我们有一个kafka生产者,偶尔会产生一些消息。
我写了一个Consumer来使用这些消息。问题是,仅当其中两个堆栈时,消息才会被使用。例如,如果一条消息是在13:00产生的,则消费者不执行任何操作。如果在13:01产生了另一个消息,则使用者将同时使用这两个消息。在kafkaTool的使用者属性中,存在一个称为LAG的列,当不使用该消息时,该列为1。 我缺少此东西的任何配置吗?
使用者配置:

答案 0 :(得分:0)
弄清楚了。 在kafka 0.9.0.1的文档中,它声明fetch.min.bytes为1。但是我有kafka 0.9.0.0。并且默认值为1024。因此,仅在2条消息之后才传递此值。将fetch.min.bytes更改为1,现在可以正常使用了。
