In the world of modern data engineering, reusability, scalability, and maintainability are not just nice to have; they are essential. As more teams embrace the Medallion Architecture within Microsoft Fabric, the need for modular, reusable logic becomes even more critical. That’s where User Defined Functions (UDFs) come into play.

In this session, we’ll explore how to supercharge your Fabric pipelines by introducing UDFs at each stage: from Bronze (raw ingestion) to Silver (data enrichment) to Gold (analytics-ready outputs). You’ll learn how to enforce data quality early, enrich data consistently, and create advanced metrics with ease. Whether you're building dashboards or exposing insights through APIs, these UDF patterns will help you streamline your logic and reduce code duplication across your lakehouse.
