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.
(Also- as federation has been completely broken on this particular server for me- there is a good chance I will not be able to see, or reply to anything posted below… That is, also assuming this even posts correctly to this server.)
I would say no to this immediately In its current form. Because those big expensive hub servers are going to become gatekeeping tech companies like Facebook and Reddit (well not specifically them most likely, but someone like them). You’re handing the keys to our new castle straight back to the corporate overlords.
Perhaps something can be done using message routing similar to this that is separate from federation; or maybe it’s up to large instances to host CDNs.
What is being proposed here is turning the fediverse into a Reddit CDN, and I’m not on board for that.
