Amazon Athena Connector

Options

Connection settings

Database Dialect

Choose the registered database dialect here.

Database Driver

Choose the JDBC driver to connect to the database here. Due to license restriction you need to download the Athena JDBC driver from Amazon and register it yourself. To download the driver please click here and download the latest version of the JDBC driver without the AWS SDK e.g. AthenaJDBC42-2.0.35.1001.jar. Once downloaded register the driver via the KNIME preference page with athena as database type as described in the Register your own JDBC drivers section of the KNIME Database Extension Guide.

If you select "Use latest driver version available" upon execution the node will automatically use the driver with the latest (highest) driver version that is available for the current database type. This has the advantage that you do not need to touch the workflow after a driver update. However, the workflow might break in the rare case that the behavior of the driver e.g. type mapping changes with the newer version.

If this option is not enabled, you can select a specific version of the registered drivers via the drop-down list. Additional drivers can be registered via KNIME's preference page "KNIME -> Databases". For more details on how to register a new driver see the database documentation.
