Removed the
IdempotenceHandlerlayer in the event consumer -- it was too difficult to plug all possible gaps. There's nothing more to be done in the core, it seems.During offline discussions we talked about the scenario where a file is registered, then deleted, and then the Kafka events are replayed so the registration event (FileUploadValidationSuccess) is consumed again. This scenario should actually not happen because the event re-publish mechanism would publish the latest state of the object in the FIS. Topic compaction should also be used though if it's not already.
