# This is a basic implementation of the Notification service using Amazon SNS.
# The expected usage is as follows :
#   notification_service = DispatchRider::NotificationServices::AwsSns.new
#   notification_service.publish(:to => [:foo, :oof], :message => {:subject => "bar", :body => "baz"})

  module NotificationServices

      # not really happy with this, but the notification service registrar system is way too rigid to do this cleaner
      # since you only can have one notifier for the whole service, but you need to create a new one for each region

        arn = fetch(name)
        # in v1, the Topic object was fetched from API, in v3 it's basically just an arn wrapper
