Use Cases and Deployment Scope
In my current organization, we use Amazon Athena for querying data from AWS S3 location. It provides faster access to data as compared to the traditional relational database management system. Also, it helps to work with complex data structures such as JSON, Parquet, CSV, and Avro. Earlier we were using some traditional RDBMS for reporting Ecommerce related KPIs which has lots of transactional data coming in. Performance was not much good for querying huge amount of real-time inventory data. So, we moved to Amazon Athena to support fast interactive querying of data and processing.
