    Top Tables by Occupied Storage The top MaxCompute tables that occupy the most storage space within the current Alibaba Cloud account. You can click a table name to go to the details page of the table.
    Note The logical storage space that is occupied by projects and tables is calculated in a T+1 manner. The numbers next to the project and table names indicate the sizes of the occupied logical storage space. The project storage volume includes not only the table storage volume but also the storage volumes of resources, data in the recycle bin, and other system files. Therefore, the project storage volume is larger than the table storage volume.

    You are charged for the logical storage volume instead of the physical storage volume of a table.
