> If you are planning on using persisted connections, the large number of DB approach is going to have a significant disadvantage. You cannot pool connections between databases. So if you have 2000 databases, you are going to need a minimum of 2000 connections to service those database (assuming you want to keep at least one active connection open per client at a time).
That isn't exactly true. You could run multiple poolers.
