I would like to know if anyone has done any testing on how much
additional redo is generated if supplemental log groups are created on
tables. I know that it will depend on the number of columns in a log
group, column size, data type, etc., but I just want to get an idea
about generally how much additional information (in terms of %age) is
generated for DML statements.


Any feedback will be appreciated.


Thank you
