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 Google Cloud 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.

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.
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.

NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users/*/operations. To override the binding, API services can add a binding such as "/v1/{name=users/*}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

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 (https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.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 may be set. Some services might not provide the result. result can be only one of the following:
error

Status (/distributed-cloud/hosted/docs/latest/gdch/apis/vertex-ai/translation/rpc/google.rpc#google.rpc.Status)

The error result of the operation in case of failure or cancellation.
response

Any (https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Any)

The normal response of the operation in case of success. 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.
