Hi guys, I was reading a paper today in which the latency of kafka and rabbitmq is compared: http://downloads.hindawi.com/journals/js/2015/468047.pdf
To my surprise, kafka has shown some large variations of latency as the number of records per second increases. So I am curious about why is that. Also in the ProducerPerformanceTest: in/kafka-run-class.sh org.apache.kafka.clients.tools.ProducerPerformance test7 50000000 100 -1 *acks=1* bootstrap.servers=esv4-hcl198.grid.linkedin.com:9092 buffer.memory=67108864 batch.size=8196 Setting acks = 1 means the producer will wait for ack from leader replica, right? Could that be the reason which affects latency? If I set it to 0, it will make the producers send as fast as possible therefore the throughput can increase and latency decrease in the test results? Thanks for answering. best,
