The storage capacity of PolarDB is automatically scaled in or out based on the amount of data. You do not need to manually specify the storage capacity. You are charged for only the storage space that is occupied by the actual amount of data. We recommend that you use PolarDB storage plans if you need to store a large amount of data. This reduces the storage costs. This topic describes how to renew or upgrade a storage plan.
