Overview

  • In Data Fusion, you can use Macros to introduce dynamic variables for plugin configurations so that you can specify the variable substitutions at runtime.

  • Macros are defined as variables wrapped inside of a **${ }**. Plugins that have macro enabled fields will contain a blue M icon.

  • A typical use case for macros is to allow for variable substitution when the pipeline is run, so instead of using hard coded paths, you could use dynamic paths. This way you’re able to specify which particular file you want to process when the pipeline is invoked. In addition to macros you'll use wildcards as well.
