AWS Glue Studio now provides data previews during visual job authoring

AWS Glue Studio now allows you to preview your data at each step of the visual job authoring process. AWS Glue Studio automatically samples your data, then runs each transform in your job so you can test and debug your transformations without having to save or run the job. Data previews are available for each source, target, and transform node in the visual editor, so you can verify the results step by step.
