    |---------------------------------------|--------------------------------------|
-   | `spec.clusterDefinitionRef`           | It specifies the name of the ClusterDefinition for creating a specific type of cluster.  |
-   | `spec.clusterVersionRef`              | It is the name of the cluster version CRD that defines the cluster version.  |
    | `spec.terminationPolicy`              | It is the policy of cluster termination. The default value is `Delete`. Valid values are `DoNotTerminate`, `Delete`, `WipeOut`. For the detailed definition, you can refer to [Termination Policy](./delete-mysql-cluster.md#termination-policy). |
    | `spec.affinity`                       | It defines a set of node affinity scheduling rules for the cluster's Pods. This field helps control the placement of Pods on nodes within the cluster.  |
    | `spec.affinity.podAntiAffinity`       | It specifies the anti-affinity level of Pods within a component. It determines how pods should spread across nodes to improve availability and performance. |
