Undo feature with Neo4J and Enterprise Java

In this video I'm showing how to implement an undo feature in a Quarkus application that uses a Neo4J database. From a user perspective, an undo action might look little spectacular, but once you know what needs to be taken into account on a database side, it's everything but trivial.

Very nice and interesting approach of an undo-operation in a CDC-like manner.

So you think there is also potential of using Neo4j streams for a distributed system with CQRS / Event Sourcing? Or something like implementing the Outbox Pattern with Neo4j?

And what do you think about splitting the model in a DDD-like manner to business model (POJOs) and to persistence model (OGM annotated classes)?

And do you think this action resource would also be applicable generally in a REST API e.g. POST /coffee/action/order ?

After all my questions, I wish you a merry merry Christmas🌲 and thank you for the nice videos!

Can you show us how to deploy Neo4j + Jupiter notebook on K8s? Thanks a lot!
