  Option C Cost-effectiveness: Amazon Athena allows you to query data directly from Amazon S3 without the need for any infrastructure setup or management. You pay only for the queries you run, making it cost-effective, especially for sporadic or exploratory analysis. Flexibility: Since the data structure can change with IoT device upgrades, using Athena allows for flexibility in querying and analyzing the data regardless of its structure. You don't need to define a fixed schema upfront, enabling you to adapt to changes seamlessly. Apache Spark Support: Athena supports querying data using Apache Spark, which is powerful for processing and analyzing large datasets. This capability ensures that the analytics department can leverage Spark for more advanced analytics if needed. https://www.youtube.com/watch?v=Q93NZJBFSWw
