Converting Excel Worksheets to DMN

Decision Model and Notation (DMN) is the new kid on the block when it comes to defining decisions and business rules. Like BPMN and CMMN, it tries to bridge the gap between human readable definition of business-relevant aspects and technical realization. DMN therefore has a graphical representation as well as an XML-based serialization format and Camunda provides you with a beautiful editor to manage both. So why not go full DMN any minute now? Probably because you work with business rule definitions for much longer than DMN is around and you manage them in Excel. Recreating these with the DMN editor is a tedious task. That is where Camunda’s newest community extension comes into play: The Excel worksheet to DMN…

Job Executor Improvements in Camunda BPM 7.4

If you’ve used Camunda BPM you might have noticed our engines briefest feature – it’s really really fast. Might be an idea to have a look at this whitepaper or read about our scalability if you haven’t experienced it for yourself. With the new job prioritization feature and the exponential backoff included in the new Camunda BPM 7.4.0- release you will now be able to improve the speed further by tuning the efficiency of your custom jobs among others. Imagine you have a lot of jobs (maybe 50,000) on a cluster environment which wait to be executed all at the same time. The current behavior of the engine (Camunda BPM 7.3.0) is to acquire all these jobs in parallel and…
