Hi What is the performance impact of setting `max.poll.records=1` as opposed to the default of 500?
I have a Java application which process records one at a time. The processing time varies between messages, so we sometimes exceed the `max.poll.interval.ms`. While I could increase `max.poll.interval.ms` it would prevent me from detecting a livelock in the application quickly. There's no benefit of batching the records so I'm considering setting `max.poll.records=1`. We can define a sensible upper limit for the processing time of a single record. I've tried to look at the code and it seems that it fetches up to ` fetch.max.bytes` and then keep it in-memory and returns records from the fetched data when `poll()` is called. So what is the performance impact of a low `max.poll.records`? Best regards, Mads
