Method: googleapis.compute.v1.regionOperations.wait

Waits for the specified Operation resource to return as DONE or for the request to approach the 2 minute deadline, and retrieves the specified Operation resource. This method differs from the GET method in that it waits for no more than the default deadline (2 minutes) and then returns the current state of the operation, which might be DONE or still in progress. This method is called on a best-effort basis. Specifically: - In uncommon cases, when the server is overloaded, the request might return before the default deadline is reached, or might return after zero seconds. - If the default deadline is reached, there is no guarantee that the operation is actually done when the method returns. Be prepared to retry if the operation is not DONE.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field. See the Connectors reference.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.

The polling policy for the long-running operation can be configured. To set the connector-specific parameters (connector_params), refer to Invoke a connector call.
