    • The Apache Iceberg connector provides read-only access to data and metadata in the Iceberg format.

    A connection admin can set up a connection to Apache Iceberg in the Workflow Data Fabric Hub and grant data stewards access to this connection. Data stewards can then use the established connection to create a data fabric table and map data from Apache Iceberg. This allows users to access Apache Iceberg data through the table list view or by using GlideRecord scripts. For details on creating data fabric tables and mapping data, see Managing data fabric tables in Workflow Data Fabric Hub.

    The connector has been enhanced to improve the performance of the following Glide queries and list view operations. These improvements allow the majority of queries to be executed at the data source.

    • Sort
    • Limit
    • Filter
    • GroupBy
    • avg()
    • count()
    • max()
    • min()
    • sum()
