O wait, the whole federation allows federation of just users and not communities?
So all this time I have been looking at posts just on the main instance and not posts across all instances?
fugggggggg so now I have to go search for communities of same name on all other instances as well and subscribe to them? ok, fine. How do I do this? there should really be something that automates this process
No, communities are the main federated item in lemmy.
For example, !calckey@lemmy.blahaj.zone is also viewable from here: https://lemmy.ml/c/calckey@lemmy.blahaj.zone
Do instances "subscribe" to get the communities of other instances? Or how does it work the "all" filter?
Instances don't subscribe. People follow federated communities. So you can type !gaming@beehaw.org into the search bar here, and subscribe to it.
Yeah, I understand that, it's why I used subscribe in quotes since I didn't know to phrase it better.
My question is, how an instance knows about the communities of other instances so they appear when changing from "local" to "all"?
Is it only until a user searches for them in that instance? Before that both instances are unknown to each other?
Or is there a config so one instance tries to always be updated of other instances?
Federation is based on a push methodology, that happens after a subscribe. The flow is that I subscribe to a federated community, and that community's server now knows my activitypub id, and can push community posts and comments to my servers inbox. The connection happens after that first subscribe.
