The first column indicates a project in which the ancestor table is located, the second column indicates a project in which the descendant table is located, and the third column indicates the number of lineage relationships between the two projects.
Top Projects by Table Storage The top 10 projects that occupy the most storage space within the organization.
Top Tables by Occupied Storage The top 10 data tables that occupy the most storage space within the organization. You can click a table name to go to the details page of the table.
Note The logical storage space occupied by projects and tables is collected in a T+1 manner. The numbers next to the project and table names indicate the sizes of the occupied logical storage space. Besides the table storage volume, the project storage volume includes 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. The table storage volume is charged based on the logical storage rather than the physical storage.
