    Note

    The Top Projects by Table Storage and Top Tables by Occupied Storage sections display the logical storage space that is occupied by MaxCompute projects and the logical storage space that is occupied by MaxCompute tables. The statistics are generated and collected in offline mode. The logical storage space displayed for each project includes the logical storage space occupied by tables, resources, recycle bins, and files of other systems. As a result, the logical storage space displayed for each project is greater than the logical storage space occupied by tables in the project.

    You are charged for the logical storage space of tables but not the physical storage space of tables.

    Most Frequently Used Tables

    The tables that are most frequently accessed. The statistics are generated based on the number of views of the details page of each table. The statistics on Most Frequently Used Tables are collected in real time.
