batchReadFeatureValues method

Future<Operation<BatchReadFeatureValuesResponse, BatchReadFeatureValuesOperationMetadata>> batchReadFeatureValues(
  1. BatchReadFeatureValuesRequest request
)

Batch reads Feature values from a Featurestore.

This API enables batch reading Feature values, where each read instance in the batch may read Feature values of entities from one or more EntityTypes. Point-in-time correctness is guaranteed for Feature values of each read instance as of each instance's read timestamp.

Throws a http.ClientException if there were problems communicating with the API service. Throws a StatusException if the API failed with a Status message. Throws a ServiceException for any other failure.

Returns an Operation representing the status of the long-running operation.

When complete, Operation.done will be true. If successful, Operation.responseAsMessage will contain the operation's result.

    _host,
    '/v1beta1/${request.featurestore}:batchReadFeatureValues',
  );
  final response = await _client.post(url, body: request);
  return Operation.fromJson(
    response,
    OperationHelper(
      BatchReadFeatureValuesResponse.fromJson,
      BatchReadFeatureValuesOperationMetadata.fromJson,
