kafka流不提取所有记录

我有一个java Kafka流应用程序，它从一个主题中读取一些过滤和转换，并将数据写回Kafka到另一个主题 . 我在每一步都打印流对象 . 我注意到如果我向输入主题发送了超过几十条记录，我的Kafka流应用程序会消耗一些记录 not .

当使用kafka-console-consumer.sh从输入主题中消费时，我确实收到了所有记录 .

我正在使用一个代理和一个分区主题运行Kafka 1.0.0 .

知道为什么吗？

public static void main(String[] args) {
    final String bootstrapServers = System.getenv("KAFKA");
    final String inputTopic = System.getenv("INPUT_TOPIC");
    final String outputTopic = System.getenv("OUTPUT_TOPIC");
    final String gatewayTopic = System.getenv("GATEWAY_TOPIC");
    final Properties streamsConfiguration = new Properties();
    streamsConfiguration.put(StreamsConfig.APPLICATION_ID_CONFIG, "PreProcess");
    streamsConfiguration.put(StreamsConfig.CLIENT_ID_CONFIG, "PreProcess-client");
    streamsConfiguration.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
    streamsConfiguration.put(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName());
    streamsConfiguration.put(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName());
    streamsConfiguration.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
    streamsConfiguration.put(StreamsConfig.COMMIT_INTERVAL_MS_CONFIG, 300L);


    final StreamsBuilder builder = new StreamsBuilder();
    final KStream<String, String> textLines = builder.stream(inputTopic);
    textLines.print();
    StreamsTransformation streamsTransformation = new StreamsTransformation(builder);
    KTable<String,Gateway> gatewayKTable = builder.table(gatewayTopic, Consumed.with(Serdes.String(), SerdesUtils.getGatewaySerde()));
        KStream<String, Message> gatewayIdMessageKStream = streamsTransformation.getStringMessageKStream(textLines,gatewayKTable);
    gatewayIdMessageKStream.print();
    KStream<String, FlatSensor> keyFlatSensorKStream = streamsTransformation.transformToKeyFlatSensorKStream(gatewayIdMessageKStream);
    keyFlatSensorKStream.to(outputTopic, Produced.with(Serdes.String(), SerdesUtils.getFlatSensorSerde()));
    keyFlatSensorKStream.print();

    KafkaStreams streams = new KafkaStreams(builder.build(), streamsConfiguration);
    streams.cleanUp();
    streams.start();
    // Add shutdown hook to respond to SIGTERM and gracefully close Kafka Streams
    Runtime.getRuntime().addShutdownHook(new Thread(() -> {
        streams.close();
    }));
