def join(*args)
  Familia.join(args.map { |field| send(field) })
end

#rediskey(suffix = nil, ignored = nil) ⇒ Object

suffix is the value to be used at the end of the redis key (e.g. ‘customer:customer_id:scores` would have `scores` as the suffix and `customer_id` would have been the identifier in that case).

identifier is the value that distinguishes this object from others. Whether this is a Horreum or RedisType object, the value is taken from the ‘identifier` method).
