    # @overload initialize(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::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    #       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::ProcessCredentials` - Used for loading credentials from a
    #       process that outputs to stdout.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.

    #       from the Cognito Identity service.
    #
    #     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.

    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2/ECS IMDS instance profile - When used by default, the timeouts
    #       are very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts. Instance profile credential
    #       fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED']
    #       to true.

    #
    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file

    #     Some predefined functions can be referenced by name - :none, :equal, :full,
    #     otherwise a Proc that takes and returns a number. This option is only used
    #     in the `legacy` retry mode.
    #
    #     @see https://www.awsarchitectureblog.com/2015/03/backoff.html
    #

    #
    #     * `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

    #     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::TokenProvider] :token_provider

    #       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`

    #     `Timeout::Error`.
    #
    #   @option options [Float] :http_read_timeout (60) The default
    #     number of seconds to wait for response data.  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_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] :ssl_timeout (nil) Sets the SSL timeout
    #     in seconds.
    #

    #
    #   @option options [String] :ssl_ca_bundle Full path to the SSL
    #     certificate authority bundle file that should be used when
    #     verifying peer certificates.  If you do not pass

    #     will be used if available.
    #
    #   @option options [String] :ssl_ca_directory Full path of the
    #     directory that contains the unbundled SSL certificate
    #     authority files for verifying peer certificates.  If you do
    #     not pass `:ssl_ca_bundle` or `:ssl_ca_directory` the the

    #   The maximum depth a query can have in a single request. Depth refers
    #   to the amount of nested levels allowed in the body of query. The
    #   default value is `0` (or unspecified), which indicates there's no
    #   depth limit. If you set a limit, it can be between `1` and `75` nested
    #   levels. This field will produce a limit error if the operation falls
    #   out of bounds.
    #
    #   Note that fields can still be set to nullable or non-nullable. If a
    #   non-nullable field produces an error, the error will be thrown upwards
    #   to the first nullable field available.
    #
    # @option params [Integer] :resolver_count_limit
    #   The maximum number of resolvers that can be invoked in a single

    #
    #   A resolver uses a request mapping template to convert a GraphQL

    #   templates are written in Apache Velocity Template Language (VTL).

    #     resolver to invoke a series of `Function` objects in a serial

    #   specified, code must also be specified.
    #
    # @option params [String] :code
    #   The `resolver` code that contains the request and response functions.
