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}. v1beta

Package

@google-cloud/dataproc-metastore

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of DataprocMetastoreFederationClient.

Parameters
Name	Description
opts	ClientOptions
gaxInstance	typeof gax | typeof gax.fallback : loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new DataprocMetastoreFederationClient({fallback: 'rest'}, gax); ```

cancelOperation(request, options, callback)

cancelOperation(request: protos.google.longrunning.CancelOperationRequest, options?: gax.CallOptions | Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} | undefined | null>, callback?: Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} | undefined | null>): Promise<protos.google.protobuf.Empty>;

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an value with a of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
request	protos.google.longrunning.CancelOperationRequest The request object that will be sent.
options	gax.CallOptions | Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} | undefined | null> Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
callback	Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} | undefined | null> The function which will be called with the result of the API call. {Promise} - The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.

Returns
Type	Description
Promise<protos.google.protobuf.Empty>

Example

const client = longrunning.operationsClient();
await client.cancelOperation({name: ''});

checkCreateFederationProgress(name)

checkCreateFederationProgress(name: string): Promise<LROperation<protos.google.cloud.metastore.v1beta.Federation, protos.google.cloud.metastore.v1beta.OperationMetadata>>;

Check the status of the long running operation returned by createFederation().

Parameter
Name	Description
name	string The operation name that will be passed.

Returns
Type	Description
Promise<LROperation<protos.google.cloud.metastore.v1beta.Federation, protos.google.cloud.metastore.v1beta.OperationMetadata>>	{Promise} - The promise which resolves to an object. The decoded operation object has result and metadata field to get information from.
