Hi, in some topics of our system, the data volumn is so huge that we think doing extra replica is a waste of disk and network resource( plus the data is not so important).
firstly, we use 1 replica + ack=0, found when 1 broker is down, the data would loss 1/n. then we tried 1 replica + ack=1, and found after 3 tries, the data is still lost. and when we set the try number large enough, no more data can be produced to Kafka. If I did not misunderstand, In 0.7, when 1 broker is down, both producing and consuming are available with no data loss. I can see the reason why kafka 0.8 is designed to be different like 0.7. but is there a way to let producer of 0.8 act like the behavior in 0.7? We don't care which part of data should go to the specific partition, as long as the data goes into the kafka with no loss. Thanks -- *Best RegardsXiang Helin*
