k8s: Kubernetes v1.35: Extended Toleration Operators to Support Numeric Comparisons (Alpha)
Kubernetes Official Blog

Kubernetes v1.35 introduces Extended Toleration Operators (alpha) that add numeric comparison operators Gt and Lt to spec.tolerations. This lets tolerations compare numeric taint values (e.g., failure-probability, gpu-compute-score, disk-iops, cost-per-hour) so schedulers can make threshold-based placement decisions while preserving taint/toleration semantics (centralized node-side policy and eviction via NoExecute). The feature is gated, supports all taint effects, has specific numeric format rules, and is experimental — feedback and further enhancements (CEL, autoscaling integration, graduation) are planned.
