> In a scenario where there are many files which all share the same key/value
> types, e.g., when dealing with measured data from sensors, it should be
> possible to join multiple files. That means, there should be a reader which
> can be supplied with one or more directories containing files, and it should
> be possible to read the records of all files in order.
