This section explains how to connect RapidMiner to an Exasol database and import data from Exasol to RapidMiner.

RapidMiner allows you to create visual workflows using data from an Exasol database. RapidMiner can be integrated with Exasol using the Exasol JDBC connector.

For more information about RapidMiner, see RapidMiner Documentation.

Exasol takes no responsibility for any changes in functionality or terms of use for the third-party software described in this section. For more information, refer to the respective software vendor’s website.


The following procedure uses RapidMiner Studio 9.7 for Windows.


  • A running Exasol SaaS database. For more information, see Manage Database and Clusters.
  • The IP address of the host where the tool is running must be in the allowed IP address list. For more information, see Network Security.
  • Exasol JDBC driver is installed
  • RapidMiner Studio is installed

Get JDBC Driver and Connection Details

To connect to your Exasol SaaS database from a tool you need a valid connection string. You must also allow network access to the database from the tool, and make sure that the latest Exasol JDBC driver is installed.

  1. On the Databases page in the web console, click on Connect via tools on the cluster that you want to connect to.

    connect via tools

  2. In the wizard, enter the IP address of the client or server that will connect to the database and click Add IP, then click Next. This will add the IP address to the list of IP addresses that are allowed network access to the cluster. The allow list is found on the Security page in the web console. For more information, see Network Security.

    If the IP address is already present in the allow list, just click Next.

    enter ip address

  3. If the latest JDBC driver for your operating system is not already installed, select the driver type and operating system and click on Download to download the latest driver to your local system. For more information about how to install the driver, see JDBC Driver.
