For clusters whose storage is billed by space (subscription), you can expand the storage capacity by manually scaling up. This topic describes the procedure for manually scaling up storage capacity.
Background information
If your business data volume exceeds the purchased storage space, the normal use of the cluster is not affected. Data that exceeds the purchased storage capacity is billed by capacity (pay-as-you-go), following the capacity-based pricing.
Scope of application
-
Only clusters whose storage is billed by space (subscription) support manual scale-up. Storage that is billed by capacity (pay-as-you-go) uses the Serverless mode, which does not require you to select a capacity at purchase and automatically scales up online as data grows.
Procedure
-
Log in to the PolarDB console，In the navigation pane on the left, click Clusters. Select the Region where the cluster is deployed, and then click the cluster ID to go to the cluster details page。

On the Basic Information page, in the Distributed Storage area, click Manually Scale Up.
