TorpoGias has built-in support for horizontal data part, or what's in a sharding. You can just set up different database sessions, one for each shard and reduce the new models on one session or the other. That works with relational databases as well. And whenever you perform a query on this or that model, or whatever, any extension, the admin or whatever you're using performs a query on that model. It means no data has to perform that query on that database shard.
