Test with a sample use case

Visualization of cost per employee

The dataset for this use case is stored in BLOB storage in Azure (Home > Storage accounts > canopydata> defloc). Tables are created and made readily available to users on their default database. More information on the tables is found in the Tables tab.

  1. Launch Power BI. At the top left corner on the home tab, click Get Data.

  3. Click Connect to open the Qubole Connector dialog.

    • Enter the DSN (Data Source Name), which is available in ODBC configuration. For example: Qubole ODBC Driver DSN 64.

    • In Data Connectivity Mode field, select the DirectQuery radio button and click OK.

  5. Click Edit. This initiates a query to extract required data sets from the data source. Transform the raw data by filtering, sorting, and cleaning.

    Example

    Suppose the user is only interested in selected columns from the table. Data can be transformed using options provided on the table icon below the formula bar in the left corner. Click Table Icon followed by Choose Columns. Tick the required columns. A query that filters the required columns will be initiated and the data will be refreshed.

  6. After the transformation is done, the desired data is ready for visualization. Close the Edit window, and save for further analysis.

  7. Tables are listed in the right pane in the FIELDS section. Select the fields listed under the table for visualization. Here, employee_name and employee_salary are selected in the Staples table.

    You have now successfully created your first Power BI visualization with direct connection to Qubole services.

  9. You can publish the visualization created to Power BI app to be shared with others. Click Publish in the top panel.

    Before proceeding to view the dashboard created on Power BI app, make sure that you have installed an on premise or enterprise gateway. You can find the details here: Power BI.

  11. Configure the gateway for the Qubole Connector.

    1. Once the gateway is installed, sign in with your Microsoft credentials. Navigate to the Connectors section, as shown below, and provide the path where the mez file is placed. (Make sure this location is accessible to everyone on the system.)

    2. The QubolePresto connector name will appear as shown in the image above.

  12. Click the Open “<Dashboardname.pbix> in Power BI” link. This will take you to Power BI app.

  13. Once you are on Power BI app, click Settings in the top right hand corner:

    ../../../_images/27_settings1.png

  14. Click Manage gateways.

  19. Click Datasets, and select the datasets you uploaded from Power BI.

    ../../../_images/35_datasets1.png

  20. Make sure the gateway you added is associated with the dataset.
