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…

External Tasks allows new Use Cases with Camunda BPM 7.4

In a recent Blog Post I wrote about a concept we call “External Tasks” where services were not actively called from the Workflow Engine (PUSH) but where “Workers” retrieve their tasks from the Workflow Engine (PULL). We discussed this a lot and got so much feedback that we decided to support this pattern out-of-the-box in Camunda BPM 7.4. Let’s have a look at an example (yes – we do have customers implementing video processing :-)): In this case transcoding and uploading a video file can take ages. It is done by special software which often does not have a SOAP or REST API to call. So in this case it is much easier to make an External Task out of…

Escalation Events in Camunda BPM 7.4

The humble escalation event has arrived to the Camunda process engine. Well actually there are technically 6 of them and while each is special in its own little way I’m going to give some examples of the most widely used ones. Escalation events act a lot like error events with one very important difference – You can throw an escalation event without interrupting the process instance. A good example of the usefulness of this event can be seen in the following model: This model describes a situation where someone needs to be made aware of an issue within the process. Specifically where processing is going to take too long, but we also don’t want the process to stop. By using…
