Daft and Unity Catalog: A Multimodal/AI-Native Lakehouse

Modern data organizations have moved beyond big data analytics to also incorporate advanced AI/ML data workloads. These workflows often involve multimodal datasets containing documents, images, long-form text, embeddings, URLs and more. Unity Catalog is an ideal solution for organizing and governing this data at scale. When paired with the Daft open source data engine, you can build a truly multimodal, AI-ready data lakehouse. In this session, we’ll explore how Daft integrates with Unity Catalog’s core features (such as volumes and functions) to enable efficient, AI-driven data lakehouses. You will learn how to ingest and process multimodal data (images, text and videos), run AI/ML transformations and feature extractions at scale, and maintain full control and visibility over your data with Unity Catalog’s fine-grained governance.
