I haven’t got a concrete example, but I’ll try to answer this for everyone coming from the Camunda BPM angle.
At this point in time, Zeebe is like Camunda BPM when
- You restrict yourself to plain standard-compliant BPMN XML (further narrowed down by Zeebe’s supported BPMN elements)
- Plus external tasks
- Plus input/output mappings
- And nothing more
On top of that, Zeebe is designed to handle very high workloads and to scale well, and outperforms Camunda BPM in this regard.
So coming back to use cases, you can implement any use case with Zeebe that you would implement with Camunda BPM under the above constraints. It makes particularly sense, when you have workloads that require Zeebe’s performance.
