Number of concurrent client subscriptions
I am considering using Convex for a side project, an app to handle everything related to a TCG tournament. I'm particularly interested in the real-time aspect of Convex.
I expect a maximum of a few hundred concurrent users if this were to be used for an actual tournament, maybe a couple thousands if multiple tournaments are happening at the same time.
Most users (players) would only be receiving updates, while a few (referees and tournament organizers) might actually change the state of the tournament.
As I wouldn't earn money for this, at least not at first, I am only considering the free tier or self-hosted for now. I see the following on the Pricing page, but I don't know what that means: is it a measure of how many subscriptions can be handled at any given time, or is it a more abstract performance indicator?
Thank you in advance for your help!
