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.

The need to aggregate data

Before we deep dive into how to aggregate data and build the gold layer of the Electroniz lakehouse, we should quickly remind ourselves why we're building the lakehouse in the first place. During the discovery phase, Electroniz had put forth some key business requirements, as follows:

  • They want to aim for a near-real-time sales analytics platform that can serve their customer needs faster and better.
  • They want to streamline their advertising budgets through intelligent analytics based on the number of user hits on their e-commerce website.
  • They want to decrease customer dissatisfaction because of interruptions in fulfilling orders due to inventory shortages.

Thus far, we have been able to identify, collect, and curate data from a variety of sources to help us perform intelligent decision-making using modern analytics. At this point, we have data in the silver layer that represents the state of the data that has been standardized...
