Hmm, I'm beginning to see the issue here with one way Federation from Threads.
@ai6yr Are you concerned about some sort of volume? Or is it that you can only subscribe and not reply? Or something else?
@rob @ai6yr to me, the mechanics of the comms is one of the more realistic potential problems with threads. Masto is apparently a somewhat inefficient architecture, adding significant volume to a small instance could be problematic

@pixelpusher220 what is small? and where would the significant volume come from?

I have my own hosted instance, so that's why I am asking.

@ai6yr

@rob @pixelpusher220 I've got a small instance, but with a lot people/bots that are followed... if you had a *lot* of people from Threads follow it would (currently) create a huge outgoing queue backlog when there is high post volume, I believe... i.e. a single person followed by 5000 people results in 5000 outgoing requests to servers (posting that thing to all 5000 people following you).

@ai6yr @rob or 25,000 'reports' of a post or account.

just the influx of a node with 100 million people being processed by nodes of of the size of 10. Any interaction has the potential to bring the small node to it's knees conceptually.

@ai6yr @pixelpusher220 That’s so weird. You’d think that if 4,999 were on Threads and 1 was on a different server, that’d be 2 posts. One to Threads, which would then route to the single addresses and one to the other sever. But you’re saying that’s not how it works.

I guess servers don’t route messages to accounts. Everything happens at the account level.

Is that right?

@rob @pixelpusher220 UPDATE: looks like Mastodon accepts shared inboxes, and *does* distribute internally. So it's just queues to every SERVER (vs. every account). So perhaps this is not as inefficient and I had been thinking. https://seb.jambor.dev/posts/understanding-activitypub/
Understanding ActivityPub - Part 1: Protocol Fundamentals

I explain how I'm using ActivityPub.Academy to explore ActivityPub.

@ai6yr @pixelpusher220 I think where you might get crushed is if you had a viral post that tens of thousands of people responded to with media attachments. Now there I could see a server wilting under the bright glare of a much larger server.
