StarRocks

Last updated Oct 1, 2026 Below is an example of using StarRocks ↗︎ to connect, query, modify data from Basin Catalog (read-write).

Prerequisites

• Sign up for a Cloudflare account ↗︎.
• Create an R2 bucket and enable the data catalog.
• Create an R2 API token with both R2 and data catalog permissions.
• A running StarRocks ↗︎ frontend instance. You can use the all-in-one ↗︎ docker setup.

Example usage

In your running StarRocks instance, run these commands:

-- Create an Iceberg catalog named `r2` and set it as the current catalog

CREATE EXTERNAL CATALOG r2
PROPERTIES
(
    "type" = "iceberg",
    "iceberg.catalog.type" = "rest",
    "iceberg.catalog.uri" = "<r2_catalog_uri>",
    "iceberg.catalog.security" = "oauth2",
    "iceberg.catalog.oauth2.token" = "<r2_api_token>",
    "iceberg.catalog.warehouse" = "<r2_warehouse_name>"
);

SET CATALOG r2;

-- Create a database and display all databases in newly connected catalog

CREATE DATABASE testdb;

SHOW DATABASES FROM r2;

+--------------------+
| Database           |
+--------------------+
| information_schema |
| testdb             |
+--------------------+
