Remote workers and idempontency

Written by Bernd Rücker on , under Execution category.
In Camunda there is a concept called External Tasks. See External Tasks allows new Use Cases with Camunda BPM or External Tasks in the docs. The basic idea is simple: Camunda does not actively call a service (which would be PUSH), but worker fetch work items queued for them (PULL). Whenever a worker finishes his work item, he reports completion back to Camunda. Workers can use the Java API, but most often leverage the REST API, as this allows to run workers as own process.

Camunda BPM Custom Batch 1.0.0 - New Community Extension

Written by Patrick Schalk on , under Community category.

Have you ever tried to create your own custom batch with Camunda BPM? Well, I did, and it was very time consuming and quite complex. There isn’t really a public API for this purpose. You have to work at the entity level and take care that batch configuration is saved to the ACT_GE_BYTEARRAY database table.

That’s why I’ve decided to create the Camunda BPM Custom Batch Extension.

The goal of this extension is to provide a simple way of using the Camunda Batch functionality for your own purposes.

If you have no clue what Camunda Batch is for, it can be used to split a huge workload (e.g., like reassigning all tasks) into small asynchronous jobs. See the official Camunda docs for more details: Camunda Batch

Written by Patrick Dehn on , under Modeling category.
We are happy to announce the Camunda Modeler version 1.8.2 release!

What’s next? In our current milestone we will focus on reworking text annotations and further improving the usability of the Camunda Modeler.
