Operations

Manages long-running operations with an API service.

When an API method normally takes long time to complete, it can be designed to return Operation to the client, and the client can use this interface to receive the real response asynchronously by polling the operation resource, or pass the operation resource to another API (such as Pub/Sub API) to receive the response. Any API service that returns long-running operations should implement the Operations interface so developers can have a consistent client experience.

CancelOperation

rpc CancelOperation(CancelOperationRequest) returns (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 Operations.GetOperation 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 Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED. Authorization scopes Requires the following OAuth scope: https://www.googleapis.com/auth/cloud-platform For more information, see the Authentication Overview. IAM Permissions Requires the following IAM permission on the name resource: livestream.operations.cancel For more information, see the IAM documentation.

DeleteOperation

rpc DeleteOperation(DeleteOperationRequest) returns (Empty) Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Authorization scopes Requires the following OAuth scope: https://www.googleapis.com/auth/cloud-platform For more information, see the Authentication Overview. IAM Permissions Requires the following IAM permission on the name resource: livestream.operations.delete For more information, see the IAM documentation.

GetOperation

rpc GetOperation(GetOperationRequest) returns (Operation) Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service. Authorization scopes Requires the following OAuth scope: https://www.googleapis.com/auth/cloud-platform For more information, see the Authentication Overview. IAM Permissions Requires the following IAM permission on the name resource: livestream.operations.get For more information, see the IAM documentation.

ListOperations

rpc ListOperations(ListOperationsRequest) returns (ListOperationsResponse) Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED. Authorization scopes Requires the following OAuth scope: https://www.googleapis.com/auth/cloud-platform For more information, see the Authentication Overview. IAM Permissions Requires the following IAM permission on the name resource: livestream.operations.list For more information, see the IAM documentation.

WaitOperation

rpc WaitOperation(WaitOperationRequest) returns (Operation) Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state. If the operation is already done, the latest state is immediately returned. If the timeout specified is greater than the default HTTP/RPC timeout, the HTTP/RPC timeout is used. If the server does not support this method, it returns google.rpc.Code.UNIMPLEMENTED. Note that this method is on a best-effort basis. It may return the latest state before the specified timeout (including immediately), meaning even an immediate response is no guarantee that the operation is done. Authorization scopes Requires the following OAuth scope: https://www.googleapis.com/auth/cloud-platform For more information, see the Authentication Overview.

CancelOperationRequest

The request message for Operations.CancelOperation.

Fields
name	string The name of the operation resource to be cancelled.

DeleteOperationRequest

The request message for Operations.DeleteOperation.

Fields
name	string The name of the operation resource to be deleted.

GetOperationRequest

The request message for Operations.GetOperation.

Fields
name	string The name of the operation resource.

ListOperationsRequest

The request message for Operations.ListOperations.

Fields
name	string The name of the operation's parent resource.
filter	string The standard list filter.
page_size	int32 The standard list page size.
page_token	string The standard list page token.

ListOperationsResponse

The response message for Operations.ListOperations.

Fields
operations[]	Operation A list of operations that matches the specified filter in the request.
next_page_token	string The standard List next-page token.

Operation

This resource represents a long-running operation that is the result of a network API call.

Fields
name	string The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}.
metadata	Any Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.
done	bool If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
Union field result. The operation result, which can be either an error or a valid response. If done == false, neither error nor response is set. If done == true, exactly one of error or response can be set. Some services might not provide the result. result can be only one of the following:
error	Status The error result of the operation in case of failure or cancellation.
response	Any The normal, successful response of the operation. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.

WaitOperationRequest

The request message for Operations.WaitOperation.

Fields
name	string The name of the operation resource to wait on.
timeout	Duration The maximum duration to wait before timing out. If left blank, the wait will be at most the time permitted by the underlying HTTP/RPC protocol. If RPC context deadline is also specified, the shorter one will be used.
