Process & Analyze Power BI XMLA Data in Databricks (AWS)

Databricks is a cloud-based service that provides data processing capabilities through Apache Spark. When paired with the CData JDBC Driver, customers can use Databricks to perform data engineering and data science on live Power BI XMLA data. This article walks through hosting the CData JDBC Driver in AWS, as well as connecting to and processing live Power BI XMLA data in Databricks.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Power BI XMLA data. When you issue complex SQL queries to Power BI XMLA, the driver pushes supported SQL operations, like filters and aggregations, directly to Power BI XMLA and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Power BI XMLA data using native data types.

Install the CData JDBC Driver in Databricks

To work with live Power BI XMLA data in Databricks, install the driver on your Databricks cluster.

1. Navigate to your Databricks administration screen and select the target cluster.
2. On the Libraries tab, click "Install New."
3. Select "Upload" as the Library Source and "Jar" as the Library Type.
4. Upload the JDBC JAR file (cdata.jdbc.powerbixmla.jar) from the installation location (typically C:\Program Files\CData[product_name]\lib).

Access Power BI XMLA Data in your Notebook: Python

With the JAR file installed, we are ready to work with live Power BI XMLA data in Databricks. Start by creating a new notebook in your workspace. Name the notebook, select Python as the language (though Scala is available as well), and choose the cluster where you installed the JDBC driver. When the notebook launches, we can configure the connection, query Power BI XMLA, and create a basic report.

Configure the Connection to Power BI XMLA

Connect to Power BI XMLA by referencing the JDBC Driver class and constructing a connection string to use in the JDBC URL. Additionally, you will need to set the RTK property in the JDBC URL (unless you are using a Beta driver). You can view the licensing file included in the installation for information on how to set this property.

Step 1: Connection Information

driver = "cdata.jdbc.powerbixmla.PowerBIXMLADriver"
url = "jdbc:powerbixmla:RTK=5246...;AuthScheme=AzureADInitiateOAuth=GETANDREFRESH"

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Power BI XMLA JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

Fill in the connection properties and copy the connection string to the clipboard.

By default, use Azure AD to connect to Microsoft Power BI XMLA. Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.

For more information on other authentication schemes, refer to the Help documentation.

Load Power BI XMLA Data

Once you configure the connection, you can load Power BI XMLA data as a dataframe using the CData JDBC Driver and the connection information.

Step 2: Reading the data

remote_table = spark.read.format ( "jdbc" ) \
	.option ( "driver" , driver) \
	.option ( "url" , url) \
	.option ( "dbtable" , "Customer") \
	.load ()

Display Power BI XMLA Data

Check the loaded Power BI XMLA data by calling the display function.

Step 3: Checking the result

display (remote_table.select ("Country"))

Analyze Power BI XMLA Data in Databricks

If you want to process data with Databricks SparkSQL, register the loaded data as a Temp View.

Step 4: Create a view or table

remote_table.createOrReplaceTempView ( "SAMPLE_VIEW" )

With the Temp View created, you can use SparkSQL to retrieve the Power BI XMLA data for reporting, visualization, and analysis.

% sql

SELECT Country, Education FROM SAMPLE_VIEW ORDER BY Education DESC LIMIT 5

The data from Power BI XMLA is only available in the target notebook. If you want to use it with other users, save it as a table.

remote_table.write.format ( "parquet" ) .saveAsTable ( "SAMPLE_TABLE" )
