Snowflake unveils Open Warehouse to unify data lake and warehouse workloads

Snowflake demonstrated its Open Warehouse architecture, linking an Apache Iceberg data lake stored in Amazon S3 directly to Snowflake compute without moving data. The setup uses external volume definitions, AWS Glue catalog integration, and a catalog‑linked database that auto‑discovers tables, enabling zero‑copy governance, AI‑ready analytics through semantic views, and cost‑efficient storage on S3.

The broader data‑engineering landscape continues to shift toward lakehouse solutions that combine the flexibility of data lakes with the performance and governance of warehouses. Industry guides note that platforms such as Snowflake, Databricks, Delta Lake and Apache Iceberg are driving this trend, emphasizing scalability, security and AI‑ready pipelines for modern enterprises.
