Is a serverless service that can run queries in CSV, TSV, JSON, Parquet and ORC formats.

You can point Athena to a data lake on AWS S3 and run SQL queries and you can use AWS Glue as a metadata catalog and Quicksight for visualization.

There are also other options for data source ( both from AWS and other services ) but you will need a Lambda function to connect Athena to the data source and map the data into tables that Athena can query.
