Subject KTable-KTable Join Semantics on NULL Key
Date Fri, 08 Sep 2017 11:31:19 GMT
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.
