It refers to the coordination and management of tasks in data transformation through well-defined dependencies between them. There are many business reasons for orchestration, but consider the following simple example. You need a report delivered daily and you need to process the data for that report each day. This requires orchestration.

In this chapter, we are going to look at some of the most common tools and techniques used for data pipeline orchestration. Two of them, Airflow and Argo, are open source, whereas Databricks workflows and Azure Data Factory are proprietary software.
