Class DataFusionClient (1.55.0)

GitHub RepositoryProduct ReferenceREST Documentation

Service Description: Service for creating and managing Data Fusion instances. Data Fusion enables ETL developers to build code-free, data integration pipelines via a point-and-click UI.

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 (DataFusionClient dataFusionClient = DataFusionClient.create()) {
   GetInstanceRequest request =
       GetInstanceRequest.newBuilder()
           .setName(InstanceName.of("[PROJECT]", "[LOCATION]", "[INSTANCE]").toString())
           .build();
   Instance response = dataFusionClient.getInstance(request);
 }

Note: close() needs to be called on the DataFusionClient 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

ListAvailableVersions

Lists possible versions for Data Fusion instances in the specified project and location.

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

  • listAvailableVersions(ListAvailableVersionsRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listAvailableVersions(LocationName parent)

  • listAvailableVersions(String parent)

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

  • listAvailableVersionsPagedCallable()

  • listAvailableVersionsCallable()

ListInstances

Lists Data Fusion instances in the specified project and location.

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

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 DataFusionSettings 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
 DataFusionSettings dataFusionSettings =
     DataFusionSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DataFusionClient dataFusionClient = DataFusionClient.create(dataFusionSettings);

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
 DataFusionSettings dataFusionSettings =
     DataFusionSettings.newBuilder().setEndpoint(myEndpoint).build();
 DataFusionClient dataFusionClient = DataFusionClient.create(dataFusionSettings);

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
 DataFusionSettings dataFusionSettings = DataFusionSettings.newHttpJsonBuilder().build();
 DataFusionClient dataFusionClient = DataFusionClient.create(dataFusionSettings);

 }
Parameters
Name Description
instance Instance

Required. The instance resource that replaces the resource on the server. Currently, Data Fusion only allows replacing labels, options, and stack driver settings. All other fields will be ignored.
updateMask FieldMask

Field mask is used to specify the fields that the update will overwrite in an instance resource. The fields specified in the update_mask are relative to the resource, not the full request. A field will be overwritten if it is in the mask. If the user does not provide a mask, all the supported fields (labels, options, and version currently) will be overwritten.
