Kettle Variables

Kettle variables provide a way to store small pieces of information dynamically in a narrower scope than environment variables. A Kettle variable is local to Kettle, and can be scoped down to the job or transformation in which it is set, or up to a related job. The Set Variable and Set Session Variables steps in a transformation allows you to specify the related job that you want to limit the scope to; for example, the parent job, grandparent job, or the root job.
