Lakehouse Iceberg REST catalog

Connect Foundry to Google Cloud Lakehouse through the Google Cloud Storage connector. Lakehouse is configured as an Iceberg catalog on a Google Cloud Storage source. The registered virtual tables use Iceberg format and point to tables in that Lakehouse catalog.

Setup

Lakehouse catalog setup is part of the Google Cloud Storage connector configuration. To configure Lakehouse, add the Catalog setting on a Google Cloud Storage source, then select Lakehouse Catalog.

You cannot use the same Google Cloud Storage source for both a Lakehouse catalog and bring-your-own-bucket (BYOB) Iceberg storage. Create a separate source for each workflow. Configure the Lakehouse source with Catalog set to Lakehouse Catalog, and configure the BYOB source without a Catalog setting.

See the Google Cloud Storage Lakehouse catalog setup instructions for authentication, networking, and source configuration details.

Register virtual tables

To register a table from Lakehouse, open the configured Google Cloud Storage source and register a virtual table with Format set to Iceberg. See the Google Cloud Storage registration instructions for the full workflow.
