All Implemented Interfaces:
BackgroundResource, AutoCloseable
@BetaApi @Generated("by gapic-generator-java") public class DataprocMetastoreFederationClient extends Object 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().

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);

    • testIamPermissionsCallable

      public final UnaryCallable<TestIamPermissionsRequest,TestIamPermissionsResponse> testIamPermissionsCallable()
      Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a `NOT_FOUND` error.

      Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.

      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
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (DataprocMetastoreFederationClient dataprocMetastoreFederationClient =
     DataprocMetastoreFederationClient.create()) {

           .setResource(
               BackupName.of("[PROJECT]", "[LOCATION]", "[SERVICE]", "[BACKUP]").toString())
           .addAllPermissions(new ArrayList<String>())
           .build();
   ApiFuture<TestIamPermissionsResponse> future =
       dataprocMetastoreFederationClient.testIamPermissionsCallable().futureCall(request);
   // Do something.
