PolarDB：Release a cluster

Precautions

• You cannot manually release subscription clusters.

  Note

  For information about how to manage a subscription or pay-as-you-go cluster after the cluster expires or after the payment for the cluster becomes overdue, see Cluster expiration and overdue payments.

• You can manually release a cluster only when the cluster Instance Running Usage is in the Running state.

  Note

  To release a serverless cluster whose Instance Running Usage value is Stopped, you must first start the cluster and change the Instance Running Usage value of the cluster to Running. For information about how to manually start a serverless cluster, see Manually start a cluster.

• This feature is designed to release the entire cluster, including all nodes in the cluster. For information about how to release a single read-only node, see Add or remove read-only nodes.
