Arrow Database Connectivity (ADBC) driver for Power BI

Preview

This feature is in Public Preview.

This page describes how to switch to the Arrow Database Connectivity (ADBC) driver for Power BI dashboards that connect to Databricks data sources. The ADBC driver is a modern, columnar API standard designed for analytical applications, enabling efficient data transfer between databases and client tools using the Apache Arrow format.

You can use the ADBC driver instead of the ODBC driver for the Databricks connector in Power BI. To use the ADBC driver, use Power BI Desktop 2.145.1105.0 (July 2025 release) or above.

Databricks continues to enhance this connector and add new capabilities. Upgrade to the latest version, try it out, and Submit product feedback.

         [Catalog=null, Database=null, EnableAutomaticProxyDiscovery=null, Implementation="2.0"]),
        powerbi_Database = Source{[Name="powerbi",Kind="Database"]}[Data],
        default_Schema = powerbi_Database{[Name="default",Kind="Schema"]}[Data],
