so my boss is losing his mind because i set up the new db to spin up a new table every time someone signs up. like `user_10293_tx` and `user_10293_profile`. he says it ruin query planning but like... isn't this just microservices for data? zero chance of sql injection leaking other users data if they are in completely separate tables. plus it scales horizontally if we just put different tables on different physical drives. feels like traditional dbs are just too rigid. why are people so obsessed with 3nf when cloud hosting costs are so high anyway. dynamic schemas are the future guys
