    #
    #   @option options [Array<Seahorse::Client::Plugin>] :plugins ([]])
    #     A list of plugins to apply to the client. Each plugin is either a
    #     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`.
    #
    #     * `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.
    #
    #     * `Aws::ECSCredentials` - Used for loading credentials from
    #       instances running in ECS.
    #
    #     * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    #       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`, `:session_token`, and
    #       `:account_id` options.
    #
    #     * `ENV['AWS_ACCESS_KEY_ID']`, `ENV['AWS_SECRET_ACCESS_KEY']`,

    #
    #     * `~/.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::InstanceProfileCredentials` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts. Instance profile credential fetching can be disabled by

    #     * `Aws.config[:region]`
    #     * `ENV['AWS_REGION']`
    #     * `ENV['AMAZON_REGION']`
    #     * `ENV['AWS_DEFAULT_REGION']`
    #     * `~/.aws/credentials`

    #
    #   @option options [Boolean] :adaptive_retry_wait_to_fill (true)
    #     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:
    #     `sigv4`, `sigv4a`, `httpBearerAuth`, and `noAuth`. When set using `ENV['AWS_AUTH_SCHEME_PREFERENCE']` or in
    #     shared config as `auth_scheme_preference`, the value should be a comma-separated list.
    #
    #   @option options [Boolean] :client_side_monitoring (false)
    #     When `true`, client-side metrics will be collected for all API requests from
    #     this client.
    #
    #   @option options [String] :client_side_monitoring_client_id ("")
    #     Allows you to provide an identifier for this client which will be attached 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 [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

    #
    #     * `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

    #     * `~/.aws/config`
    #
    #   @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.

    #     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

    #       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.

    #   @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.

    #     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 name of the ledger that you want to create. The name must be
    #   unique among all of the ledgers in your Amazon Web Services account in
    #   the current Region.
    #
    #   Naming constraints for ledger names are defined in [Quotas in Amazon
    #   QLDB][1] in the *Amazon QLDB Developer Guide*.

    # @option params [Hash<String,String>] :tags
    #   The key-value pairs to add as tags to the ledger that you want to
    #   create. Tag keys are case sensitive. Tag values are case sensitive and
    #   can be null.
    #
    # @option params [required, String] :permissions_mode
    #   The permissions mode to assign to the ledger that you want to create.
    #   This parameter can have one of the following values:
    #
    #   * `ALLOW_ALL`: A legacy permissions mode that enables access control
    #     with API-level granularity for ledgers.
    #
    #     This mode allows users who have the `SendCommand` API permission for
    #     this ledger to run all PartiQL commands (hence, `ALLOW_ALL`) on any
    #     tables in the specified ledger. This mode disregards any table-level
    #     or command-level IAM permissions policies that you create for the
    #     ledger.
    #
    #   * `STANDARD`: (*Recommended*) A permissions mode that enables access
    #     control with finer granularity for ledgers, tables, and PartiQL
    #     commands.
    #
    #     By default, this mode denies all user requests to run any PartiQL
    #     commands on any tables in this ledger. To allow PartiQL commands to
    #     run, you must create IAM permissions policies for specific table
    #     resources and PartiQL actions, in addition to the `SendCommand` API
    #     permission for the ledger. For information, see [Getting started
    #     with the standard permissions mode][1] in the *Amazon QLDB Developer
    #     Guide*.
    #
    #   <note markdown="1"> We strongly recommend using the `STANDARD` permissions mode to
    #   maximize the security of your ledger data.

    #
    # @option params [Boolean] :deletion_protection
    #   Specifies whether the ledger is protected from being deleted by any
    #   user. If not defined during ledger creation, this feature is enabled
    #   (`true`) by default.
    #
    #   If deletion protection is enabled, you must first disable it before
    #   you can delete the ledger. You can disable it by calling the
    #   `UpdateLedger` operation to set this parameter to `false`.
    #
    # @option params [String] :kms_key
    #   The key in Key Management Service (KMS) to use for encryption of data
    #   at rest in the ledger. For more information, see [Encryption at
    #   rest][1] in the *Amazon QLDB Developer Guide*.
    #
    #   Use one of the following options to specify this parameter:
    #
    #   * `AWS_OWNED_KMS_KEY`: Use an KMS key that is owned and managed by
    #     Amazon Web Services on your behalf.
    #
    #   * **Undefined**: By default, use an Amazon Web Services owned KMS key.
    #
    #   * **A valid symmetric customer managed KMS key**: Use the specified
    #     symmetric encryption KMS key in your account that you create, own,
    #     and manage.
    #
    #     Amazon QLDB does not support asymmetric keys. For more information,
    #     see [Using symmetric and asymmetric keys][2] in the *Key Management
    #     Service Developer Guide*.
    #
    #   To specify a customer managed KMS key, you can use its key ID, Amazon
    #   Resource Name (ARN), alias name, or alias ARN. When using an alias
    #   name, prefix it with `"alias/"`. To specify a key in a different
    #   Amazon Web Services account, you must use the key ARN or alias ARN.
    #
    #   For example:
    #
    #   * Key ID: `1234abcd-12ab-34cd-56ef-1234567890ab`
    #
    #   * Key ARN:
    #     `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`
    #
    #   * Alias name: `alias/ExampleAlias`
    #
    #   * Alias ARN: `arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias`
    #

    # Updates properties on a ledger.
    #
    # @option params [required, String] :name
    #   The name of the ledger.
    #
    # @option params [Boolean] :deletion_protection
    #   Specifies whether the ledger is protected from being deleted by any
    #   user. If not defined during ledger creation, this feature is enabled
    #   (`true`) by default.
    #
    #   If deletion protection is enabled, you must first disable it before
    #   you can delete the ledger. You can disable it by calling the
    #   `UpdateLedger` operation to set this parameter to `false`.
    #
    # @option params [String] :kms_key
    #   The key in Key Management Service (KMS) to use for encryption of data
    #   at rest in the ledger. For more information, see [Encryption at
    #   rest][1] in the *Amazon QLDB Developer Guide*.
    #
    #   Use one of the following options to specify this parameter:
    #
    #   * `AWS_OWNED_KMS_KEY`: Use an KMS key that is owned and managed by
    #     Amazon Web Services on your behalf.
    #
    #   * **Undefined**: Make no changes to the KMS key of the ledger.
    #
    #   * **A valid symmetric customer managed KMS key**: Use the specified
    #     symmetric encryption KMS key in your account that you create, own,
    #     and manage.
    #
    #     Amazon QLDB does not support asymmetric keys. For more information,
    #     see [Using symmetric and asymmetric keys][2] in the *Key Management
    #     Service Developer Guide*.
    #
    #   To specify a customer managed KMS key, you can use its key ID, Amazon
    #   Resource Name (ARN), alias name, or alias ARN. When using an alias
    #   name, prefix it with `"alias/"`. To specify a key in a different
    #   Amazon Web Services account, you must use the key ARN or alias ARN.
    #
    #   For example:
    #
    #   * Key ID: `1234abcd-12ab-34cd-56ef-1234567890ab`
    #
    #   * Key ARN:
    #     `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`
    #
    #   * Alias name: `alias/ExampleAlias`
    #
    #   * Alias ARN: `arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias`
    #

    # @option params [required, String] :name
    #   The name of the ledger.
    #
    # @option params [required, String] :permissions_mode
    #   The permissions mode to assign to the ledger. This parameter can have
    #   one of the following values:
    #
    #   * `ALLOW_ALL`: A legacy permissions mode that enables access control
    #     with API-level granularity for ledgers.
    #
    #     This mode allows users who have the `SendCommand` API permission for
    #     this ledger to run all PartiQL commands (hence, `ALLOW_ALL`) on any
    #     tables in the specified ledger. This mode disregards any table-level
    #     or command-level IAM permissions policies that you create for the
    #     ledger.
    #
    #   * `STANDARD`: (*Recommended*) A permissions mode that enables access
    #     control with finer granularity for ledgers, tables, and PartiQL
    #     commands.
    #
    #     By default, this mode denies all user requests to run any PartiQL
    #     commands on any tables in this ledger. To allow PartiQL commands to
    #     run, you must create IAM permissions policies for specific table
    #     resources and PartiQL actions, in addition to the `SendCommand` API
    #     permission for the ledger. For information, see [Getting started
    #     with the standard permissions mode][1] in the *Amazon QLDB Developer
    #     Guide*.
    #
