Max Number of Rooms

I need to host a very large number of Peer to Peer Jitsi Rooms ( let’s say a max of 1000 Rooms at any time) .
Let’s suppose that each couple of participant doesn’t need to use the CoTurn server and that Jitsi handles only the signaling.

In this scenario, what are the limitations or caveats that I should be aware of ?
Thank you very much for your amazing work.
