observedGeneration property
ObservedGeneration is the 'Generation' of the Route that was last processed by the controller.
Clients polling for completed reconciliation should poll until observedGeneration = metadata.generation and the Ready condition's status is True or False. Note that providing a TrafficTarget that has latest_revision=True will result in a Route that does not increment either its metadata.generation or its observedGeneration, as new "latest ready" revisions from the Configuration are processed without an update to the Route's spec.
Implementation
core.int? observedGeneration;
