Hi all, After some thought, I thought that we could move forward with this KIP. The low traffic suppression buffer issue is not necessarily a blocker issue, since there are ways to mitigate the problem when implementing this KIP.
Below is the KIP link: https://cwiki.apache.org/confluence/display/KAFKA/KIP-540%3A+Implement+per+key+stream+time+tracking It would be great if I can get some feedback! Cheers, Richard
