So, I’ve tried using GitHub - rabbitmq/ra: A Multi-Raft implementation for Erlang and Elixir that strives to be efficient and make it easier to use multiple Raft clusters in a single system. · GitHub
I’ve found some minor quirks (like inconsistencies when using ra:start() vs application:ensure_all_started(ra), or ra:overview() blowing up if ra is not started), but overall the main issue I can see with my main requirement of simplicity of use is that ra needs specific handing of cluster initialization & changes. Just like mnesia, in some way.
You can’t simply add / remove a node automatically, you need to specifically manage its addition to an existing cluster, and you can only do so one node at a time. You can’t simply “merge” nodes of different clusters for instance, afaik. This requires some level of sys-op tooling. It’s not an issue per se’ of course, it’s just that I’m looking for something simple to use and deploy.
Also, I’ve tried reading about how to manage conflict resolution handling in case of net-splits, but I couldn’t find a specific place where to look at. Admittedly I haven’t spent a lot of time searching for this one in particular, so I may have just missed it.
My little experiment ram handles all of these things btw, but it probably has other issues that are instead perfectly handled by ra.
