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.)
A really important concern, we will need to adress, but i’m not sure if the proposed hub-servers really are the solution, they kind of kill many benefits of the decentralized architecture of federation, but definitely a good idea
