PolarDB:Pay-as-you-go + storage plans

Last Updated:Nov 09, 2023

When storage plans are used for the pay-as-you-go storage of your cluster, the system deducts the storage plans first for the consumed storage capacity. After your storage plans are exhausted, you are charged for the excess storage on a pay-as-you-go basis. This topic describes the billing rules for this combination.

Deduction rules for storage plans

Note

Storage plans can be used only on clusters that use the pay-as-you-go billing method for storage, and cannot be used on clusters that use the subscription billing method for storage.

Storage plans can be used to deduct consumed storage capacity based on specific ratios. The following table lists the ratios.

For example, for a PSL4 cluster in a region of the Chinese mainland with hot standby storage cluster enabled, a 50-GB storage plan can be used to deduct a storage capacity of 76.92 GB (1/0.65 × 50). Excess storage usage over 76.92 GB is charged on a pay-as-you-go basis.

The following table lists the actual amount of storage capacity that can be deducted from storage plans.
