The cluster lock feature protects pay-as-you-go clusters from accidental manual release. Enable it on any cluster you want to protect.
Prerequisites
Before you begin, ensure that you have:
A PolarDB cluster with the pay-as-you-go billing method
Limitations
Cluster lock blocks manual release only. It does not prevent the system from automatically releasing a cluster in the following situations:
Your account has an overdue payment for more than 8 days.
The cluster does not comply with the applicable security compliance policies.
If you plan to switch a cluster's billing method from pay-as-you-go to subscription, disable cluster lock first. Clusters with cluster lock enabled cannot be changed to subscription.

From the Clusters page: Find the cluster, and then choose More > Add Cluster Lock in the Actions column.
From the Overview page: Click the cluster, and then click Enable next to Cluster Lock.

To enable or disable cluster lock programmatically, use the ModifyDBClusterDeletion API operation.
