**Presentation Info**

* *Powering Region-Agnostic Machine Learning with a Universal Data Catalog*
The increasing demand for GPU resources in modern machine learning workloads is often challenged by their scarcity and the distributed nature of data and storage. Specifically, GPUs are frequently located remotely from the data they need to process, which may reside in on-premises HDFS or cloud-based storage like GCS. This talk addresses this challenge by introducing a solution that leverages a Catalog to provide a region-agnostic interface. This approach abstracts the underlying data location, enabling training pipelines to seamlessly access data from either on-premises HDFS or GCS in the Cloud. By decoupling compute from storage location, this solution enhances GPU utilization and streamlines the training process in distributed environments.
* *Toward a Unified Data Catalog at OpenAI*
In this talk, we’ll share how OpenAI is building a unified data catalog as part of its evolving data infrastructure. We’ll cover the technical journey of abstracting over Databricks Unity Catalog to enable seamless transition between Databricks Spark and open-source Spark. Along the way, we’ll dive into our caching layer for Delta Lake metadata and the unified access control system we developed. We’ll also discuss our long term vision: moving towards a self-hosted, open-source catalog backed by open table formats, enabling flexibility, performance, and vendor neutrality at scale
* *Advancing Toward an Intelligent and Agentic Data Architecture with Apache Gravitino*
While data stacks have advanced over the past 20 years to handle big data’s "3Vs" (Volume, Velocity, Variety), their query-centric design remains a bottleneck for the generative AI era. We propose a shift to metadata-centric architectures—exemplified by ​Apache Gravitino—to unlock interpretability, intelligence, and adaptability. This presentation demonstrates how Gravitino’s metadata-driven approach enables agentic data systems, with real-world examples of collaborative data agents solving governance and management challenges. We also explore future integrations with LLMs to automate and evolve data ecosystems into truly intelligent platforms.
* *Building an interoperable Lakehouse with Unity Catalog*
What connects your lakehouse to real data intelligence? The answer: the catalog. Today's data driven organizations have high demands for their lakehouse catalogs; everything from support for multiple table formats to advanced governance and compliance requirements to end to end lineage between their AI models and the source data that powers them. Unity Catalog is purpose-built for the lakehouse and goes beyond operational or business catalogs to deliver cross-platform interoperability and a shared understanding of the entire data estate.
