What service provides the ability to run SQL queries on multiple Amazon S3 files?

Amazon Athena is a serverless interactive query service that enables users to run SQL queries directly against data stored in Amazon S3. This service is particularly advantageous because it allows for the querying of various file formats, such as CSV, JSON, Parquet, and ORC, without the need for complex data loading processes.

By leveraging Presto, an open-source distributed SQL query engine, Athena processes the queries on the fly, allowing users to analyze and gain insights from their data quickly and efficiently. Users pay only for the queries they run and the amount of data scanned, which makes it a cost-effective solution for data analysis in the cloud.

This capability is essential for analytics workflows that require flexibility and scalability while working with large datasets stored in S3, facilitating the combination of data from multiple files and sources seamlessly. The other services listed, while valuable in their own right, either do not provide SQL querying capabilities on S3 files or require different setups or infrastructure to achieve similar analytics tasks.
