Returns:

The resource is updated in api server if the return value is present within Optional. This the common use cases. However in cases, for example the operator is restarted, and we don't want to have an update call to k8s api to be made unnecessarily, by returning an empty Optional this update can be skipped. However we will always call an update if there is no finalizer on object and its not marked for deletion.
