Visualize Live Presto Data in Power BI (via CData Connect Cloud)

Power BI transforms your company's data into rich visuals for you to collect and organize so you can focus on what matters to you. When paired with CData Connect Cloud, you get access to Presto data for visualizations, dashboards, and more. This article shows how to use CData Connect to create a live connection to Presto, connect to Presto data from Power BI and then create reports on Presto data in Power BI.

Configure Presto Connectivity for Power BI

Connectivity to Presto from Power BI is made possible through CData Connect Cloud. To work with Presto data from Power BI, we start by creating and configuring a Presto connection.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.

With the connection configured, you are ready to connect to Presto data from Power BI.
