Overview of this book

In the world of ever-changing data and schemas, it is important to build data pipelines that can auto-adjust to changes. This book will help you build scalable data platforms that managers, data scientists, and data analysts can rely on. Starting with an introduction to data engineering, along with its key concepts and architectures, this book will show you how to use Microsoft Azure Cloud services effectively for data engineering. You'll cover data lake design patterns and the different stages through which the data needs to flow in a typical data lake. Once you've explored the main features of Delta Lake to build data lakes with fast performance and governance in mind, you'll advance to implementing the lambda architecture using Delta Lake. Packed with practical examples and code snippets, this book takes you through real-world examples based on production scenarios faced by the author in his 10 years of experience working with big data. Finally, you'll cover data lake deployment strategies that play an important role in provisioning the cloud resources and deploying the data pipelines in a repeatable and continuous way. By the end of this data engineering book, you'll know how to effectively deal with ever-changing data and create scalable data pipelines to streamline data science, ML, and artificial intelligence (AI) tasks.

Verifying aggregated data in the gold layer

Assuming the previous invocation of electroniz_batch_aggregation_pipeline was successful, you should see the following external tables and views in the silver container of the Azure Data Lake Storage account:

  1. Using the Azure portal, navigate to Home > All Resources > trainingsynapse100.

    Now, click on Open in the Open Synapse Studio section:

    Figure 8.31 – The Open Synapse Studio section

  2. Using the menu on the left, click on Data. Now, keep clicking on the arrow beside Database, then gold (SQL) and External Tables.

    You should now see the following pane:
