The storage capacity of PolarDB is automatically scaled in or out based on the amount of stored data. You do not need to manually specify the storage capacity. You are charged for only the used storage. If you need to store a large volume of data, we recommend that you purchase PolarDB storage plans. This reduces the storage costs. This topic describes how to view the deducted capacity of a storage plan.
