Wouldn’t that mean you’re holding lots of non reusable connections?

I have recently been using row level security with a transaction middleware where I set the tenant ID.

Nice article regarding it - https://aws.amazon.com/blogs/database/multi-tenant-data-isol...

We have about 6 physical DB servers, each client has their own db/schema on one of those boxes. Several thousand clients each with 10s of users per client. It brings in $15m ARR.

So, it works.

We're wanting to move off that architecture to something more future proof, but it's not our biggest pain point at this point in time.
