> There still seems to be a lot of confusion about the design of the poll() loop in regard to consumer liveness. We do mention it in the javadoc, but it's a little hidden and we aren't very clear on what the user should do to limit the potential for the consumer to fall out of the group (such as tweaking max.poll.records). We should pull this into a separate section (e.g. Jay suggests "Detecting Consumer Failures") and give it a more complete treatment.
