The Simba Amazon Athena JDBC Connector provides access to all the catalogs and databases that are available on the Athena server, ensuring compatibility with standard BI tools. Amazon Athena provides catalogs that enable you to access the data source that is being queried. These catalogs contain databases, which correspond to JDBC schemas, and each database contains data that has been organized into tables. By default, if your query statement does not specify a catalog, the connector queries the data under the catalog named AwsDataCatalog. You can use the Catalog connection property to specify a different default catalog for your queries. For more information, see Catalog.
