So if I only run one Matrix/Synapse instance for my private group, does any of the matrix decentalized technology effect me? I would only have one instance, and my users will probably only be connected to my instance. Though if I’m understanding correctly, it sounds like if I subscribed to another instance, all of the chat communication on that entire instance is copied to my server as well? Does this include files? Sounds like it would use a lot of extra disk space.

I see why they recommend not using SQLite lol.

They released an update yesterday for TS3, allowing connection to TS5 servers I think, and breaking the Soundboard lol. TS5 is in closed-beta, right? I would think release would be within a year, but I’m not sure. Also, last I checked, I was reading mixed results on the platform, but I haven’t been able to use it myself.

So if I made my own Lemmy instance, and subscribed to !selfhosted, does that mean if Lemmy.world went down, the !selfhosted community is still up?

Do you know if this happens the other way around? A user chats with a different server and that chat is synced to my server. Can I use federation without allowing others to join mine outside my group? Because otherwise, it sounds like my server’s data will be copied to a different server.

So if lemmy.ml subscribed to lemmy.world, and world shut down with no warning, provided you aren’t a lemmy.world account, you can still access and make content on the world communities? Has this been tested?

Yeah, I’m trying to figure this out from a high availability standpoint. I guess the next question would be if all the servers are operating on the same out-of-sync server, probably not, as those servers aren’t connected together, they are just connected to the now-offline server. I wonder if the server comes back up if it propagates or trys to re-sync. Seems like we would have issues either way, and the best bet is finding an instance with good availability.

I was kind of hoping that if an instance subscribed to another instance’s community, then the originating instance can go down without effecting the community because another instance is now acting as the backup.

I’m also concerned if Lemmy as an application can support a large user base.

Thanks for the detailed reply!

I was thinking what if we switched to a fediverse Youtube replacement, such as PeerTube. However, I don’t think this would work. For one, because there are no ads, there’s no money being made, and creators would have to be backed by donations. Not sure how much money that would bring in.

Additionally, the difference between a “creator” on lemmy/subreddit (creating a community) vs a “creator” on youtube (uploads videos) is that I can be a creator without hosting an instance here. Looks like if I wanted to upload videos to PeerTube, I’d need to make my own instance or pay for one. Maybe if there was an option to select an instance just like here on lemmy, but videos take waaayy more disk space and processing to stream than text and a few images. Could be cool to host yourself though.

Thanks for hosting Lemmy.world! Does Lemmy use a database? Until the software gets horizontal scaling capability, could we use a central RDS so the load isn’t on the EC2 instance’s CPU? Then we can use load balancing between multiple instances that pull from the same DB? Obviously, the db instance is still a limiting factor.
