Class ModelServiceClient (2.31.0-rc)

Model Service for BigQuery ML.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

GetModel(std::string const &, std::string const &, std::string const &, Options)

Gets the specified model resource by model ID.

Parameters
Name	Description
`project_id`	`std::string const &` Required. Project ID of the requested model.
`dataset_id`	`std::string const &` Required. Dataset ID of the requested model.
`model_id`	`std::string const &` Required. Model ID of the requested model.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Model >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Model) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

GetModel(google::cloud::bigquery::v2::GetModelRequest const &, Options)

Gets the specified model resource by model ID.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::GetModelRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.GetModelRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Model >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Model) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

ListModels(std::string const &, std::string const &, google::protobuf::UInt32Value const &, Options)

Lists all models in the specified dataset.

Requires the READER dataset role. After retrieving the list of models, you can get information about a particular model by calling the models.get method.

Parameters
Name	Description
`project_id`	`std::string const &` Required. Project ID of the models to list.
`dataset_id`	`std::string const &` Required. Dataset ID of the models to list.
`max_results`	`google::protobuf::UInt32Value const &` The maximum number of results to return in a single response page. Leverage the page tokens to iterate through the entire collection.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< google::cloud::bigquery::v2::Model >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.bigquery.v2.Model, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

ListModels(google::cloud::bigquery::v2::ListModelsRequest, Options)

Lists all models in the specified dataset.

Requires the READER dataset role. After retrieving the list of models, you can get information about a particular model by calling the models.get method.

Parameters
Name	Description
`request`	`google::cloud::bigquery::v2::ListModelsRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.bigquery.v2.ListModelsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

`model`	`google::cloud::bigquery::v2::Model const &` Required. Patched model. Follows RFC5789 patch semantics. Missing fields are not updated. To clear a field, explicitly set to default value.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::bigquery::v2::Model >`	the result of the RPC. The response message type (google.cloud.bigquery.v2.Model) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.
