Asynchronous operations
Any operations that change the state of a resource (create, change, or delete it) are asynchronous signature operations. This means that when they are called, the server returns the Operation object.
The Operation
object contains information about the operation: its status, ID, creation date, and more. You can use this object for operation status monitoring. The operation status is displayed in the done
field. If the field value is true
, the operation is completed; otherwise, the operation is still in progress.
When calling the Create
method, the returned Operation
object will contain the ID of the resource being created, even if the operation is not complete yet. Using this ID, you can access the resource via the Get
or List
method.
If an error occurs while performing an asynchronous operation, the server aborts all running procedures and returns the system to the previous state. The resources created during the operation are deleted. The Operation
object has the additional error
field describing the error. However, the operation is considered completed only when the system entirely rolls back to the previous state. For more information, see the Operation object description.
