Hi All I would like to call a vote on https://cwiki.apache.org/confluence/display/KAFKA/KIP-213+Support+non-key+joining+in+KTable. This allows a Kafka Streams DSL user to perform KTable to KTable foreign-key joins on their data. I have been using this in production for some time and I have composed a PR that enables this. It is a fairly extensive PR, but I believe it will add considerable value to the Kafka Streams DSL.
The PR can be found here: https://github.com/apache/kafka/pull/5527 See http://mail-archives.apache.org/mod_mbox/kafka-dev/201810.mbox/browser for previous discussion thread. I would also like to give a shout-out to Jan Filipiak who helped me out greatly in this project, and who led the initial work into this problem. Without Jan's help and insight I do not think this would have been possible to get to this point. Adam
