	// ToClusterPhase indicates that the cluster will enter this phase during the operation.
	ToClusterPhase appsv1alpha1.ClusterPhase

	// MaintainClusterPhaseBySelf indicates whether the operation will maintain cluster/component phase by itself.
	// Generally, the cluster/component phase will be maintained by cluster controller, but if your operation will not update
	// StatefulSet/Deployment by Cluster controller and make pod to rebuilt, you need to maintain the cluster/component phase yourself.
	MaintainClusterPhaseBySelf bool

	// ProcessingReasonInClusterCondition indicates the reason of the condition that type is "OpsRequestProcessed" in Cluster.Status.Conditions and
	// is only valid when ToClusterPhase is not empty. it will indicate what operation the cluster is doing and
	// will be displayed of "kblic cluster list".
	ProcessingReasonInClusterCondition string

	OpsHandler OpsHandler
}

type OpsHandler 

type OpsHandler interface {
	// Action The action running time should be short. if it fails, it will be reconciled by the OpsRequest controller.
	// Do not patch OpsRequest status in this function with k8s client, just modify the status variable of ops.
	// The opsRequest controller will unify the patch it to the k8s apiServer.
	Action(reqCtx intctrlutil.RequestCtx, cli client.Client, opsResource *OpsResource) error

	// GetRealAffectedComponentMap returns a changed configuration componentName map by
	// compared current configuration with the last configuration.
	// we only changed the component status of cluster.status to the ToClusterPhase
	// of OpsBehaviour, which component name is in the returned componentName map.
	// Note: if the operation will not modify the Spec struct of the component workload,
	// GetRealAffectedComponentMap function should return nil unless phase management of cluster and components
	// is implemented at ReconcileAction function.
