saas - Multi-tenant Data Models -

-

i've been reading on multi-tenant design pattern , had few questions data model options use case. want build saas allows users add, update, , read large datasets. i'm targeting niche industry don't expect many users, maybe 15 20.

however, each tenant require unique schema anywhere between 5 tables 10 tables depending on specific needs. records in hundreds of thousands.

the article linked above talks 3 different data models can used multi-tenant, , i'm wondering pros , cons of each use case.

i assume need database-per-tenant since schemas need quite different each other, costly. possible on shared database-single since don't need worry more 20ish tenants?
