1.0.0
Initial release.
Buffer Operator is a Kubernetes cluster resource buffer pool manager that reserves node resources and enables fast scale-out through the placeholder Pod mechanism. When a business Pod is created, it can immediately preempt placeholder Pod resources to achieve second-level startup.
Core features: placeholder Pod resource reservation, NodeAnchor node anchoring to prevent CA mis-scaling, DaemonSet/Static Pod II, multiple buffer policies (percentage/absolute value), scale-out/in cooldown mechanism, and OpenTelemetry observability.
Requires Kubernetes 1.24 or later
