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!
