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.

Connecting and securing

Connectivity and authentication features are often overlooked. Like all AWS services, Athena offers a set of APIs for interacting with the service from your applications or from the command line when using the AWS CLI. These APIs allow you to submit a new query, check the status of an already running query, retrieve pages of results, or kill a query. These same APIs are used from within Athena's JDBC and ODBC drivers. When connecting to Athena, you can use the standard endpoints if you have an internet gateway in your VPC or opt to call Athena from a VPC endpoint and avoid the need to have internet connectivity from your application VPC. This gives you added control over your security posture by pushing the responsibility of securely connecting to your data sources onto Athena.

In addition to VPC endpoints, Athena also offers SAML federation for managing identities outside of AWS. This allows your Active Directory users to seamlessly authenticate to...
