本篇内容介绍了"Kafka2.7是如何重设消费者组位移"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

重设消费

Earliest

首先看看重置位移前的消费进度

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --describe

根据进度截图，能看到所有分区的Lag均为0，说明消息已经被消费完，现在根据Earliest策略重置消费进度，要求重置后所有的消息均可重新消费。

脚本命令方式

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic --to-earliest --execute

此时再度查看消费进度，可以看到此时消费者可以重新消费这些消息。

脚本命令方式(指定分区)

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic:1,2 --to-earliest --execute

Java API方式

Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "192.168.1.108:9092");
props.put(ConsumerConfig.GROUP_ID_CONFIG, "mytopic-consumer-group");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());

final String topic = "mytopic";
try (KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    Collection partitions = consumer.partitionsFor(topic).stream()
            .map(partitionInfo -> new TopicPartition(topic, partitionInfo.partition()))
            .collect(Collectors.toList());
    consumer.seekToBeginning(partitions);
    consumer.partitionsFor(topic).forEach(i -> consumer.position(new TopicPartition(topic, i.partition())));
}

需要特殊说明的是，seekToBeginning、seekToEnd等方法执行完需要执行position才会立刻生效

Java API方式(指定分区)

Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "192.168.1.108:9092");
props.put(ConsumerConfig.GROUP_ID_CONFIG, "mytopic-consumer-group");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());

final String topic = "mytopic";
try (KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    List partitions = new ArrayList();
    partitions.add(new TopicPartition(topic, 1));
    partitions.add(new TopicPartition(topic, 2));
    consumer.seekToBeginning(partitions);
    consumer.position(new TopicPartition(topic, 1));
    consumer.position(new TopicPartition(topic, 2));
}

Latest

首先看看重置位移前的消费进度。

根据上图可以看到，kafka当前没有任何消息被消费，现在根据Latest策略重置消费进度，要求重置后原消息不再消费。

脚本命令

props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.GROUP_ID_CONFIG, "mytopic-consumer-group");

final String topic = "mytopic";
try (final KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    consumer.seekToEnd(consumer.partitionsFor(topic).stream()
            .map(partitionInfo -> new TopicPartition(topic, partitionInfo.partition()))
            .collect(Collectors.toList()));
    consumer.partitionsFor(topic).forEach(i -> consumer.position(new TopicPartition(topic, i.partition())));
}

props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.GROUP_ID_CONFIG, "mytopic-consumer-group");

final String topic = "mytopic";
try (final KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    List partitions = new ArrayList();
    partitions.add(new TopicPartition(topic, 1));

Current

此方法暂时联想不到相应的应用场景，粗略跳过，待以后了解后再补充。

脚本命令

脚本命令(指定分区)

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic:1,2 --to-current --execute

Java API

final String topic = "mytopic";
try (final KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    consumer.partitionsFor(topic).stream().map(info -> new TopicPartition(topic, info.partition())).forEach(tp -> {

Specified-Offset

重置前

脚本命令

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic --to-offset 5 --execute

脚本命令(指定分区)

通常来说，各个分区的提交位移往往是不同的，所以将所有分区的位移设置成同一个值并不显示，需要指定分区。

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic:2 --to-offset 11 --execute

props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.GROUP_ID_CONFIG, "mytopic-consumer-group");

final String topic = "mytopic";
try (final KafkaConsumer consumer = new KafkaConsumer<>(props)) {
    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    consumer.partitionsFor(topic).stream().forEach(pi -> {
        TopicPartition tp = new TopicPartition(topic, pi.partition());
        consumer.seek(tp, 5L);
    });

    consumer.subscribe(Arrays.asList(topic));
    consumer.poll(0);
    consumer.seek(new TopicPartition(topic, 2), 10L);

DateTime

有时按照时间点来重置位移是个不错的方式，重置前:

Duration

重置前

脚本命令

首先需要了解Java Duration的格式PnDTnHnMnS，这里不做详细展开。

bin/kafka-consumer-groups.sh --bootstrap-server 192.168.1.108:9092 --group mytopic-consumer-group --reset-offsets --topic mytopic --by-duration P1DT0H0M0S --execute
