I created a Kafka Streams, using quarkus-kafka-stream extension, that uses a persistent store to keep an aggregate and I would like to kwon how to reset the application properly.
Cause of the persisted aggregated, it's not possible to do a clean re-processing of the input logs using only the Kafka Streams Application Reset Tool.
I already read the Confluent documentation and some other posts like this one where people suggest to call KafkaStreams.cleanUp() method or delete the folder /var/lib/kafka-streams/<application.id>, but I think that the situation is a little more tricky with Quarkus.
In my application I wrote the method that produces the topology while the application lifecycle is managed by the plugin so I don't have the reference of the KafkaStreams object on which call the cleanUp() method. Surely I can re-create that object but I'm not sure this is the right way.
Am I missing something? Can someone please clarify to me how it's supposed to be done? If you need further information just ask me.
Thank you
Have a nice day
