The Erlang Runtime System
Erlang/OTP doesn't handle leader election, and by itself is bad at handling netsplits.
There is https://github.com/rabbitmq/ra which is a Raft implementation in Erlang that is Jepsen-tested. You could use it to build "etcd in Erlang", or https://github.com/rabbitmq/khepri which is built on top of Ra.

Khepri is a tree-like replicated on-disk database library for Erlang and Elixir
https://rabbitmq.github.io/khepri/ has a bit more information on why you might want to use this, from what I can understand. It's a bit over my head. I guess its sort of simpler to manage a bunch of data on a disk vs a regular db (when not considering that just a bunch of data on disk), mostly around network issues?

New scalable, fault-tolerant, and efficient open-source MQTT broker
Shameless plug since i'm a contributor but VerneMQ [1] is a pretty programmable one. You have options from using webhooks to writting your plugins in Lua or Erlang/Elixir.

All right, which one of you did this?
I do know a real world use for Erlang (it also surprised me when i investigated about it), but two of the biggest mqtt brokers are coded in erlang: emqx, vernemq

Mosquitto: An open-source MQTT broker
The VerneMQ bugtracker scares me. Especially this one: https://github.com/vernemq/vernemq/issues/1663. I'm running one instance but I'm on the lookout for an alternative that can more reliably save messages if a subscription client goes down.

It took almost a full day, but I finally got a decent homelab diagram :D Feedback is most welcome!
