Elixir is well suited to highly concurrent systems and work like this. I'm big on the whole Elixir ecosystem though so I haven't explored other options.

I don't see why there would be anything stopping Go from being similarly capable as it also has a good reputation for concurrency and what I hear does preemptive scheduling.

Java can probably do anything except be fun and lightweight so assuming you want to figure out the hoops to jump through. I assume it could..

Elixir can do it with the ergonomics and expressiveness of Python/Ruby. If you enjoy that level of abstraction I recommend it.

Do you have any pointer, book preferably, in starting an exploratory Elixir project? I don't have any objective apart from giving the ecosystem a taste

If you really want a book pick one from here [0]. First one is good.

Personally I think just following the official guide [1] will give you all you need to get a taste of the language and the platform and decide if you like it or not.

If you were talking about websockets in particular I guess realistically most people use Phoenix Channels [2] that give you websockets in ten lines of code.

I can highly recommend Elixir in Action, 2nd ed.

This talk by the same author is also a good introduction in video format: https://www.youtube.com/watch?v=JvBT4XBdoUE

Java is slowly absorbing the ideas from other systems and is much more fun than it was.

Also versatile.
