Scenarios

This section describes how to scale up the storage space of a DB instance to suit your service requirements.

  • You can scale up a DB instance a maximum of eight times.
  • You cannot scale up a DB instance in Creating, Changing instance class, Adding node, or Deleting node status.
  • Storage space can only be scaled up. It cannot be scaled down.
  • You cannot scale up the storage space of a config for the cluster instances.
  • During the scale-up process, the DB instance will not restart, and your services will not be interrupted.
