Kubernetes v1.36 adds the route_controller_route_sync_total metric to Cloud Controller Manager for A/B testing watch-based route reconciliation.
- •Introduces CloudControllerManagerWatchBasedRoutesReconciliation feature gate that switches from fixed-interval polling to event-driven reconciliation
- •Reduces unnecessary API calls to infrastructure providers and relieves pressure on rate-limited APIs
- •With feature gate disabled: metric increments continuously (e.g., 60 times per 10 minutes of inactivity)
- •With feature gate enabled: metric only increments when nodes actually change, significantly reducing unnecessary syncs
- •Operators can validate efficiency gains by comparing route_controller_route_sync_total metrics across different feature gate states
