Transformation script workflow

At a high level, creating a transformation script and running it against your project data set involves the following steps:

  1. Create a transformation script using transforms and optionally custom transform functions.
  2. Use preview to debug your transformation and view its effects on your data.
  3. Save the transformation to your transformation script.
  4. Edit your transformation script by rearranging, modifying, and deleting individual transformations.
  5. Run your script against the project data set. This updates your copy of the project data set (it is a sample of the source Hive table), and makes it available in Discover area of Studio.
