Hi Kafka Users, KTable-KTable Join Semantics is explained in detailed [here][1]. But, it's not clear when the input record is <K:NULL>, some times the output records are generated and in some cases it's not.
It will be helpful, if someone explain on how the output records are generated for all the 3 types of joins on receiving a record with NULL value. [1]: https://cwiki.apache.org/confluence/display/KAFKA/ Kafka+Streams+Join+Semantics#KafkaStreamsJoinSemantics-KTable-KTableJoin -- Kamal
