When your data volume exceeds the purchased storage space, you can manually scale up the capacity through the PolarDB console.
Applicability
| Condition | Support |
|---|---|

Billing behavior when storage is exceeded
If your data volume exceeds the purchased storage space, the cluster continues to run normally. Data beyond the purchased capacity is billed on a pay-as-you-go basis.
