Dear community, I'm creating a proof of concept where I consume messages (JSON) from a kafka topic related to crud operations of a resource. Then, I execute those opperations on a Postgres database. I've uploaded an image describing what I've done. Depending on an "action" field of JSON, I route it to different processor groups that execute those sql statements. My problem is that I need to maintain order, i.e. if I have an update after an insert I need to ensure that insert will be executed before the update. I've played with wait and notify but didn't reach a reasonable solution. Any suggestion? Is nifi the right tool for this kind of problems? Thanks in advance ... View more
