The storage capacity of PolarDB is automatically scaled out or in based on the amount of the stored data. You do not need to manually specify the storage capacity. You are charged for only the used storage. We recommend that you purchase PolarDB storage plans if you require a high storage capacity to store a large amount of data. This reduces the storage costs.

Notes

  • You can purchase only one storage plan of each type.
  • You are charged for the extra storage capacity that is not covered by the storage plan based on the pay-as-you-go billing method. Assume that you have three PolarDB clusters and each cluster requires 400 GB of storage. If you purchase a storage plan of 1,000 GB and these clusters share the storage plan, you are charged for the extra 200 GB of storage based on the pay-as-you-go billing method. For more information,see Manage storage plans.
