    Cayenne doesn't currently support mapping indexes of any sort in the xml map file, although there is a task to add that functionality and it will be useful. For the moment you'll need to add any indexes you need directly.

    How you actually populate your column will depend on the application, whether it is threaded, whether you need the user to be able to define the value, etc.
