Connecting to Power BI

This topic describes how to connect Microsoft Power BI to MemSQL.

Data Connectivity Modes

Using the MemSQL Direct Query Connector in Power BI, you can connect to a MemSQL data source in Import or DirectQuery mode.

When you use Import mode, PowerBI imports the data from the data source. If the data in the data source changes, you will need to refresh the data source to see the changes.

When you use DirectQuery mode, you work directly with the data source.

For a further explanation of the Import and DirectQuery modes, see this article.
