Released: December 04th, 2017

The following describes the enhancements and bug fixes in RapidMiner Server 8.0.0:

Important notes

The process execution on RapidMiner Server has fundamentally changed. Please visit this page for more information before upgrading!

New features

  • Processes are no longer executed inside RapidMiner Server itself but instead run externally. The process execution is managed by so called Job Agents, which do not need to run on the same machine as RapidMiner Server. This allows for total horizontal scalability of process execution.


  • License expiration warnings are no longer shown if an upcoming license is available.
  • Webservices can no longer sometimes block the entire RapidMiner Server instance despite using almost no CPU or memory resources. For faster performance, they also now run single-threaded by default (each web service uses only 1 CPU core). To enable parallel execution, set the property com.rapidanalytics.webservices.concurrency to the number of threads that should be used by each web service call. Please be sure to read the information available here before doing so!
  • It is now possible to change the target queue of scheduled processes via the UI.
  • Scheduled Processes now display a warning if their queue does not exist anymore/has no Job Agents connected to it.
  • Triggers list now has tooltips.
  • Triggers now display a warning if their queue does not exist anymore/has no Job Agents connected to it.
