Managed Apache Iceberg at scale: How Spanner powers Lakehouse runtime catalog

As customers modernize to lakehouse architectures, they are standardizing on open formats such as Apache Iceberg to create a shared data estate across compatible engines. This enables you to build AI-native lakehouses that turn data to semantic knowledge, enable proactive action, and operate at an agentic scale. One of the key components of a lakehouse is the catalog, and in the Apache Iceberg environment, that usually means the Iceberg REST Catalog.
