Storing & Fetching Tenants From A Database

[conradakunga]

I have a use case where I would like to store the tenants, or at least the tenant ID, in a database. In other words, the tenants are not known in advance and essentially can self-provision.

My first idea was to have a separate database that would be used to register the tenants and then fetch and pass the IDs to this call:

1. Is this way of achieving this the best way or is there a better way?
2. Is it possible / recommended to use the same database for the tenants?
