I have objects which represent users, the key to each object is their email address encoded as a String. Having the email address as the key works well so i'd like to keep it that way rather than having an auto incrementing Long key.
However, for reasons I wont go into here, I need a way of identifying user objects via a meaningless number rather than an personal email address. I assumed the datastore may hold a unique auto incrementing number for each object regardless of the key type used and if so I was wondering how one may access it?
