我正在尝试将kafka的默认消息大小从1mb增加到10mb。我正在用embeddedkafka和scalatest测试我的新配置,但它不起作用。
使用这个答案,我相应地增加了配置值:
经纪人:
message.max.bytes replica.fetch.max.bytes
消费者: max.partition.fetch.bytes
制作人: max.request.size
我的代码:
val broker = s"localhost:${kafkaConfig.kafkaPort}"
val maxSize: String = (ConsumerConfig.DEFAULT_MAX_PARTITION_FETCH_BYTES * 10).toString // 10MiB
val embeddedBrokerConfig = Map(
"message.max.bytes" -> maxSize,
"replica.fetch.max.bytes" -> maxSize
)
val embeddedConsumerConfig = Map[String, String](
ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG -> broker,
ConsumerConfig.GROUP_ID_CONFIG -> consumerGroup,
ConsumerConfig.AUTO_OFFSET_RESET_CONFIG -> "earliest",
ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG -> "false",
ConsumerConfig.MAX_PARTITION_FETCH_BYTES_CONFIG -> maxSize
)
val embeddedProducerConfig = Map[String, String](
ProducerConfig.BOOTSTRAP_SERVERS_CONFIG -> broker,
ProducerConfig.MAX_REQUEST_SIZE_CONFIG -> maxSize
)
val bigKafkaConfig =
EmbeddedKafkaConfig(
kafkaConfig.kafkaPort,
kafkaConfig.zooKeeperPort,
customBrokerProperties = embeddedBrokerConfig,
customConsumerProperties = embeddedConsumerConfig,
customProducerProperties = embeddedProducerConfig
)
val bigMessage = ("H" * 999999).getBytes()
EmbeddedKafka.publishToKafka(inTopic, bigMessage)(bigKafkaConfig, valueSerializer)
当我用一个只有999999字节(低于1mb)的消息运行此代码时,我得到以下错误:
Caused by: java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.RecordTooLargeException: The request included a message larger than the max message size the server will accept.

这是嵌入Kafka中的一个bug吗?还是我的应用程序配置错误?

我发现了问题所在。这是由于
EmbeddedKafka
.有一个
beforeAll
在使用默认配置进行测试之前启动embeddedkafka的语句。EmbeddedKafka.start
需要更新的代理设置,并在EmbeddedKafka
已经开始什么都不做了。
