Row Generator stage

The Row Generator stage is a Development/Debug stage. It has no input links, and a single output link.

The Row Generator stage produces a set of mock data fitting the specified meta data. This is useful where you want to test your job but have no real data available to process. (See also the Column Generator stage which allows you to add extra columns to existing data sets, Column Generator stage.)

The meta data you specify on the output link determines the columns you are generating.

For decimal values the Row Generator stage uses dfloat. As a result, the generated values are subject to the approximate nature of floating point numbers. Not all of the values in the valid range of a floating point number are representable. The further a value is from zero, the greater the number of significant digits, the wider the gaps between representable values.
