/.aws/config`
    #
    # @option options [String] :access_key_id
    #
    # @option options [Boolean] :convert_params (true)
    #   When `true`, an attempt is made to coerce request parameters into
    #   the required types.
    #
    # @option options [String] :endpoint
    #   The client endpoint is normally constructed from the `:region`
    #   option. You should only configure an `:endpoint` when connecting
    #   to test endpoints. This should be avalid HTTP(S) URI.
    #
    # @option options [Aws::Log::Formatter] :log_formatter (Aws::Log::Formatter.default)
    #   The log formatter.
    #
    # @option options [Symbol] :log_level (:info)
    #   The log level to send messages to the `:logger` at.
    #
    # @option options [Logger] :logger
    #   The Logger instance to send log messages to.  If this option
    #   is not set, logging will be disabled.
    #
    # @option options [String] :profile ("default")
    #   Used when loading credentials from the shared credentials file
    #   at HOME/.aws/credentials.  When not specified, 'default' is used.
    #
    # @option options [Float] :retry_base_delay (0.3)
    #   The base delay in seconds used by the default backoff function.
    #
    # @option options [Symbol] :retry_jitter (:none)
    #   A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number.
    #
    #   @see https://www.awsarchitectureblog.com/2015/03/backoff.html
    #
    # @option options [Integer] :retry_limit (3)
    #   The maximum number of times to retry failed requests.  Only
    #   ~ 500 level server errors and certain ~ 400 level client errors
    #   are retried.  Generally, these are throttling errors, data
    #   checksum errors, networking errors, timeout errors and auth
    #   errors from expired credentials.
    #
    # @option options [Integer] :retry_max_delay (0)
    #   The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function.
    #
    # @option options [String] :secret_access_key
    #
    # @option options [String] :session_token
    #
    # @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.
    #
    #   ** Please note ** When response stubbing is enabled, no HTTP
    #   requests are made, and retries are disabled.
    #
    # @option options [Boolean] :validate_params (true)
    #   When `true`, request parameters are validated before
    #   sending the request.

    # @option params [Array<String>] :tag_values
    #   A tag value or values for which you want to return all matching
    #   cluster snapshots that are associated with the specified tag value or
    #   values. For example, suppose that you have snapshots that are tagged
    #   with values called `admin` and `test`. If you specify both of these

    # @option params [String] :snapshot_copy_grant_name
    #   The name of the snapshot copy grant.
    #
    # @option params [Integer] :max_records
    #   The maximum number of response records to return in each call. If the
    #   number of remaining response records exceeds the specified
    #   `MaxRecords` value, a value is returned in a `marker` field of the
    #   response. You can retrieve the next set of records by retrying the
    #   command with the returned marker value.
    #
    #   Default: `100`
    #
    #   Constraints: minimum 20, maximum 100.
    #
    # @option params [String] :marker
    #   An optional parameter that specifies the starting point to return a
    #   set of response records. When the results of a
    #   `DescribeSnapshotCopyGrant` request exceed the value specified in
    #   `MaxRecords`, AWS returns a value in the `Marker` field of the
    #   response. You can retrieve the next set of response records by
    #   providing the returned marker value in the `Marker` parameter and
    #   retrying the request.
    #
    #   Constraints: You can specify either the **SnapshotCopyGrantName**
    #   parameter or the **Marker** parameter, but not both.
    #
    # @option params [Array<String>] :tag_keys
    #   A tag key or keys for which you want to return all matching resources
    #   that are associated with the specified key or keys. For example,
    #   suppose that you have resources tagged with keys called `owner` and
    #   `environment`. If you specify both of these tag keys in the request,
    #   Amazon Redshift returns a response with all resources that have either
    #   or both of these tag keys associated with them.
    #
    # @option params [Array<String>] :tag_values
    #   A tag value or values for which you want to return all matching
    #   resources that are associated with the specified value or values. For
    #   example, suppose that you have resources tagged with values called
    #   `admin` and `test`. If you specify both of these tag values in the
    #   request, Amazon Redshift returns a response with all resources that
    #   have either or both of these tag values associated with them.

    # by specifying an ARN, or you can return all tags for a given type of
    # resource, such as clusters, snapshots, and so on.
    #
    # The following are limitations for `DescribeTags`\:
    #
    # * You cannot specify an ARN and a resource-type value together in the

    # are returned regardless of whether they have tag keys or values
    # associated with them.
    #
    # @option params [String] :resource_name
    #   The Amazon Resource Name (ARN) for which you want to describe the tag

    #
    # @option params [String] :resource_type
    #   The type of resource with which you want to view tags. Valid resource
    #   types are:
    #
    #   * Cluster
    #
    #   * CIDR/IP
    #
    #   * EC2 security group

    #   cluster use RebootCluster.
    #
    #   Default: Uses existing setting.
    #
    #   Constraints: The cluster parameter group must be in the same parameter
    #   group family that matches the cluster version.
    #
    # @option params [Integer] :automated_snapshot_retention_period
    #   The number of days that automated snapshots are retained. If the value
    #   is 0, automated snapshots are disabled. Even if automated snapshots
    #   are disabled, you can still create manual snapshots when you want with
    #   CreateClusterSnapshot.
    #
    #   If you decrease the automated snapshot retention period from its
    #   current value, existing automated snapshots that fall outside of the
    #   new retention period will be immediately deleted.

    #   Constraints: Must be a value from 0 to 35.
    #
    # @option params [String] :preferred_maintenance_window
    #   The weekly time range (in UTC) during which system maintenance can
    #   occur, if necessary. If system maintenance is necessary during the
    #   window, it may result in an outage.
    #
    #   This maintenance window change is made immediately. If the new
    #   maintenance window indicates the current time, there must be at least
    #   120 minutes between the current time and end of the window in order to
    #   ensure that pending changes are applied.
    #
    #   Default: Uses existing setting.
    #
    #   Format: ddd:hh24:mi-ddd:hh24:mi, for example `wed:07:30-wed:08:00`.
    #
    #   Valid Days: Mon \| Tue \| Wed \| Thu \| Fri \| Sat \| Sun
    #
    #   Constraints: Must be at least 30 minutes.
    #
    # @option params [String] :cluster_version
    #   The new version number of the Amazon Redshift engine to upgrade to.
    #
    #   For major version upgrades, if a non-default cluster parameter group
    #   is currently in use, a new cluster parameter group in the cluster
    #   parameter group family for the new version must be specified. The new
    #   cluster parameter group can be the default for that cluster parameter
    #   group family. For more information about parameters and parameter
    #   groups, go to [Amazon Redshift Parameter Groups][1] in the *Amazon
    #   Redshift Cluster Management Guide*.
    #

    #   If `true`, major version upgrades will be applied automatically to the
    #   cluster during the maintenance window.
    #
    #   Default: `false`
    #
    # @option params [String] :hsm_client_certificate_identifier
    #   Specifies the name of the HSM client certificate the Amazon Redshift
    #   cluster uses to retrieve the data encryption keys stored in an HSM.
    #
    # @option params [String] :hsm_configuration_identifier
    #   Specifies the name of the HSM configuration that contains the
    #   information the Amazon Redshift cluster can use to retrieve and store
    #   keys in an HSM.
    #
    # @option params [String] :new_cluster_identifier
    #   The new identifier for the cluster.

    #
    #   * Alphabetic characters must be lowercase.
    #
    #   * First character must be a letter.
    #
    #   * Cannot end with a hyphen or contain two consecutive hyphens.
    #
    #   * Must be unique for all clusters within an AWS account.
    #
    #   Example: `examplecluster`
    #
    # @option params [Boolean] :publicly_accessible
    #   If `true`, the cluster can be accessed from a public network. Only
    #   clusters in VPCs can be set to be publicly available.
    #
    # @option params [String] :elastic_ip
    #   The Elastic IP (EIP) address for the cluster.
    #
    #   Constraints: The cluster must be provisioned in EC2-VPC and
    #   publicly-accessible through an Internet gateway. For more information
    #   about provisioning clusters in EC2-VPC, go to [Supported Platforms to
    #   Launch Your Cluster][1] in the Amazon Redshift Cluster Management

    #
    # @option params [Boolean] :enhanced_vpc_routing
    #   An option that specifies whether to create the cluster with enhanced
    #   VPC routing enabled. To create a cluster that uses enhanced VPC
    #   routing, the cluster must be in a VPC. For more information, see
    #   [Enhanced VPC Routing][1] in the Amazon Redshift Cluster Management
    #   Guide.
    #
    #   If this option is `true`, enhanced VPC routing is enabled.

    #
    # @option params [String] :maintenance_track_name
    #   The name for the maintenance track that you want to assign for the
    #   cluster. This name change is asynchronous. The new track name stays in
    #   the `PendingModifiedValues` for the cluster until the next maintenance
    #   window. When the maintenance track changes, the cluster is switched to
    #   the latest cluster release available for the maintenance track. At
    #   this point, the maintenance track name is applied.

    #   case, you can choose to restore into another DS node type of the same
    #   size. For example, you can restore ds1.8xlarge into ds2.8xlarge, or
    #   ds1.xlarge into ds2.xlarge. If you have a DC instance type, you must
    #   restore into that same instance type and size. In other words, you can
    #   only restore a dc1.large instance type into another dc1.large instance
    #   type or dc2.large instance type. You can't restore dc1.8xlarge to
    #   dc2.8xlarge. First restore to a dc1.8xlareg cluster, then resize to a
    #   dc2.8large cluster. For more information about node types, see [ About
    #   Clusters and Nodes][1] in the *Amazon Redshift Cluster Management

    # 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.waiter_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(...)

    #     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 |

    # | snapshot_available | {#describe_cluster_snapshots} | 15       | 20            |
    #
    # @raise [Errors::FailureStateError] Raised when the waiter terminates
    #   because the waiter has entered a state that it will not transition
    #   out of, preventing success.
    #

    #   maximum number of attempts have been made, and the waiter is not
    #   yet successful.
