In a future world where agents interact with billions of users, many of these agents will also have to interact with data querying tools to provide answers grounded in facts. As enterprise data analytics is rapidly moving towards open table formats like Apache Iceberg, these agents need to be able to speak to Iceberg-based data. Once agents can speak Iceberg, they gain an advantage – they become portable. They can run in public clouds, locally on a laptop (during development), or on-premise, accessing enterprise data that can’t be moved to public clouds. Portability is important because, while Nvidia GPUs dominate in the cloud, the GPU stack looks different on-premises and on consumer hardware. In this talk, we will discuss how Apache Iceberg tooling and portable application runtimes make agents grounded in facts and enable them to run across different GPU stacks and deployment models.
