Producer and ConsumerTo run the consumer and producer example, use the following steps:Fork/Clone the repository to your development environment. Install Java JDK 8 or higher. This was tested with Oracle Java 8, but should work under things like OpenJDK as well. Install Mav...
I have created Kafka cluster on a Google Cloud VM Firstly, I tested my broker using cli command to produce message: Producer: $ kafka-console-producer.sh --broker-listlocalhost:9092--producer.config /opt/bitnami/kafka/conf/producer.properties --topic lus_topic >abc Successfully received by th...
把向topic发布消息的客户端称作producer,从topic订阅消息的客户端称作consumer。 producers和consumers可以同时从多个topic读写数据。 一个kafka集群由一个或多个broker服务器组成,它负责持久化和备份具体的kafka消息。 架构.jpg topic:消息存放的目录即主题 producer:生产消息到topic的一方 ...
