View Source Infinitomata (Finitomata v0.22.0)
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)
endSummary
