Outline Athena is a managed Prestodb offering from aws, it primarily serves the purpose of query execution/data exploration against Hive DDL predefined databases (namespaces). In order to quick-dive to Athena we’ll use terraform to provision the necessary resources needed for a basic functional setup, then we’ll process and convert a dimensional like data set from csv to parquet format, create & apply DDL statements on top of our data, run some analytical queries and and finally look at further recommendations and other common use cases.
