Hi guys, Version: Kafka_2.11-1.10 my Kafka consumer offset was disappeared, in ‘__consumer_offset’, that topic’s message is empty. the consumer hasn’t commit at least 15 days, i think the configuration ‘offsets.retention.minutes’ effects i want to test this, i set offsets.retention.minutes=5 in server.properties, restart kafka, create topic, send data, create consumer… but 1.5 hours later, it's still not disappear(i don’t send data again in 1.5 hours)… i’m very confused, i just want to know what makes the offset disappear Thanks, Wei
