While Amazon Athena itself does not provide a DB API 2.0 (PEP 249) compliant connection, the PyAthena library offers this functionality, building upon the boto3 library. + +This documentation covers two primary ways to interact with Amazon Athena with Airflow: + +1. API (HTTP Boto3): This method uses Amazon Athena's direct API through the boto3 library. It is the preferred method for users who wish to interact with Athena at a lower level, directly through HTTP requests. + +2. DB API Connection (Amazon Athena SQL): For users who prefer a more traditional database interaction, PyAthena implements the DB API 2.0 specification, allowing Athena to be used similarly to other relational databases through SQL. + +Choosing Your Connection Method +========================= +**Amazon Athena (API):** Choose this option if you need to execute a single statement without bringing back the results in airflow. + +**Amazon Athena SQL (DB API Connection):** Opt for this if you need to execute multiple queries in the same operator and it's essential to retrieve and process query results directly in Airflow, such as for sensing values or further data manipulation. Review Comment: I think that the choice between AthenaHook and AthenaSqlHook is only about functionality. AthenaSqlHook bring the results to the Airflow Worker. AthenaHook only executes a query without returning the data to the worker. Since AthenaHook and AthenaSqlHook depends on AwsBaseHook, both should support IAM role.
