This course introduces you to the concept of using PySpark to merge data in Lakehouses, helping you understand how Fabric handles large-scale data processing with flexibility and performance in mind. Manuel walks you through a hands-on example of writing a PySpark merge statement in Fabric, showing you where to write, how to test, and how to run the code directly in the platform. Whether you’re new to PySpark or exploring how Fabric supports advanced data workflows, this session provides a practical, focused introduction to a powerful technique.
