How "heavy" is self-hosting matrix really? (programming.dev)

Hi. I'm kinda of a noob in the world of self-hosting and matrix, for that matter. But I was wondering how heavy is it to host a matrix server?

My understanding how matrix works is each participating server in the room stores the full history and then later some sort of merging happens or something like that.

How is that sustainable? Say in 5 years matrix becomes mainstream and 5 people join my server and each also join 3 different 10k+ people rooms with long histories. So now what I have to account for that or people have to be careful of joining larger rooms when they sign up in a smaller-ish server?

Or do I not understand how Matrix works? Thanks.

You could even argue it with the data structures and the protocol itself: Modelling chat rooms as graphs ("directed acyclic graphs"), which need to be eventually consistent from beginning to end is plain madness for big and long-living public spaces. This blog post is a good collection of some of the major problems coming from that: Why not Matrix? - telegra.ph

I knew of some of these issues with the protocol, but this article definitely gives an impression that Matrix was built as a "cool protocol" first, with messaging applied on top as an afterthought.

Welp. This comment has completely killed all my enthusiasm for matrix 😅 I had no idea it was such a horrible mess under the hood...

I'm trying to move some communities off Discord to something self hosted but I don't know enough about SMPP to know if it would do the job.
