Re: Multitenent architecture - Mailing list pgsql-general

Hi Rob,

Our environment is medical clinical data, so each clinic as a tenant. Approximately 500+ tenants with 6TB data.

Thank you in advance.

Regards,

Vasu Madhineni

If the data size is more than 6TB, which approach better?

For few tenants, you can keep identical tables in several schemas and
set "search_path" to select a tenant.

With many tenants, you are better off with one table that holds the
data for all clients.  You can use Row Level Security to have each
tenant see only his or her data, and it might be a good idea to
use list partitioning on the tenant ID.

Yours,
