> Text based datasources like CSV, JSON and Text produces empty files for empty
> partitions. This introduces additional overhead while opening and reading
> such files back. In current implementation of OutputWriter, the output stream
> are created eagerly even no records are written to the stream. So, creation
> can be postponed up to the first write.
