Expanding Disk Capacity

Function

Disk capacity is more likely to become the bottleneck of storage as workloads develop. When other resources are sufficient, disk capacity expansion can help you quickly break through the bottleneck without interrupting services or wasting CPU and memory resources.

Constraints

Disk capacity expansion can be performed only for cloud data warehouses using SSD or hybrid data warehouses. Only version 8.1.1.203 and later are supported.

In the pay-per-use + discount package mode, after the disk capacity is expanded, the capacity exceeding the package will be billed on a pay-per-use basis.

Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
new_size	Yes	Integer	Definition Available capacity of a single node after disk expansion, in GB. The value must be greater than the existing capacity of a single node and up to the maximum capacity of a single node supported by the cluster specifications. The value must be a multiple of the step supported by the cluster specifications. To query cluster flavors, see Querying Cluster Flavors. Constraints N/A Range N/A Default Value N/A
