Inheritance

object > DataprocMetastoreFederationClient

Namespace

Google.Cloud.Metastore.V1

Assembly

Google.Cloud.Metastore.V1.dll

Remarks

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}.

UpdateFederationAsync(Federation, FieldMask, CallSettings)

public virtual Task<Operation<Federation, OperationMetadata>> UpdateFederationAsync(Federation federation, FieldMask updateMask, CallSettings callSettings = null)

Updates the fields of a federation.

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.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
TaskOperationFederationOperationMetadata

A Task containing the RPC response.
Example 
// Create client
DataprocMetastoreFederationClient dataprocMetastoreFederationClient = await DataprocMetastoreFederationClient.CreateAsync();
// Initialize request argument(s)
Federation federation = new Federation();
FieldMask updateMask = new FieldMask();
// Make the request
Operation<Federation, OperationMetadata> response = await dataprocMetastoreFederationClient.UpdateFederationAsync(federation, updateMask);

// Poll until the returned long-running operation is complete
Operation<Federation, OperationMetadata> completedResponse = await response.PollUntilCompletedAsync();
// Retrieve the operation result
Federation result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<Federation, OperationMetadata> retrievedResponse = await dataprocMetastoreFederationClient.PollOnceUpdateFederationAsync(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    Federation retrievedResult = retrievedResponse.Result;
}
