Shared Storefile Size is the Storefile size shared between snapshots and active tables.
       Mob Storefile Size is the Mob Storefile size shared between snapshots and active tables.
       Archived Storefile Size is the Storefile size in Archive.
       The format of Archived Storefile Size is NNN(MMM). NNN is the total Storefile
       size in Archive, MMM is the total Storefile size in Archive that is specific
       to the snapshot (not shared with other snapshots and tables)
