WitrynaA producer sends events at a rate of 1,000 events per second, making p 1 MBps. A consumer receives events at a rate of 500 events per second, setting c to 0.5 MBps. With these values, the number of partitions is 4: max (t/p, t/c) = max (2/1, 2/0.5) = max (2, 4) = 4. When measuring throughput, keep these points in mind: Witryna引言 在 Kafka 中，生产者（Producer）负责将消息发送到 Kafka 集群，是实现高效数据流动的关键组件之一。本文将从源码层面分析 Kafka 生产者的实现细节，帮助读者更好地理解 Kaf
