> ... prevent over-fetching

This is handled server side. Subscriptions are more like 'live queries'. The server sends the data to the client only when the result set for the given 'live-query' changes.

It sounds like the server has to keep track of all active live-queries. Does it need to re-fetch all of them on every update?
