    #     class name or an instance of a plugin class.
    #
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials used for authentication. This can be any class that includes and implements
    #     `Aws::CredentialProvider`, or instance of any one of the following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.

    #       assume a role after providing credentials via the web.
    #
    #     * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    #       access token generated from `aws login`.

    #
    #     * `~/.aws/config`
    #
    #     * EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive.
    #       Construct and pass an instance of `Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts. Instance profile credential fetching can be disabled by

    #     Used only in `adaptive` retry mode.  When true, the request will sleep
    #     until there is sufficent client side capacity to retry the request.
    #     When false, the request will raise a `RetryCapacityNotAvailableError` and will
    #     not retry instead of sleeping.
    #
    #   @option options [Array<String>] :auth_scheme_preference
    #     A list of preferred authentication schemes to use when making a request. Supported values are:

    #
    #   @option options [String, URI::HTTPS, URI::HTTP] :endpoint
    #     Normally you should not configure the `:endpoint` option
    #     directly. This is normally constructed from the `:region`
    #     option. Configuring `:endpoint` is normally reserved for
    #     connecting to test or custom endpoints. The endpoint should

    #     An integer representing the maximum number attempts that will be made for
    #     a single request, including the initial attempt.  For example,
    #     setting this value to 5 will result in a request being retried up to
    #     4 times. Used in `standard` and `adaptive` retry modes.
    #
    #   @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 [String] :request_checksum_calculation ("when_supported")
    #     Determines when a checksum will be calculated for request payloads. Values are:
    #
    #     * `when_supported` - (default) When set, a checksum will be
    #       calculated for all request payloads of operations modeled with the
    #       `httpChecksum` trait where `requestChecksumRequired` is `true` and/or a
    #       `requestAlgorithmMember` is modeled.

    #
    #   @option options [String] :response_checksum_validation ("when_supported")
    #     Determines when checksum validation will be performed on response payloads. Values are:
    #
    #     * `when_supported` - (default) When set, checksum validation is performed on all
    #       response payloads of operations modeled with the `httpChecksum` trait where

    #
    #   @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, auth errors,
    #     endpoint discovery, and errors from expired credentials.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @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. This option is only used in the
    #     `legacy` retry mode.
    #
    #   @option options [String] :retry_mode ("legacy")
    #     Specifies which retry algorithm to use. Values are:
    #

    #       no retry mode is provided.
    #
    #     * `standard` - A standardized set of retry rules across the AWS SDKs.
    #       This includes support for retry quotas, which limit the number of
    #       unsuccessful retries a client can make.
    #
    #     * `adaptive` - An experimental retry mode that includes all the
    #       functionality of `standard` mode along with automatic client side
    #       throttling.  This is a provisional mode that may change behavior
    #       in the future.
    #
    #   @option options [String] :sdk_ua_app_id
    #     A unique and opaque application ID that is appended to the
    #     User-Agent header as app/sdk_ua_app_id. It should have a
    #     maximum length of 50. This variable is sourced from environment
    #     variable AWS_SDK_UA_APP_ID or the shared config profile attribute sdk_ua_app_id.
    #
    #   @option options [String] :secret_access_key

    #     in the following locations:
    #
    #     * `Aws.config[:sigv4a_signing_region_set]`
    #     * `ENV['AWS_SIGV4A_SIGNING_REGION_SET']`
    #     * `~/.aws/config`
    #
    #   @option options [Boolean] :simple_json (false)
    #     Disables request parameter conversion, validation, and formatting.
    #     Also disables response data type conversions. The request parameters
    #     hash must be formatted exactly as the API expects.This option is useful
    #     when you want to ensure the highest level of performance by avoiding
    #     overhead of walking request parameters and response data structures.
    #
    #   @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 [Aws::Telemetry::TelemetryProviderBase] :telemetry_provider (Aws::Telemetry::NoOpTelemetryProvider)
    #     Allows you to provide a telemetry provider, which is used to
    #     emit telemetry data. By default, uses `NoOpTelemetryProvider` which
    #     will not record or emit any telemetry data. The SDK supports the
    #     following telemetry providers:
    #
    #     * OpenTelemetry (OTel) - To use the OTel provider, install and require the
    #     `opentelemetry-sdk` gem and then, pass in an instance of a
    #     `Aws::Telemetry::OTelProvider` for telemetry provider.
    #
    #   @option options [Aws::TokenProvider] :token_provider
    #     Your Bearer token used for authentication. This can be any class that includes and implements
    #     `Aws::TokenProvider`, or instance of any one of the following classes:
    #
    #     * `Aws::StaticTokenProvider` - Used for configuring static, non-refreshing
    #       tokens.
    #
    #     * `Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     When `:token_provider` is not configured directly, the `Aws::TokenProviderChain`
    #     will be used to search for tokens configured for your profile in shared configuration files.
    #
    #   @option options [Boolean] :use_dualstack_endpoint
    #     When set to `true`, dualstack enabled endpoints (with `.aws` TLD)
    #     will be used if available.
    #
    #   @option options [Boolean] :use_fips_endpoint
    #     When set to `true`, fips compatible endpoints will be used if available.
    #     When a `fips` region is used, the region is normalized and this config
    #     is set to `true`.
    #
    #   @option options [Boolean] :validate_params (true)
    #     When `true`, request parameters are validated before
    #     sending the request.
    #
    #   @option options [Aws::SWF::EndpointProvider] :endpoint_provider
    #     The endpoint provider used to resolve endpoints. Any object that responds to
    #     `#resolve_endpoint(parameters)` where `parameters` is a Struct similar to

    #   @option options [Float] :http_continue_timeout (1)
    #     The number of seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has "Expect"
    #     header set to "100-continue".  Defaults to `nil` which  disables this
    #     behaviour.  This value can safely be set per request on the session.
    #
    #   @option options [Float] :http_idle_timeout (5)
    #     The number of seconds a connection is allowed to sit idle before it
    #     is considered stale.  Stale connections are closed and removed from the
    #     pool before making a request.
    #
    #   @option options [Float] :http_open_timeout (15)
    #     The default number of seconds to wait for response data.

    #
    #   @option options [Proc] :on_chunk_received
    #     When a Proc object is provided, it will be used as callback when each chunk
    #     of the response body is received. It provides three arguments: the chunk,
    #     the number of bytes received, and the total number of
    #     bytes in the response (or nil if the server did not send a `content-length`).
    #
    #   @option options [Proc] :on_chunk_sent
    #     When a Proc object is provided, it will be used as callback when each chunk
    #     of the request body is sent. It provides three arguments: the chunk,
    #     the number of bytes read from the body, and the total number of

    #
    #   <note markdown="1"> A task list for this workflow execution must be specified either as a

    #
    # @option params [String] :input
    #   The input for the workflow execution. This is a free form string which
    #   should be meaningful to the workflow you are starting. This `input` is
    #   made available to the new workflow execution in the
    #   `WorkflowExecutionStarted` history event.
    #
    # @option params [String] :execution_start_to_close_timeout
    #   The total duration for this workflow execution. This overrides the
    #   defaultExecutionStartToCloseTimeout specified when registering the
    #   workflow type.
    #
    #   The duration is specified in seconds; an integer greater than or equal
    #   to `0`. Exceeding this limit causes the workflow execution to time
    #   out. Unlike some of the other timeout parameters in Amazon SWF, you
    #   cannot specify a value of "NONE" for this timeout; there is a
    #   one-year max limit on the time that a workflow execution can run.
    #
    #   <note markdown="1"> An execution start-to-close timeout must be specified either through
    #   this parameter or as a default when the workflow type is registered.

    #
    #    </note>
    #
    # @option params [Array<String>] :tag_list
    #   The list of tags to associate with the workflow execution. You can
    #   specify a maximum of 5 tags. You can list workflow executions with a

    #   workflow type using RegisterWorkflowType.
    #
    #   The duration is specified in seconds, an integer greater than or equal
    #   to `0`. You can use `NONE` to specify unlimited duration.
    #
    #   <note markdown="1"> A task start-to-close timeout for this workflow execution must be

    #   of this workflow execution if it is terminated, by calling the
    #   TerminateWorkflowExecution action explicitly or due to an expired
    #   timeout. This policy overrides the default child policy specified when
    #   registering the workflow type using RegisterWorkflowType.
    #
    #   The supported child policies are:
    #
    #   * `TERMINATE` – The child executions are terminated.

    #   * `REQUEST_CANCEL` – A request to cancel is attempted for each child
    #     execution by recording a `WorkflowExecutionCancelRequested` event in
    #     its history. It is up to the decider to take appropriate actions
    #     when it receives an execution history with this event.
    #
    #   * `ABANDON` – No action is taken. The child executions continue to
    #     run.

    # @option params [String] :lambda_role
    #   The IAM role to attach to this workflow execution.
    #
    #   <note markdown="1"> Executions of this workflow type need IAM roles to invoke Lambda

    # **Access Control**
    #
    # You can use IAM policies to control this action's access to Amazon
    # SWF resources as follows:
    #
    # * Use a `Resource` element with the domain name to limit the action to
    #   only specified domains.
    #
    # * Use an `Action` element to allow or deny permission to call this
    #   action.
    #
    # * Constrain the following parameters by using a `Condition` element
    #   with the appropriate keys.
    #
    #   * `workflowType.name`: String constraint. The key is
    #     `swf:workflowType.name`.
    #
    #   * `workflowType.version`: String constraint. The key is
    #     `swf:workflowType.version`.
    #
    # If the caller doesn't have sufficient permissions to invoke the
    # action, or the parameter values fall outside the specified
    # constraints, the action fails. The associated event attribute's
    # `cause` parameter is set to `OPERATION_NOT_PERMITTED`. For details and
    # example IAM policies, see [Using IAM to Manage Access to Amazon SWF
    # Workflows][1] in the *Amazon SWF Developer Guide*.
