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!

Building Transactional Data Lakes

In the last few years, new technologies have emerged that have significantly enhanced the capabilities of traditional data lakes, enabling them to operate similarly to a data warehouse. These new technologies provide all the benefits of data lakes (such as low-cost object storage, and the ability to use serverless data processing services) while also making it much easier to update data in the data lake (amongst other benefits).

Traditional data lakes were built on the Apache Hive technology stack, which enables you to store data in various file formats (such as CSV, JSON, Parquet, and Avro). Hive enabled many tens of thousands of data lakes to be built on object storage, but over the years the limitations of Hive became more clear, as we will discuss in this chapter.

To overcome these limitations, a number of new table formats have been created by a number of different companies and open-source organizations. Keep reading to learn more...
