<p id="kafka-faq-0043__p31251757201617">Kafka uses the <strong id="kafka-faq-0043__b457617446710">offsets.retention.minutes</strong> parameter to control how long to keep offsets for a consumer group. If offsets are not committed within this period, they will be deleted. If Kafka determines that there are no active consumers in a consumer group (for example, when the consumer group is empty) and there are no offsets, Kafka will delete the consumer group.</p>
