Amazon Athena is now integrated with the AWS Glue Data Catalog. The AWS Glue Data Catalog provides a central metadata repository for all of your data assets regardless of where they are located. It integrates with Amazon S3, Amazon RDS, Amazon Redshift and Amazon Redshift Spectrum, Amazon Athena, Amazon EMR, and any Apache Hive Metastore compatible application. If you already use Amazon Athena, we recommend that you upgrade from using Athena’s internal Data Catalog to AWS Glue Data Catalog. Click here to learn more about the upgrade.
