2017/05/18 - Amazon Athena - 11 new api methods
Changes This release adds support for Amazon Athena. Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run.
Stops a query execution.
For code samples using the AWS SDK for Java, see Examples and Code Samples in the Amazon Athena User Guide .
