Learn about RisingWave’s hosted JDBC and REST catalog options for internal Iceberg tables.
When creating internal Iceberg tables, you can use one of RisingWave’s two built-in hosted catalog options. A hosted catalog simplifies setup by managing Iceberg metadata directly within RisingWave, eliminating the need to deploy and manage an external catalog service like AWS Glue or a separate Hive Metastore.This is the recommended approach for getting started with internal Iceberg tables.
RisingWave supports two types of hosted catalogs, each based on a standard Iceberg protocol:
JDBC Hosted Catalog: Utilizes RisingWave’s internal PostgreSQL-compatible metastore to function as a standard Iceberg JDBC catalog. This is the simplest option with zero external dependencies.
REST Hosted Catalog: Provides a REST API endpoint for catalog operations, powered by the integrated Lakekeeper service.
