发送和消费

## 生产者

增加副本

  1. 创建规则json

    cat > increase-replication-factor.json <<EOF
    {"version":1, "partitions":[
    {"topic":"__consumer_offsets","partition":0,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":1,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":2,"replicas":[0,1]},

    {"topic":"__consumer_offsets","partition":23,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":24,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":25,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":26,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":27,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":28,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":29,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":30,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":31,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":32,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":33,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":34,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":35,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":36,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":37,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":38,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":39,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":40,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":41,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":42,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":43,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":44,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":45,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":46,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":47,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":48,"replicas":[0,1]},
    {"topic":"__consumer_offsets","partition":49,"replicas":[0,1]}]
    }
    EOF
    
  2. 执行

    bin/kafka-reassign-partitions.sh --zookeeper localhost:2181 --reassignment-json-file increase-replication-factor.json --execute
    
  3. 验证

    bin/kafka-reassign-partitions.sh --zookeeper localhost:2181 --reassignment-json-file increase-replication-factor.json --verify

  • 您好,有没有用Java API创建,查找topic的文章?
    • 做的是一个先查询,如果没有这个topic,则去创建topic。
      我用网上查找的TopicCommand.main(options);报错运行不出来。。。
        我这kafka内存占用率下不来,什么情况,消息也过了失效的时间。
        • 咦,我记得回答过你的问题。
          kafka是基于jvm的,充分利用当前内存,当有别的进程启动的时候,会释放这部分内存。
            .sh在命令台运行不了啊,不是只能运行.bat文件吗
            请教一下,我使用的是2.11版本的kafka,在Susue系统上使用命令创建生产者和消费者进行测试,我都是直接ctrl+C直接退出生产者/消费者的窗口,但ps进程的时候发现生产者和消费者的进程是依然存在的...而且ps -ef|grep java | grep kafka 出来的内容没有办法区分这个进程是生产还是消费者,甚至是否为broker也无法区分..有什么办法可以不使用生产/消费者的时候就直接kill 进程呢?
            并且 kafka-server-stop.sh 以及zookeeper-server-stop.sh 脚本并没有什么用处......
            • jps倒是可以..但是应该也不能区分到底是哪个进程吧。zookeeper可以区分,但是broker和consumer,producer貌似没法区分~~~~感谢你的所有文章以及回复。
                我的mac运行消费者命令时候一直显示kafka-console-producer.sh:commend not found,请问是咋回事,拜谢!
                我想在shell里面调kafka的rest api,不知道是否可行?
                大神,能否推荐一个高并发性能的rest api方案?只使用该rest api生产消息
                大神,问个问题:
                我要做一个监控系统,包含大量的shell监控脚本,每个脚本负责各自的监控任务。大量脚本并发执行,我想使用kafka作为脚本的缓存。遇到的问题是kafka没有专门针对shell的client,调用Java client性能很不理想。大神有没有什么好的办法解决呢?
                归结为一句话就是:如何在多个并发的shell里使用kafka生产消息,请大神指点一二,谢谢~
