Transform units

Learn how to transform data source outputs for use in pipelines.

A Transform unit is used to modify the output of a data source by creating a new parameter structure and mapping existing attributes to the new parameters. It is often used to prepare output for a Merge unit.

To use a Transform unit, you first create a new property, which can be an object, an array or a literal, that matches the structure of the data source. You then add attributes to the structure and then modify the value of each attribute using references, Axel-f functions and operators.
