Configuring a connection for JDBC driver version 2.1 for Amazon Redshift

You can use a JDBC driver version 2.1 connection to connect to your Amazon Redshift cluster from many third-party SQL client tools. The Amazon Redshift JDBC connector provides an open source solution. You can browse the source code, request enhancements, report issues, and provide contributions.

By default, the Amazon Redshift JDBC driver is configured to use TCP keepalives to prevent connections from timing out. You can specify when the driver starts sending keepalive packets or turn off the feature by setting the relevant properties in the connection URL. For more information about the syntax of the connection URL, see Building the connection URL.
