Description
I tried several ways, including setting CommitInterval, to commit automatically, and didn't commit offset through CommitMessages as expected. Here is my sample code.
package main
import (
"context"
"fmt"
kafka "github.com/segmentio/kafka-go"
)
func main() {
r := kafka.NewReader(kafka.ReaderConfig{
Brokers: []string{"127.0.0.1:9092"},
Topic: "test",
GroupID: "9",
MinBytes: 10e3, // 10KB
MaxBytes: 10e6, // 10MB
})
defer r.Close()
ctx := context.Background()
for {
m, err := r.FetchMessage(ctx)
if err != nil {
break
}
fmt.Printf("message at offset %d：%s\n", m.Offset, string(m.Value))
if shouldCommit(m) {
err = r.CommitMessages(ctx, m)
if err != nil {
fmt.Println("commit failed", err)
}
}
}
}
func shouldCommit(message kafka.Message) bool {
return false
}
