- * Iceberg Catalog Service API: this implements the open-source Iceberg REST

- * See the API definition here:
- * https://github.com/apache/iceberg/blob/main/open-api/rest-catalog-open-api.yaml
- * The API is defined as OpenAPI 3.1.1 spec.
- * Currently we only support the following methods:
- * - GetConfig/GetIcebergCatalogConfig
- * - ListIcebergNamespaces
- * - CheckIcebergNamespaceExists
- * - GetIcebergNamespace
- * - CreateIcebergNamespace (only supports single level)
- * - DeleteIcebergNamespace
- * - UpdateIcebergNamespace properties
- * - ListTableIdentifiers
- * - CreateIcebergTable
- * - DeleteIcebergTable
- * - GetIcebergTable
- * - UpdateIcebergTable (CommitTable)
- * - LoadIcebergTableCredentials
- * - RegisterTable
- * Users are required to provided the `X-Goog-User-Project` header with the
- * project id or number which can be different from the bucket project id.
- * That project will be charged for the API calls and the calling user must have
- * access to that project. The caller must have `serviceusage.services.use`
- * permission on the project.
+ * Lakehouse runtime catalog supports the following catalog management methods:
+ * - GetIcebergCatalog
