卡夫卡消费者抵消出口黄金-夏尔马或合流-卡夫卡-围棋自由
提问于 2022-04-29 13:45:32
我正试图找到一种对消费者群体执行抵消重置操作的方法，例如在Kafka命令中是这样的：
kafka-consumer-groups.sh --bootstrap-server $kfk --dry-run --reset-offsets --topic $t --group $cg1 --to-current --export | tee topic-offset.csvkafka-consumer-groups.sh --bootstrap-server $kfk --dry-run --reset-offsets --topic $t --group $cg2 --to-current然后根据导出文件导入新的偏移量？
kafka-consumer-groups.sh --bootstrap-server $kfk --execute --reset-offsets --topic $t --group $cg2 --from-file topic-offset.csv从文件导出的导入不是问题.只是找不到办法得到然后设置偏移量..。
那么，是否有人使用sharma或confluent-kafka-go库来玩这个呢？
(谢谢你事先提出的建议:)

下面是一些简单的up，它在YMAL配置的基础上进行偏移复位
https://github.com/nXnUs25/kfk-offsets
用于滞后监视使用者组列表和偏移重置的命令行工具。
我们有相同的抵消…现在，为了模拟这个过程，我们将生成主题消息，并继续使用其中一个消费者组propertest-cg1a11，我们将生成5条消息并在该消费者组中使用它们，这将给我们提供我们所消费的信息。

好的，我想我发现它只是需要实现完整的解决方案，但是我应该对
func main() {
brokers := []string{BK}
kfk.Logger = log.New(os.Stdout, "", log.LstdFlags)
cfg := kfk.NewConfig()
cfg.ClientID = CID
client, _ := kfk.NewClient(brokers, cfg)
//fmt.Println(client)
offsetMg, _ := kfk.NewOffsetManagerFromClient(CG, client)
defer offsetMg.Close()
consumer, _ := kfk.NewConsumerFromClient(client)
defer consumer.Close()
partitions, _ := consumer.Partitions(TOPIC)
for _, p := range partitions {
pom, _ := offsetMg.ManagePartition(TOPIC, p)
ofs, pomStr := pom.NextOffset()
fmt.Printf("Partition: %v -> nextOffset: %v:%s\n", p, ofs, pomStr)
}
fmt.Println("--")
}这给了我这个输出：
Partition: 0 -> nextOffset: 31:
Partition: 1 -> nextOffset: 30:
Partition: 2 -> nextOffset: 45:
Partition: 3 -> nextOffset: 39:
Partition: 4 -> nextOffset: 45:
Partition: 5 -> nextOffset: 39:
Partition: 6 -> nextOffset: 37:
Partition: 7 -> nextOffset: 42:
Partition: 8 -> nextOffset: 43:
Partition: 9 -> nextOffset: 35:
Partition: 10 -> nextOffset: 41:
Partition: 11 -> nextOffset: 36:它与from java命令完全相同：
❯ kafka-consumer-groups.sh --bootstrap-server $kfk --dry-run --reset-offsets --topic $t --group $cg1 --to-current | sort -k3 -n
GROUP TOPIC PARTITION NEW-OFFSET
propertest-cg1 propertest 0 31
propertest-cg1 propertest 1 30
propertest-cg1 propertest 2 45
propertest-cg1 propertest 3 39
propertest-cg1 propertest 4 45
propertest-cg1 propertest 5 39
propertest-cg1 propertest 6 37
propertest-cg1 propertest 7 42
propertest-cg1 propertest 8 43
propertest-cg1 propertest 9 35
propertest-cg1 propertest 10 41
propertest-cg1 propertest 11 36所以现在只剩下把这些数据导出到一个文件并使用函数。
// ResetOffset resets to the provided offset, alongside a metadata string that
// represents the state of the partition consumer at that point in time. Reset
// acts as a counterpart to MarkOffset, the difference being that it allows to
// reset an offset to an earlier or smaller value, where MarkOffset only
// allows incrementing the offset. cf MarkOffset for more details.
ResetOffset(topic string, partition int32, offset int64, metadata string)设置新的偏移..。
