NULL storage size

    Description

      Hello

      Is it possible to add some documentation about how much a NULL value takes in terms of storage?

      I couldn't find any reference in these pages:

      https://mariadb.com/kb/en/null-values/

      https://mariadb.com/kb/en/data-type-storage-requirements/

      I understand NULL is not an empty string nor a 0.

      A 0 in a BIGINT field would take 8 bytes as far as I understand.
      How much is a NULL in a BIGINT? (just an example question)

      And does it depend on the ROW_FORMAT?

      (assuming InnoDB Barracuda anyway)

      Thank you very much!
