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 process of aggregating data

Although the objective of data aggregation is largely straightforward, you should follow a definitive process. The data aggregation process is a co-shared responsibility between the customer and the data engineer. Each entity needs to contribute toward the objective through a combination of business and technical knowledge:

This process can be explained as follows:

  • Define KPIs: The process of data aggregation starts by defining the key performance indicators (KPIs). Data engineers are not the best resources for making such business-oriented decisions. Therefore, it is important to seek customer help on this one since they are closer to the business and can make these decisions more accurately.

    A quantifiable metric that's used to measure a company's success or failure is called a KPI. KPIs are often used to evaluate whether the company has met its objectives...
