Elixir! I've got such a mixed bag of feelings for that language.

  It's elegant but it's build-times are pretty terrible.

  It has the RPC stuff built-in but I've never seen anyone use it in production and instead folks are doing redis or 
 something else traditional.

  It has elegant process management but it's cloaked in magic (that you have to carefully learn).

To your question - this weekend I'm learning kafka's client protocol (and maybe amqp protocol?) and try to write a transparent proxy of sorts.
