> Pig currently allows users some control over InputFormat via the Slicer and
> Slice interfaces. It does not allow any control over OutputFormat and
> RecordWriter interfaces. It just allows the user to implement a storage
> function that controls how the data is serialized. For hadoop tables, we
> will need to allow custom OutputFormats that prepare output information and
> objects needed by a Table store function.
