Question for relay devs: I want to subscribe to all events that augment the events I'm currently displaying (zap receipts, reactions, and deletions). I'm considering making subscriptions with a long set of IDs in an "#e" filter. So my questions are:
1) How long can that get before relays complain the list is too long?
2) If I add a bunch of IDs to an existing subscription, does it start over, or does it remember that it already gave results for the previous ids? (I presume it would start over, which won't be useful for me)
3) If I then instead open new subscriptions every time I need to watch another batch of events, how many of those can I have before the relay gets mad at me? Because I'd be making new subscriptions every 10 seconds or so for a very long time without closing the old subscriptions.
4) Would it be more efficient for me to be watching all the events my user might see on screen all the time, or should I dump and restart subscriptions whenever the user changes to a different feed? That second method would be watching much fewer events, but would rewrite subscriptions frequently thus pulling redundant data.
I know I can look at the NIPs and program to that, but I thought I'd get to the best plan of attack faster by just asking.
