我正在通过flume接收器将事件从flume发送到kafka主题….为此，我使用文件通道，但在写入kafka时性能非常差flume接收器以每秒190 msg的速率写入，而flume源以每秒3000 msg的速率将事件转储到通道….我想增加我的接收器性能…请帮助我如何实现…我尝试了各种配置…这是我的配置文件-----

我认为你的问题是，所有的东西都在一个盒子上运行，所以文件通道的快速接收正在影响kafka，它需要做更多的工作来编写。
我建议两种选择：
将文件通道的容量设置为限制队列大小，这样就不会比kafka接收的速度快。
或者使用Kafka频道：https://flume.apache.org/flumeuserguide.html#kafka-频道。但是，在这个选项中，主题中的消息被 Package 到avroflumeevent中，因此订阅者需要使用该类反序列化。
我也不明白为什么你需要自己的com.flume.test.testjson2kafkasink而不是flume附带的那个。也许你的代码中有一些性能问题。
