we have a big DB - ~150gb. Our study has 15m records, so this isnt totally surprising. however, exp.object is enormous, much bigger than i'd expect. i'd like to figure out what exactly is causing all this. does anyone have advise on how to best approximate what's being stored here? we have almost no lists, but i would expect audit trail to store records here.

no need to provide the full SQL - a description would probably be good enough to get us going.

thanks.
