 # Tutorial: Create a Power BI report using Apache Spark and Azure Synapse Analytics
 
-Organizations often need to process large volumes of data before serving to key business stakeholders. In this tutorial, you will learn how to leverage the integrated experiences in Azure Synapse Analytics to process data using Apache Spark and later serve the data to end-users through Power BI and Serverless SQL.

-In this example, you will use Apache Spark to perform some analysis on taxi trip tip data from New York. The data is available through [Azure Open Datasets](https://azure.microsoft.com/services/open-datasets/catalog/nyc-taxi-limousine-commission-yellow-taxi-trip-records/). This subset of the dataset contains information about yellow taxi trips, including information about each trip, the start and end time and locations, the cost, and other interesting attributes.

 1. Run the following lines to create a Spark dataframe by pasting the code into a new cell. This retrieves the data via the Open Datasets API. Pulling all of this data generates about 1.5 billion rows. The following code example uses start_date and end_date to apply a filter that returns a single month of data.
