Step into the world of Disney Streaming as we unveil the creation of our Foundational Medallion, a cornerstone in our architecture that redefines how we manage data at scale. In this session, we'll explore how we tackled the multi-faceted challenges of building a consistent, self-service surrogate key architecture — a foundational dataset for every ingested stream powering Disney Streaming's data-driven decisions. Learn how we streamlined our architecture and unlocked new efficiencies by leveraging cutting-edge Databricks features such as liquid clustering, Photon with dynamic file pruning, Delta's identity column, Unity Catalog and more — transforming our implementation into a simpler, more scalable solution. Join us on this thrilling journey as we navigate the twists and turns of designing and implementing a new Medallion at scale — the very heartbeat of our streaming business!
