This process is asynchronous. Depending on the number of [Document][google.cloud.discoveryengine.v1beta.Document]s to be deleted, this operation can take hours to complete. Before the delete operation completes, some [Document][google.cloud.discoveryengine.v1beta.Document]s might still be returned by [DocumentService.GetDocument][google.cloud.discoveryengine.v1beta.DocumentService.GetDocument] or [DocumentService.ListDocuments][google.cloud.discoveryengine.v1beta.DocumentService.ListDocuments].

To get a list of the [Document][google.cloud.discoveryengine.v1beta.Document]s to be deleted, set [PurgeDocumentsRequest.force][google.cloud.discoveryengine.v1beta.PurgeDocumentsRequest.force] to false.

Parameters
Name	Description
request	PurgeDocumentsRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Returns
Type	Description
TaskOperationPurgeDocumentsResponsePurgeDocumentsMetadata	A Task containing the RPC response.

Example

// Create client
DocumentServiceClient documentServiceClient = await DocumentServiceClient.CreateAsync();
// Initialize request argument(s)
PurgeDocumentsRequest request = new PurgeDocumentsRequest
{
    ParentAsBranchName = BranchName.FromProjectLocationDataStoreBranch("[PROJECT]", "[LOCATION]", "[DATA_STORE]", "[BRANCH]"),
    Filter = "",
    Force = false,
};
// Make the request
Operation<PurgeDocumentsResponse, PurgeDocumentsMetadata> response = await documentServiceClient.PurgeDocumentsAsync(request);

// Poll until the returned long-running operation is complete
Operation<PurgeDocumentsResponse, PurgeDocumentsMetadata> completedResponse = await response.PollUntilCompletedAsync();
// Retrieve the operation result
PurgeDocumentsResponse 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<PurgeDocumentsResponse, PurgeDocumentsMetadata> retrievedResponse = await documentServiceClient.PollOncePurgeDocumentsAsync(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    PurgeDocumentsResponse retrievedResult = retrievedResponse.Result;
}

ShutdownDefaultChannelsAsync()

public static Task ShutdownDefaultChannelsAsync()

Shuts down any channels automatically created by Create() and CreateAsync(CancellationToken). Channels which weren't automatically created are not affected.

Returns
Type	Description
Task	A task representing the asynchronous shutdown operation.

Remarks

After calling this method, further calls to Create() and CreateAsync(CancellationToken) will create new channels, which could in turn be shut down by another call to this method.
