Why do you want a central controlling authority in the first place, whether or not it is geographically sharded? Why is there any need for any sort of database, 4D or otherwise? Simply have the drones talk to each other and negotiate how to avoid each other directly, like small plane pilots following visual flight rules. No need for a database. No need for any authority.
