I was asked about how much (in percent) of a specific HANA database changes each day. This lacks of course a precise definition for "data change rate". So lets assume the HANA database consists of only 1 huge table. If each day x% of its rows are modified, i.e. all the values for these x% rows is changed, which metric of the HANA database could I query to determine x?
Or is there no such metric, and I have to resort to some kind of rule of thumb like: The database is y GB in size and it writes z GB of logs each day, therefore the change rate is z/y ?
