How do Realtimes handle data?

Hi I have a question about how Realtimes handle data.

If you are connected to two rooms, do both of their room Realtimes handle the data, or is only one room sending/receiving data?

If the data is handled by both rooms, in this example. Is there a way to prevent this from happening?

In a scenario I am creating, I plan on allowing people to use various rooms at once, which makes me wary about the amount of traffic created.

Thank you

All RealtimeViews in a scene are associated with a single Realtime instance, and all data only flows through that Realtime instance. If you use two Realtime instances to connect to two different rooms, you’ll only synchronize the objects that belong to each room, it doesn’t immediately double the amount of bandwidth being used.
