Kafka Producer 终止，1 条消息（881 字节）仍在队列或传输中

Question

我对卡夫卡还很陌生，当我向生产者推送价值时收到此消息

func Produce(topic string, key string, message interface{}) {

    headers := map[string][]byte{
        MSG_HEADER_KEY_CORRELATIONID: []byte("1234"),
        MSG_HEADER_KEY_REQUESTID:     []byte(uuid.NewString()),
        MSG_HEADER_KEY_TESTID:        []byte("456"),
        MSG_HEADER_KEY_MESSAGETYPE:   []byte("TestLookupRequest"),
    }

    kheaders := make([]kafka.Header, 0, len(headers))
    for k, v := range headers {
        kheaders = append(kheaders, kafka.Header{Key: k, Value: v})
    }


    var err error

    servers := "XXXXXX"
    protocol := "SASL_SSL"
    mechanisms := "PLAIN"
    username := "XXXXXXX"
    password := "XXXXXXX"


    Producer, err = kafka.NewProducer(&kafka.ConfigMap{
        "bootstrap.servers": servers,
        "security.protocol": protocol,
        "sasl.username":     username,
        "sasl.password":     password,
        "sasl.mechanism":    mechanisms,
    })

    if err != nil {
        panic(err)
    }
    defer Producer.Close()

    value, _ := json.Marshal(message)

    err = Producer.Produce(&kafka.Message{
        TopicPartition: kafka.TopicPartition{Topic: &topic, Partition: kafka.PartitionAny},
        Key:           []byte("12345"),
        Headers:       kheaders,
        Value:         value,
        Timestamp:     time.Now().UTC(),
        TimestampType: kafka.TimestampCreateTime,
    }, nil)

    if err != nil {
        panic(err)
    }
    Producer.Flush(30)
}

%4|1641074998.615|终止|rdkafka# Producer-1 | [thrd:app]：生产者终止，1条消息（881字节）仍在队列或传输中：使用flush()等待未完成的消息传递

对我如何解决这个问题有任何帮助吗？

请尝试更长的超时时间Flush()；30 毫秒可能还不够。或者尝试使用以下示例中的通道： https: //github.com/confluenceinc/confluence-kafka-go/blob/80c58f81b6cc32d3ed046609bf660a41a061b23d/examples/ Producer_example/ Producer_example.go
