Installing the DuckDB Extension

Warning

Make sure to match the module version with your GeoServer version.

1. Login, and navigate to About & Status > About GeoServer and check Build Information to determine the exact GeoServer version in use.

2. Visit the website download <download> page, switch to the Development tab, and locate the nightly build matching your GeoServer version.

3. Follow the Community Modules link and download the DuckDB module:

   • {{ version }} example: duckdb

   The website lists active nightly builds to provide feedback to developers. You may also browse for earlier branches.

4. Extract the downloaded archive into WEB-INF/lib of your GeoServer installation.

5. Restart GeoServer.

Note

If the GeoParquet community module is already installed, the DuckDB JDBC driver may already be present. You still need to install the DuckDB extension to register the DuckDB store type in GeoServer.

Verification

After restart:

1. Open Stores > Add new Store.
2. Confirm DuckDB appears under vector data sources.
