Athena is not a database and it's a query engine .In Athena compute and storage are separate where as in the case of a database both are tightly coupled. Athena 不是一个数据库，它是一个查询引擎。在 Athena 中，计算和存储是分开的，而在数据库的情况下，两者都是紧密耦合的。
Athena is more of a OLAP solution where as relational DB is OLTP and it is fully managed service. Athena 更像是一个OLAP解决方案，其中关系数据库是OLTP ，它是完全托管的服务。 It will also not maintain the metadata and instead use Glue catalog to store and reteive it.它也不会维护元数据，而是使用 Glue 目录来存储和检索它。
