public class DataprocMetastoreFederationClient implements BackgroundResource

Service Description: Configures and manages metastore federation services. Dataproc Metastore Federation Service allows federating a collection of backend metastores like BigQuery, Dataplex Lakes, and other Dataproc Metastores. The Federation Service exposes a gRPC URL through which metadata from the backend metastores are served at query time.

The Dataproc Metastore Federation API defines the following resource model:

• The service works with a collection of Google Cloud projects.
• Each project has a collection of available locations.
• Each location has a collection of federations.
• Dataproc Metastore Federations are resources with names of the form: projects/{project_number}/locations/{location_id}/federations/{federation_id}.

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 (DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create()) {
   FederationName name = FederationName.of("[PROJECT]", "[LOCATION]", "[FEDERATION]");
   Federation response = dataprocMetastoreFederationClient.getFederation(name);
 }
 

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

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns 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 DataprocMetastoreFederationSettings 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
 DataprocMetastoreFederationSettings dataprocMetastoreFederationSettings =
     DataprocMetastoreFederationSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create(dataprocMetastoreFederationSettings);
 

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
 DataprocMetastoreFederationSettings dataprocMetastoreFederationSettings =
     DataprocMetastoreFederationSettings.newBuilder().setEndpoint(myEndpoint).build();
 DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create(dataprocMetastoreFederationSettings);
 

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
 DataprocMetastoreFederationSettings dataprocMetastoreFederationSettings =
     DataprocMetastoreFederationSettings.newHttpJsonBuilder().build();
 DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create(dataprocMetastoreFederationSettings);

updateFederationAsync(Federation federation, FieldMask updateMask)

public final OperationFuture<Federation,OperationMetadata> updateFederationAsync(Federation federation, FieldMask updateMask)

Updates the fields of a federation.

Sample code:

 // 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

   Federation response =
       dataprocMetastoreFederationClient.updateFederationAsync(federation, updateMask).get();
 }
 

Parameters

Name	Description
federation	Federation Required. The metastore federation to update. The server only merges fields in the service if they are specified in update_mask. The metastore federation's name field is used to identify the metastore service to be updated.
updateMask	FieldMask Required. A field mask used to specify the fields to be overwritten in the metastore federation resource by the update. Fields specified in the update_mask are relative to the resource (not to the full request). A field is overwritten if it is in the mask.

Returns
