no `transform()` because keying must be preserved -- if you want to change the keying you  need to use `KTable#groupBy()` (data needs to be repartitioned if you change the key). HTH. -Matthias On 1/12/24 11:47 AM, Igor Maznitsa wrote: Hello Is there any way in Kafka Streams API to define p

Hello Is there any way in Kafka Streams API to define processors for KTable and KGroupedStream like KStream#transform? How to provide a custom processor for KTable or KGroupedStream which could for instance provide way to not downstream selected events? -- Igor Maznitsa email: rrg4

Hello If I have started two KafkaStream application instances, and they have parameter 'num.standby.replicas=1'. It means that each instance has shadow copy of local state stores, so the question: How InteractionQuery behaves in activated stand by replica case? does it aware about replicated
