The sibling of Finitomata, but runs transparently in the cluster.

If you want to use a stateful consistent hash ring like libring, implement the behaviour Finitomata.ClusterInfo wrapping calls to it and invoke Finitomata.ClusterInfo.init(Impl) before using Infinitomata.start_fsm/4.

The example of such an implementation for libring (assuming the named ring @ring has been started in the supervision tree) follows.

defmodule MyApp.ClusterInfo do
  @moduledoc false
  @behaviour Finitomata.ClusterInfo

  @impl Finitomata.ClusterInfo
  def nodes, do: HashRing.nodes(@ring)

  @impl Finitomata.ClusterInfo
  def whois(id), do: HashRing.key_to_node(@ring, id) 
end
