The data queried by Athena can cross day boundaries and also include CIs billed in adjacent months. When calling this command, we’ll specify table columns that match the format of the AWS Config configuration snapshot files so that Athena knows how to query and parse the data. Hive has no concept of enums. Hive supports most of the primitive data types supported by many relational databases and even if anything are missing, they are being added/introduced to hive in each release. The response also captures the run time and the data scanned which are incredibly useful for estimating costs and optimizing queries. fetchall in PEP 249 - fetchall_athena.
