By: Nagaraj Venkatesan, Ahmad Osama

Overview of this book

The famous quote 'Data is the new oil' seems more true every day as the key to most organizations' long-term success lies in extracting insights from raw data. One of the major challenges organizations face in leveraging value out of data is building performant data engineering pipelines for data visualization, ingestion, storage, and processing. This second edition of the immensely successful book by Ahmad Osama brings to you several recent enhancements in Azure data engineering and shares approximately 80 useful recipes covering common scenarios in building data engineering pipelines in Microsoft Azure. You’ll explore recipes from Azure Synapse Analytics workspaces Gen 2 and get to grips with Synapse Spark pools, SQL Serverless pools, Synapse integration pipelines, and Synapse data flows. You’ll also understand Synapse SQL Pool optimization techniques in this second edition. Besides Synapse enhancements, you’ll discover helpful tips on managing Azure SQL Database and learn about security, high availability, and performance monitoring. Finally, the book takes you through overall data engineering pipeline management, focusing on monitoring using Log Analytics and tracking data lineage using Azure Purview. By the end of this book, you’ll be able to build superior data engineering pipelines along with having an invaluable go-to guide.

Connecting a Databricks Delta Lake table to Power BI

Delta Lake databases are commonly used to store processed data in Delta Lake tables, which is then ready to be consumed by reporting-layer applications such as Power BI. Delta Lake tables are best suited for handling analytic workloads from Power BI, as Delta Lake tables use Parquet files as storage, which offer optimal performance for analytic workloads.

In this recipe, we will use Power BI Desktop, connect to a Delta Lake table, and build a simple report in Power BI.

Getting ready

Create a Databricks workspace and a cluster as explained in the Configuring the Azure Databricks environment recipe.

Download the latest version of Power BI Desktop from https://powerbi.microsoft.com/en-us/downloads/ and install Power BI Desktop on your machine.

How to do it…

Perform the following steps to connect a Delta Lake table to a Power BI report and create visualizations:

  1. Log in to the Databricks portal and click...
