Class ModelServiceClient

java.lang.Object
com.google.cloud.retail.v2.ModelServiceClient
All Implemented Interfaces:
BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class ModelServiceClient extends Object implements BackgroundResource
Service Description: Service for performing CRUD operations on models. Recommendation models contain all the metadata necessary to generate a set of models for the `Predict()` API. A model is queried indirectly via a ServingConfig, which associates a model with a given Placement (e.g. Frequently Bought Together on Home Page).

This service allows you to do the following:

  • Initiate training of a model.
  • Pause training of an existing model.
  • List all the available models along with their metadata.
  • Control their tuning schedule.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (ModelServiceClient modelServiceClient = ModelServiceClient.create()) {
   ModelName name = ModelName.of("[PROJECT]", "[LOCATION]", "[CATALOG]", "[MODEL]");
   Model response = modelServiceClient.getModel(name);
 }

Note: close() needs to be called on the ModelServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

CreateModel

Creates a new model.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createModelAsync(CreateModelRequest request)

Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service.

  • createModelAsync(CatalogName parent, Model model)

  • createModelAsync(String parent, Model model)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of ModelServiceSettings to create(). For example:

To customize credentials: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ModelServiceSettings modelServiceSettings =
     ModelServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ModelServiceClient modelServiceClient = ModelServiceClient.create(modelServiceSettings);

To customize the endpoint: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ModelServiceSettings modelServiceSettings =
     ModelServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 ModelServiceClient modelServiceClient = ModelServiceClient.create(modelServiceSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ModelServiceSettings modelServiceSettings = ModelServiceSettings.newHttpJsonBuilder().build();
 ModelServiceClient modelServiceClient = ModelServiceClient.create(modelServiceSettings);
