Overview

An API async client for SageMakerRuntimeHTTP2. To construct an async client, you need to configure a :region and :credentials.

async_client = Aws::SageMakerRuntimeHTTP2::AsyncClient.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

#initialize(options) ⇒ AsyncClient

Returns a new instance of AsyncClient.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    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'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID'].

    • ~/.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 setting ENV['AWS_EC2_METADATA_DISABLED'] to true.

  • :region (required, String) —

Instance Method Details

#invoke_endpoint_with_bidirectional_stream(params = {}) ⇒ Types::InvokeEndpointWithBidirectionalStreamOutput

Invokes a model endpoint with bidirectional streaming capabilities. This operation establishes a persistent connection that allows you to send multiple requests and receive streaming responses from the model in real-time.

Bidirectional streaming is useful for interactive applications such as chatbots, real-time translation, or any scenario where you need to maintain a conversation-like interaction with the model. The connection remains open, allowing you to send additional input and receive responses without establishing a new connection for each request.

For an overview of Amazon SageMaker AI, see How It Works.

Amazon SageMaker AI strips all POST headers except those supported by the API. Amazon SageMaker AI might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.

Calls to InvokeEndpointWithBidirectionalStream are authenticated by using Amazon Web Services Signature Version 4. For information, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 API Reference.

The bidirectional stream maintains the connection until either the client closes it or the model indicates completion. Each request and response in the stream is sent as an event with optional headers for data type and completion state.

Endpoints are scoped to an individual account, and are not public. The URL does not contain the account ID, but Amazon SageMaker AI determines the account ID from the authentication token that is supplied by the caller.

Examples:

Bi-directional EventStream Operation Example

# You can signal input events after the initial request is established. Events
# will be sent to the stream immediately once the stream connection is
# established successfully.

# To signal events, you can call the #signal methods from an
# Aws::SageMakerRuntimeHTTP2::EventStreams::RequestStreamEvent object.
# You must signal events before calling #wait or #join! on the async response.
input_stream = Aws::SageMakerRuntimeHTTP2::EventStreams::RequestStreamEvent.new

async_resp = client.invoke_endpoint_with_bidirectional_stream(
  # params input
  input_event_stream_handler: input_stream
) do |out_stream|
  # register callbacks for events
  out_stream.on_payload_part_event do |event|
    event # => Aws::SageMakerRuntimeHTTP2::Types::PayloadPart
  end
  out_stream.on_model_stream_error_event do |event|
    event # => Aws::SageMakerRuntimeHTTP2::Types::ModelStreamError
  end
  out_stream.on_internal_stream_failure_event do |event|
    event # => Aws::SageMakerRuntimeHTTP2::Types::InternalStreamFailure
  end
end
# => Aws::Seahorse::Client::AsyncResponse

# signal events
input_stream.signal_payload_part_event(
  # ...
)

# make sure to signal :end_stream at the end
input_stream.signal_end_stream

# wait until stream is closed before finalizing the sync response
resp = async_resp.wait

# Or close the stream and finalize sync response immediately
resp = async_resp.join!

# You can also provide an Aws::SageMakerRuntimeHTTP2::EventStreams::ResponseStreamEvent object
# to register callbacks before initializing the request instead of processing
# from the request block.
output_stream = Aws::SageMakerRuntimeHTTP2::EventStreams::ResponseStreamEvent.new

# register callbacks for output events
output_stream.on_payload_part_event do |event|
  event # => Aws::SageMakerRuntimeHTTP2::Types::PayloadPart
end
output_stream.on_model_stream_error_event do |event|
  event # => Aws::SageMakerRuntimeHTTP2::Types::ModelStreamError
end
output_stream.on_internal_stream_failure_event do |event|
  event # => Aws::SageMakerRuntimeHTTP2::Types::InternalStreamFailure
end
output_stream.on_error_event do |event|
  # catch unmodeled error event in the stream
  raise event
  # => Aws::Errors::EventError
  # event.event_type => :error
  # event.error_code => String
  # event.error_message => String
end

async_resp = client.invoke_endpoint_with_bidirectional_stream(
  # params input
  input_event_stream_handler: input_stream,
  output_event_stream_handler: output_stream
)
resp = async_resp.join!

# You can also iterate through events after the response is complete.
# Events are available at
resp.body # => Enumerator

Request syntax with placeholder values


async_resp = async_client.invoke_endpoint_with_bidirectional_stream({
  endpoint_name: "InvokeEndpointWithBidirectionalStreamInputEndpointNameString", # required
  input_event_stream_hander: EventStreams::RequestStreamEvent.new,
  target_variant: "InvokeEndpointWithBidirectionalStreamInputTargetVariantString",
  model_invocation_path: "InvokeEndpointWithBidirectionalStreamInputModelInvocationPathString",
  model_query_string: "InvokeEndpointWithBidirectionalStreamInputModelQueryStringString",
})
# => Seahorse::Client::AsyncResponse
async_resp.wait
# => Seahorse::Client::Response
# Or use async_resp.join!

Response structure


# All events are available at resp.body:
resp.body #=> Enumerator
resp.body.event_types #=> [:payload_part, :model_stream_error, :internal_stream_failure]

# For :payload_part event available at #on_payload_part_event callback and response eventstream enumerator:
event.bytes #=> String
event.data_type #=> String
event.completion_state #=> String
event.p #=> String

# For :model_stream_error event available at #on_model_stream_error_event callback and response eventstream enumerator:
event.message #=> String
event.error_code #=> String

# For :internal_stream_failure event available at #on_internal_stream_failure_event callback and response eventstream enumerator:
event.message #=> String

resp.invoked_production_variant #=> String
