Serverless Analytics with Amazon Athena

By: Anthony Virtuoso, Mert Turkay Hocanin, Aaron Wishnick

Overview of this book

Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using SQL, without needing to manage any infrastructure. This book begins with an overview of the serverless analytics experience offered by Athena and teaches you how to build and tune an S3 Data Lake using Athena, including how to structure your tables using open-source file formats like Parquet. You’ll learn how to build, secure, and connect to a data lake with Athena and Lake Formation. Next, you’ll cover key tasks such as ad hoc data analysis, working with ETL pipelines, monitoring and alerting KPI breaches using CloudWatch Metrics, running customizable connectors with AWS Lambda, and more. Moving on, you’ll work through easy integrations, troubleshooting and tuning common Athena issues, and the most common reasons for query failure. You will also review tips to help diagnose and correct failing queries in your pursuit of operational excellence. Finally, you’ll explore advanced concepts such as Athena Query Federation and Athena ML to generate powerful insights without needing to touch a single server. By the end of this book, you’ll be able to build and use a data lake with Amazon Athena to add data-driven features to your app and perform the kind of ad hoc data analysis that often precedes many of today’s ML modeling exercises.

Summary

In this chapter, you got hands-on with the first of Athena's four most common usages – ad hoc analytics. We did this by looking at the history of business intelligence and learning about the OODA loop. Ad hoc analytics shortens the OODA loop by making it easier to use data to observe and orient yourself to the situation. The increased accessibility of data ultimately leads to the heightened situational awareness required for making sound decisions. With clarity of data behind your decisions, your organization will be less likely to waste time before acting on those choices. A short OODA loop also helps you react to poor decisions or calculated risks such as A/B tests.

The OODA loop isn't a new concept, and it's not the catalyst of the rising importance of ad hoc analytics. Instead, the proliferation of data has made it necessary for every decision maker in your organization to have access to critical business metrics at a moment's notice. We saw...
