Instead of relying on 3rd party service, we could wrap them in bridge or expose through factory or facade

exp_factory_method.rb

def handle_action_created(action)
  if action.from.kind_of?(Source)
    $redis.lpush(
        "#{self.class.name}:#{self.id}",
        [action.from.node.id, action.from.node.neo_id].join(":")
    )
  end
end

# Perhaps we could do
def handle_action_created(action)
  if action.from.kind_of?(Source)
    RedisService.addJob(
      "#{self.class.name}:#{self.id}", 
      [action.from.node.id, action.from.node.neo_id])
    )
  end
end
