How does federation work with the "subreddit" model? (lemmy.blahaj.zone)

Hi, I'm new here, so sorry if this has been asked before.

I understand that Lemmy is supposed to be like a decentralised Reddit, but I've got a question about this; on Reddit, there is only one server, with subreddits on it, so there is only one r/Music, only one r/AskReddit, etc.

However, on Lemmy there are many servers; would this lead to a situation where many servers have repeats of the same popular communities or does this not happen in practice? Is there a good way for me to find communities across all federated instances? Thanks :)

Communities are per server, as I understand it. Two servers might host communities that have the same name, but they are different distinct communities. There is no global namespace.

Imagine two servers, each focused on a different city: !news@chicago.il.us.gov and !news@losangeles.ca.us.gov would be different, despite having the same name

Thanks for elaborating. My comment wasn't very clear.

Eh, your comment was pretty clear as-is. Hope I helped, though. 😅 This fediverse stuff is sometimes tangly to explain & understand

Indeed! Your example illustrates the idea very well though :D
