> I have built my own kafka stream joining example from the code：
> https://github.com/confluentinc/learn-kafka-courses/tree/main/kafka-streams/src/main/java/io/confluent/developer/joins，
> the diffenrence is that I use my customed serializer and deserialized without
> schema registry，but it doesn't works，I found out that two streams joining
> will auto create an internal topic ，like
> joining-streams-3-KSTREAM-JOINOTHER-0000000012-store-changelog，but they can't
> deserialize successfully with my own deserializer。
