Problem DescriptionWhen processing with Kafka read messages, consumer reads the data in the Afka queue repeatedly. problem ReasonKafka's consumer consumption data will first read a batch of message data from broker to process, and then submit offset after processing. and the consumer consumption in our project is low, resulting in the removal of a batch of data in the session.timeout.ms time without processing completed, automatic submission offset fa
