Overview of this book

This book, authored by a seasoned Senior Data Architect with 25 years of experience, aims to help you achieve proficiency in using the AWS ecosystem for data engineering. This revised edition provides updates in every chapter to cover the latest AWS services and features, takes a refreshed look at data governance, and includes a brand-new section on building modern data platforms which covers; implementing a data mesh approach, open-table formats (such as Apache Iceberg), and using DataOps for automation and observability. You'll begin by reviewing the key concepts and essential AWS tools in a data engineer's toolkit and getting acquainted with modern data management approaches. You'll then architect a data pipeline, review raw data sources, transform the data, and learn how that transformed data is used by various data consumers. You’ll learn how to ensure strong data governance, and about populating data marts and data warehouses along with how a data lakehouse fits into the picture. After that, you'll be introduced to AWS tools for analyzing data, including those for ad-hoc SQL queries and creating visualizations. Then, you'll explore how the power of machine learning and artificial intelligence can be used to draw new insights from data. In the final chapters, you'll discover transactional data lakes, data meshes, and how to build a cutting-edge data platform on AWS. By the end of this AWS book, you'll be able to execute data engineering tasks and implement a data pipeline on AWS like a pro!

Transforming Data to Optimize for Analytics

In previous chapters, we covered how to architect a data pipeline and common ways of ingesting data into a data lake. We now turn to the process of transforming raw data in order to optimize the data for analytics, enabling an organization to efficiently gain new insights into their data.

Transforming data to optimize for analytics and create value for an organization is one of the key tasks for a data engineer, and there are many different types of transformations. Some transformations are common and can be generically applied to a dataset, such as converting raw files to Parquet format and partitioning the dataset. Other transformations use business logic in the transformations and vary based on the contents of the data and the specific business requirements.

In this chapter, we review some of the engines that are available in AWS for performing data transformations and also discuss some of the more common data transformations...
