Hi all, I'd like to start a discussion for the KIP-931: Flag to ignore unused message attribute field. This KIP is to add a flag in the batch header to indicate if messages inside the batch have attribute field or not, to reduce the message size, thus, save network traffic and storage size (and money, of course).
Please check the link for more detail: https://cwiki.apache.org/confluence/display/KAFKA/KIP-931%3A+Flag+to+ignore+unused+message+attribute+field Any feedback is welcome. Thank you. Luke
