+including both dev and user mailing lists. Hi, Thanks for the KIP.
"* For us, the message keys represent some metadata which we use to either ignore messages (if a loop-back to the sender), or log some information.*" Above statement was mentioned in the KIP about how key value is used. I guess the topic is not configured to be compacted and you do not want to have partitioning based on that key. IMHO, it qualifies more as a header than a key. What do you think about building records with a specific header and consumers to execute the logic whether to process or ignore the messages based on that header value. Thanks, Satish.
