defmodule Actors.Registry.LoadBalance.Strategies.Random do
@moduledoc """
`Random` implements the `Actors.Registry.LoadBalance.Strategy` behavior
by searching the actors randomly, that is,
if you have registered the same actor in N nodes and try to invoke it,
the Registry can, if configured,
use the random strategy to locate one of them in any of the nodes in a random way,
as the name suggests.
