You can manually release pay-as-you-go clusters based on your business requirements. The pay-as-you-go clusters are charged on an hourly basis. This topic describes how to manually release PolarDB for MySQL clusters.

Considerations

  • You cannot manually release subscription clusters. Subscription clusters are automatically released when they expire.
  • You can manually release the cluster whose Status is only Running.
  • You can use this feature to release clusters. If this feature is used, all the nodes of the clusters are released. For more information about how to release a single read-only node, see Add or remove read-only nodes.

Procedure

  1. Log on to the PolarDB console.
  2. In the upper-left corner of the console, select the region where the cluster resides.
  3. On the Clusters page, find the cluster that you want to release and choose More > Release in the Actions column.

  4. In the Release Cluster dialog box, select a backup retention policy and click OK.
    Select a backup retention policy and release the cluster
    Retain backups Description
    Retain All Backups Permanently Retains all the backups for a cluster when you delete the cluster.
    Retain Last Automatic Backup Permanently Retains the last backup for a cluster when you delete the cluster.
    Delete All Backups Immediately Deletes all the backups for a cluster when you delete the cluster.
    Warning If you select this policy, the deleted clusters cannot be restored.
    Note
    • If you select the Retain All Backups Permanently or Retain Last Automatic Backup Permanently policy, the system runs an automatic backup task to retain all the data about a cluster when you delete the PolarDB cluster.
    • After you delete a cluster, level-1 backups are automatically transferred to level-2 backups. You can go to the Cluster Recycle page to view retained backups. For more information, see Cluster recycle bin.
