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.
Activities aren’t sent on every “connection” in the network in the current model. There isn’t indirect transmission nor polling so even though there’s a theoretical 50 mil connections in the scenario you gave, any one activity will already only be sent up to 10k times. That’s why instances require TLS and being internet accessible, so they can receive direct communication. I agree with you that there’s some difficult scaling issues with federation but your representation of it is inaccurate.
