Using separate databases or schemas per tenant comes with the following problems

* Managing schema migrations across every DB

* You cant query across the DB, want to know some cross tenant thing for ops? That's now a lot harder

* Connection pooling and resource usage can be harder to manage

Most systems I've worked on use a single DB with a `tenant_id` col on every relevant table, it's easy to have your query builder slap in the auth'd tenant I'd. This approach does come with issues like saving and restoring an individual tenants data

Like a lot of things in life, it's a trade off
