Without any requirement of aggregate or else load the data into the AWS Athena, it can be directly used for running the ad-hoc queries with the help of ANSI SOL. In a bid to offer tenacious metadata store for your required amount of data in Amazon S3, this AWS Athena can also integrate with the AWS Glue Data Catalog.

Based upon the Central metadata store throughout the AWS account, AWS integration with ETL and the AWS Glue data discovery features, this process will help you to create query data and tables on the required purpose. In an order to have a data visualization with ease, this AWS Athena also integrates with AWS QuickSight. The named queries can also be created with the help of AWS Cloud Formation and run the queries in Athena with no-time. In such process, the named query will generally map with another query and will able to call the plenty of queries by taking the name as its reference.
