    Description

      there are some confusion here-and-there....and most probably because the following cases are both valid:

      • the full row size of a table is x bytes
      • the actually used field sum from a table is x bytes

      there is another axis:

      • online: including object headers/etc (string value "asd": >100 bytes)
      • offline: just raw data (4 bytes)
