Hi, I am getting this exception Exception in thread "main" org.apache.kafka.streams.errors.TopologyBuilderException: Invalid topology building: KTABLE-MAPVALUES-0000000007 and KSTREAM-AGGREGATE-0000000009 are not joinable
What I am trying to do is I aggregate a KStream into a KTable of type KTable<String, Map<String, List<V>>> and I am trying to join it to another KStream which is aggregated into another KTable of type KTable<String, List<V>> Since keys of both the final KTable are same, I don't understand why it is giving this exception. Thanks Sachin
