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.

Configuring data sources

We're all set and ready to roll! We will build the Electroniz lakehouse one layer at a time starting with the bronze layer. The problem is that we do not have any data. Since this is a learning exercise, we will generate our own data; however, most likely, data will preexist for you when you work on actual customer projects.

Data preparation

To proceed with the lakehouse creation, we will create the following data sources with sample data:

  • The stores database: This is stored in Microsoft SQL Server.
  • E-commerce transactions: These are pushed to Azure Event Hubs.
  • The e-commerce website tracking: This is downloaded from an Azure Blob storage location.

There is no need to generate data for the following datasets because they are downloaded in real time from external sources:

  • Currency conversion data: This is downloaded from a REST API.
  • Geo-location data: This is downloaded from an HTTP source.
