Generate Big Data

Description

This activity expands the dataset by generating additional rows based on a user-defined expansion factor. The widening process utilizes specified key columns containing unique sequential values to maintain consistency. If the number of data rows is “a” and the expansion factor is “b”, then the total number of generated rows will be a × b.

Input
