Deleting Nodes

Scenarios

You can add or delete nodes for a pay-per-use or yearly/monthly instance to release resources.

Precautions

• Deleted nodes cannot be recovered. Exercise caution when performing this operation.
• When deleting a node, contact customer service to configure a waiting period (1s to 5 minutes) for the node to restart, so that the system can disconnect all persistent connections on the node during this waiting period. The waiting period takes effect on all nodes.
• If a dual-active relationship has been created for two instances, do not change their specifications or add or delete nodes to or from them.
• If you enable operation protection, two-factor authentication is required for sensitive operations to secure your account and cloud products. For details about how to enable operation protection, see Identity and Access Management User Guide.
