After cluster deletion protection is enabled, the cluster cannot be deleted through the console or an API. To delete the cluster, you need to manually disable the deletion protection feature first. It is recommended to keep this feature enabled for key businesses.

Cluster deletion protection does not apply to system-level deletion. For example, pay-as-you-go clusters are isolated and subsequently released due to overdue payment, and yearly/monthly subscription clusters are isolated and released after expiration.

There are three entries to enable cluster deletion protection.
