How to integrate my Google Bigquery Warehouse with Power BI?


Power BI is a business intelligence (BI) tool, that allows you to connect to, transform, and visualize your data. There are many different types of visuals to choose from in Power BI according to the nature of data you are trying to graphically represent.

    1. If you choose the Import option, data from BigQuery will be copied to Power BI. This option offers to you the advantage of providing access to the full features of Power BI desktop. You can make manipulations/ transformations to your dataset without altering the original datasource. However, this method is not suitable if you want to refresh your dataset at a near real time frequency.

    2. If you choose the DirectQuery option, this will set up a live connection to this dataset. Since the data is synchronised, any change in BigQuery records will automatically be updated in Power BI. However, you can not make any manipulations/ transformations to your dataset using this mode.
