[Architecture] Hub-Spoke model for federation? · Issue #3245 · LemmyNet/lemmy

Question One of the biggest issues I am currently seeing with Lemmy, is federation. Either... Federation between instances having issues. Federation is backed up. Federation / Syncing is not scalin...

https://github.com/LemmyNet/lemmy/issues/3245

I posted far more details on the issue then I am putting here-

But, just to bring some math in- with the current full-mesh federation model, assuming 10,000 instances-

That will require nearly 50 million connections.

Each comment. Each vote. Each post, will have to be sent 50 million seperate times.

In the purposed hub-spoke model, We can reduce that by over 99%, so that each post/vote/comment/etc, only has to be sent 10,000 times (plus n*(n-1)/2 times, where n = number of hub servers).

The current full mesh architecture will not scale. I predict, exponential growth will continue to occur.

Let’s work on a solution to this problem together.

    Nice but it kinda breaks the point of federation - who’s running the hubs? If it’s a company, then nice, we’re back to appeasing our corporate overlord. I

    If it’s a secondary federated system, nice now you’re just needlessly complicating things, as anyone could create a hub - you could end up with a lot of single spoked hubs.

      Load wise, having the hub separated to own server would make scaling easier. So even one hub and one instance solution for large instances could work. For personal instances this solution would be nice, because they could share one hub, and federate through that.

      No one is suggesting here to have any company host the hub.
