What is the application and application of AWS Athena service?

By reading the AWS Athena documentation - we realize that this service provides a way to make queries on stored files in S3 through traditional SQL and without going through an ETL. That's the basic idea.

But I do not know exactly what motivation to use this service is. Is it some kind of Elastic service?

No, it would be more like an external table in a Hive or Oracle, for example.

You use Glue Crawler to do the infer schema and store the metadata. From there, just do select * from sua_tabela; .
