Another thing I find exciting about Spring Modulith is its Event Publication Registry. Seems like it has the potential to replace "Kafka + Outbox" in many use cases (e.g. when sending a user-verification-mail with eventual consistency, or when you'd want to avoid long running transactions and prefer asynchronous events with eventual consistency), thus getting rid of the Kafka complexity!

Hi Blue! Long since I worked on this, but AFAIK, at least there's a state attribute to differentiate among different requests.

Very helpful! Two questions:

1) Is BPMN a natural fir for the Orchestration? Is it a common practice or there's any downside?

2) What could be the solutions to ensure that Orchestration service updates the state and then publishes the event in a single transaction? (I.e. after the stare is updated, publshing the event might fail, or vice versa)

Thanks Srikanth. Spring Lemon has the code for Bpring Boot and AngularJS (but not Angular 6)
