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.

Chapter 7: Data Curation Stage – The Silver Layer

The journey of data is now at a very critical stage. In this stage, the driver (data engineer) needs to carefully plan and maneuver the vehicle (data pipeline) around several roadblocks in such a way that the sanity, durability, and security of the data are preserved.

In the previous chapter, we performed a deep dive into Delta Lake. Understanding the Delta Lake functionality is a critical skill, as it enables the data engineer to design and develop the silver layer of the lakehouse. In this chapter, we will advance our understanding of how to cleanse raw data. We will start by learning the need for data curation, followed by building a data curation pipeline that can perform the cleaning work consistently and regularly.

In this chapter, we will cover the following topics:

  • The need for curating raw data
  • The process of curating raw data
  • Developing a data curation pipeline
  • Running the pipeline for the...
