Data Resource - Generator

About

A data resource generator is a content data resource that generates data.

Syntax

A generator is a yaml file terminated by the suffix –datagen.yml that follows the data definition file syntax.

It adds:

the maxRecordCount attribute (maximum number of record generated)
and the DataGenerator node where the column generator properties are set.

MaxRecordCount: 30
Columns:
  - name: columnName
    comment: A column with a sequence integer generator and its properties
    DataGenerator: # the data generator node definition for a column
      type: sequence
      start: 3
      step: 2
      maxTick: 5
  - name: columnName2
    ........

See the column generator page to see all type of generations that you can choose for a column.
