    FAQ

    Q: Why does the database storage size retrieved by using the SQL statement differ from the database storage usage displayed in the PolarDB console?

    A: The discrepancy arises because the SQL statement retrieves the logical size of the database, while the PolarDB console displays the physical storage usage measured at the file system level.
