我使用Java Producer API将字符串消息发送到Kafka V. 0.8。如果邮件大小约为15 MB,我会收到一个MessageSizeTooLargeException
。我尝试将其设置message.max.bytes
为40 MB,但仍然出现异常。小消息可以正常工作。
(例外出现在生产者中,我在此应用程序中没有消费者。)
我该怎么办才能摆脱这种例外情况?
我的示例生产者配置
private ProducerConfig kafkaConfig() {
Properties props = new Properties();
props.put("metadata.broker.list", BROKERS);
props.put("serializer.class", "kafka.serializer.StringEncoder");
props.put("request.required.acks", "1");
props.put("message.max.bytes", "" + 1024 * 1024 * 40);
return new ProducerConfig(props);
}
