Every B2B client who asked us how we handle multi-tenancy also asked how we ensure their data is erased at the end of the contract. Using a shared database with RLS means you have to go through all DB backups, delete individual rows for that tenant, then re-generate the backup. That’s a non-starter, so we opted for having one DB per tenant which also makes sharding, scaling, balancing, and handling data-residency challenges easier.
