Subject Re: Trying to understand KafkaConsumer_records_lag_max

Hi Gordon (and list),

Yes, that's probably what's going on. I got another message from 徐骁 which
told me almost the same thing -- something I completely forgot (he also
mentioned auto.offset.reset, which could be forcing Flink to keep reading
from the top of Kafka instead of trying to go back and read older entries).

Now I need to figure out how to make my pipeline consume entries faster (or
at least on par) with the speed those are getting in Kafka -- but that's a
discussion for another email. ;)
