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!

Ad Hoc Queries with Amazon Athena

In Chapter 8, Identifying and Enabling Varied Data Consumers, we explored a variety of data consumers. Now in this chapter, we will start examining the AWS services that some of these different data consumers may want to use, starting with those that need to use SQL to run ad hoc queries on data in the data lake.

SQL syntax is widely used for querying data in a variety of databases, and there is a large number of people that know SQL, making it a skill that is fairly easy to find. As a result, there is significant demand from various data consumers for the ability to query data that is in the data lake using SQL, without having to first move the data into a dedicated traditional database.

Amazon Athena is a serverless, fully managed service that lets you use SQL and Spark to directly query data in the data lake, as well as query various other database sources. It requires no setup, and there are options to either pay for the service based...
