2.1 Producer API We encourage all new development to use the new Java producer. This client is production tested and generally both faster and more fully featured than the previous Scala client. You can use this client by adding a dependency on the c…

转自:http://www.cnblogs.com/f1194361820/p/6048429.html 通过前面的架构简述,知道了Producer是用来产生消息记录,并将消息以异步的方式发送给指定的topic的某个partition的.另外还知道,它保证了消息的有序的发送.那么它是如何做到这些的呢?我们又该如何使用它的API来发送消息? Kafka Producer.Kafka Consumer相对于 Kafka Broker,都属于客户端.Kafka支持多种语言的客户端.下面就根据Java…

升级Kafka集群的版本其实很简单,核心步骤只需要4步,但是我们需要在升级的过程中确保每一步操作都不会“打扰”到producer和consumer的正常运转.为此,笔者在本机搭了一个测试环境进行实际的版本升级实验.在开始之前,简要介绍一下测试环境的部署情况及目标:Kafka 0.10.0.0 双broker测试环境,而目标是把该集群升级到0.10.2版本 两个broker启动时分别读取server.properties和server2.properties. 一.启动测试环境打开两个终端,分别执…

前面写了关于kafka和spark streaming的结合使用(https://www.cnblogs.com/qfxydtk/p/11662591.html),其具体使用用法其实来自于原文:http://spark.apache.org/docs/2.2.0/streaming-kafka-integration.html 在前文的参考文献中也列举出了此地址,但是在使用时,spark-streaming-kafka-0-8是稳定版,spark-streaming-kafka-0-10是实验版…
