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 only for the used storage. If you need to store a large amount of data, we recommend that you use PolarDB storage plans. This reduces the storage costs. This topic describes how to renew or upgrade a storage plan.
