I am troubleshooting an issue I suspect is related to database size. After enabling Attachments on a feature class, there is a resultant table called FeatureClassName_attach, and that table contains a field called DATA_SIZE. What unit is this field in? No matter what unit I guess, the result seems crazy, and I can't find a definitive answer in the documentation.
