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. Athena uses the Glue Data Catalog, a managed repository, integrated with Amazon EMR, Amazon Athena, Amazon Redshift Spectrum, and AWS Glue ETL, to store metadata information, and automate schema discovery and schema version history. With the recent release of resource-based policies and resource-level permissions for the AWS Glue Data Catalog, you can restrict or allow Athena access to Data Catalog Objects such as databases and tables. Please note that you still need S3 policies to govern access to data stored in Amazon S3. Click here to learn more
