As of April 20th, 2026, BigLake is now called Lakehouse for Apache Iceberg. BigLake metastore is now called the Lakehouse runtime catalog. Lakehouse APIs, client libraries, CLI commands, and IAM names remain unchanged and still reference BigLake.

Use Apache Spark with the Lakehouse runtime catalog

Apache Spark connects to Lakehouse for Apache Iceberg through the Lakehouse runtime catalog. This integration uses the Apache Iceberg REST catalog endpoint to provide a standard interface for discovering and managing tables.

To get started, see the following:

Set up the Lakehouse Iceberg REST catalog
Query Iceberg tables with Spark and BigQuery (Quickstart)

For configuration details, see the official Apache Iceberg Spark documentation.
