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.)
Is your logic faulty?
Yes, there are 50M total connections between 10k nodes, but when one server sees one comment/updootmwhatever, then that server "only" needs to send it to the 10k peers.
Those peers do not need to pass it on to all other peers; that would mean 50M messages total, but again, not from each peer.
