The storage is used to store cluster data files, index files, log files, and temporary files. Log files include online logs and archived logs. This topic describes the billing and pricing for storage resources.

Note After you purchase a PolarDB cluster, the system automatically creates the files that are required for regular database operations. These files include the preceding files and consume some storage.

Pay-as-you-go

A serverless architecture is used for storage. Therefore, you do not need to specify the storage capacity when you purchase clusters. The storage capacity is automatically increased when the amount of data increases. You are charged for only the storage that you use. On the Overview page of the clusters, you can view Database Storage Usage. For more information, see View the database storage usage.

  • Mainland China: USD 0.00077/GB/hour
  • China (Hong Kong) and regions outside China: USD 0.00085/GB/hour
Note Each cluster specification has a corresponding maximum storage capacity. If the capacity usage reaches 90%, the system sends text messages and emails to you on a daily basis. If you need to increase the maximum storage capacity, upgrade your cluster specifications. For more information, see Change cluster configurations.

Storage plans

If you need to store a large amount of data, such as 1,000 GB or more, storage plans are more cost-effective than the pay-as-you-go billing method. Higher discounts are offered for the storage plans that provide larger storage capacities. For more information, see Purchase a storage plan.
