type ComponentSet

	// IsRunning when relevant k8s workloads changes, it checks whether the component is running.
	// you can also reconcile the pods of component till the component is Running here.
	IsRunning(ctx context.Context, obj client.Object) (bool, error)

	// PodsReady checks whether all pods of the component are ready.
	// it means the pods are available in StatefulSet or Deployment.
	PodsReady(ctx context.Context, obj client.Object) (bool, error)

	// PodIsAvailable checks whether a pod of the component is available.
	// if the component is Stateless/StatefulSet, the available conditions follows as:
	// 1. the pod is ready.
	// 2. readyTime reached minReadySeconds.
	// if the component is ConsensusSet,it will be available when the pod is ready and labeled with its role.
	PodIsAvailable(pod *corev1.Pod, minReadySeconds int32) bool

	//  calculate the component phase is Failed or Abnormal.
	GetPhaseWhenPodsReadyAndProbeTimeout(pods []*corev1.Pod) (appsv1alpha1.ClusterComponentPhase, appsv1alpha1.ComponentMessageMap)

	// GetPhaseWhenPodsNotReady when the pods of component are not ready, calculate the component phase is Failed or Abnormal.
	// if return an empty phase, means the pods of component are ready and skips it.
