Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Disk works too, but if you're multi-node this means you now have a distributed database embedded in your system, which may or may not be your goal :)
RabbitMQ does this, they developed a library for "persistent, fault-tolerant and replicated state machines" based on Raft: https://github.com/rabbitmq/ra.

Ask HN: Good examples of fault-tolerant Erlang code?
Making cluster fault tolerant is an art on its own in Erlang ;)
Riak Core is extremely cool, but Riak is dead by now. It was a child of the times when NoSQL was cool. Still, basho code is interesting to read. (https://github.com/basho/riak_core)
Self-ads: we've tried to remove Mnesia from our project, HN post incoming, once the library is prettified and tested hard (https://github.com/esl/cets).
