Hello all,
First of all thanks for this great project.
I have been investigating and playing with Flowable for the past couple of weeks.
My team is considering a few open source workflow engines to integrate with our case management project and we have been told that these are the decision points.
- Kafka Integration
- Designed for cloud(K8, Microservices, stateless in process)
- **Integration with other commercial ticket management systems(???)**
- OAuth/OIDC, support roles and scopes(keycloak integration)
- **Support of BPEL(???)**
- OpenSource
- Apache 2 License
- UI to define processes(I added ui spring boot starters so I have modeler in my project)
- High Availability
- Listen to system events to change workflow and start activity.
- User can assign other user tasks(task service, setAssignee?)
- **Support of mTLS(???)**
Now, I know a bunch of these are supported-available in Flowable. I added question marks at the end of some points and made them bold that I had trouble to find information about. I was wondering if it is possible for someone to clarify these points.
Thanks

We don’t have any out of the box, but these systems often have a (REST) api, so integrating it is quite easy. Either with service tasks or the (commercial) service registry.

No, we don’t support BPEL. We haven’t seen BPEL for a very long time …

Not sure what this is? Is it related to TLS? If so, it’s an infrastructure question. If it’s possible in Java, it’s possible in Flowable.

Thank you very much @joram.

I was also surprised to see BPEL but since I’m not experienced in workflow engines I needed to ask anyway.

Yes It is related to TLS.
So, assuming I’m not wrong about other points are supported-available-true in Flowable, I think I got my answer.
Thanks again.
