How To Get Consumer Group Offsets For Partition In Golang Kafka 10

- 1 answer

Now that Golang Kafka library (sarama) is providing consumer group capability without any external library help with kafka 10. How can I get the current message offset being processed by a consumer group at any given time ?

Previously I used kazoo-go (https://github.com/wvanbergen/kazoo-go) to get my consumer group message offset as it is stored in Zookeeper. Now I use sarama-cluster (https://github.com/bsm/sarama-cluster), I am not sure which API to use to get my consumer group message offset.

I am also working with Sarama and Kafka to get offset of a topic.

You can get offset with following code.

    package main

    import (
     "gopkg.in/Shopify/sarama"
     "fmt"
    )

    func main(){
      client , err := sarama.Client([]string{"localhost:9092"},nil) // I am not giving any configuration
      if err != nil {
          panic(err)
      }
      lastoffset, err := client.GetOff := sarama.Client([]string{"localhost:9092"},nil) // I am not giving any configuration
      if err != nil {
          panic(err)
      }
      lastoffset, err := client.GetOffset("topic-test",0,sarama.OffsetNewest)
      if err != nil {
          panic(err)
      }
      fmt.Println("Last Commited Offset ",lastoffset)
    }

Let me know if this is the answer you are looking for and if it is helpful.
