The use case of the original mail "foreign keys are guaranteed to not be cross-tenant" seems like a good enough use case to me? The alternative to the discriminator column approach to seperating tenant data even when following referential integrety checks would be maintaining a copy of the table for each tenant, but this won't work as well due to (amongst others) syscache bloat, prepared statements being significantly less effective, and DDL operations now growing linearly with the amount of tenants in the system. Kind regards, Matthias van de Meent
