For ejabberd and variations, the best approach is definitely not to duplicate the data.
ejabberd is extensible with hooks and you can build your own roster module quite easily with hooks. You can write a roster plugin that will either access your database directly or that query it through Rest API.

That's definitely the best approach.

You can also have a look in the code at mod_shared_roster. It is a good example showing that you can even write alternative logic to roster management.

You can mail me directly if you need some guidance.
