David asks: Assessed whether a db.t3.small RDS can actually serve 10,000 concurrent users

The session started with David establishing the target:

We need to be able to support 10,000 concurrent users, so we need to discuss whether our system can currently handle that. Don't just postulate; you actually need to go and launch agents to do the actual research on our AWS instance and all of that other stuff

When the agent suggested scaling up the RDS instance, David immediately pushed back on the cost premise:

we cant afford that as a base cost without the actual users (which could bring revenue). is that an increase in base cost?

He then questioned the diagnosis itself:

do a proper analysis of our db.t3.small and assess whether it seriously cant handle 10k users and can only handle a few hundred cause idk if im convinced

The follow-up question was the real focus:

what is the refactor plan to get us to 10k users at no increased (or negligible) cost? is that possible? and what env variable changes will we be making to make that happen?

This framing — validate first, then find the cheapest path — drove the scale investigation.
