The Lakehouse runtime catalog is compatible with Apache Flink to provide
centralized metadata for Google Cloud Lakehouse. You can connect Apache Flink
to the Lakehouse runtime catalog using the
Apache Iceberg REST catalog endpoint endpoint, which provides a standard
interface to discover and manage Apache Iceberg tables.
To learn more about how to configure Apache Flink to use the Apache Iceberg
REST catalog endpoint, see the official Apache Iceberg Flink
documentation.
