Connect to Data in an Iceberg Catalog Table

If you have data tables in Apache Iceberg format, you can connect to that data by configuring a connection to the data from LiveRamp Clean Room.

Note

  • This connection type currently uses AWS Glue Catalog as the mechanism for connecting to the Iceberg tables. Other catalog types will be available in the future.

  • For information on how LiveRamp Clean Room interprets the data types from Glue Catalog, see “Glue Catalog”.

Once you've connected to your Iceberg Catalog data, those datasets can be used in Hybrid and Confidential Computing clean rooms.

To configure an Iceberg Catalog data connection, see the instructions below.

Overall Steps

    • Name: Enter a name of your choice.

    • Category: Enter a category of your choice.

    • Dataset Type: Select Generic.

    • Catalog Type: Select GLUE.

    • Database Name: Enter the name of the database that contains your data.

    • Table Name: Enter the name of the Apache Iceberg table.

    • Catalog Name: Enter the name of the AWS account that contains the Iceberg table.

  6. Review the data connection details and click Save Data Connection.

    Note

    All configured data connections can be seen on the Data Connections page.

When a connection is initially configured, it will show "Verifying Access" as the configuration status. Once the connection is confirmed and the status has changed to "Mapping Required", map the table's fields.

You will receive file processing notifications via email.

Map the Fields

Once the connection is confirmed and the status has changed to "Mapping Required", map the table's fields and add metadata:

  1. From the row for the newly created data connection, click the More Options menu (the three dots) and then click Edit Mapping.

    The Map Fields screen opens, and the file column names auto-populate.

  2. For any columns that you do not want to be queryable, slide the Include toggle to the left.

  3. Click Next.
