package main
import (
"fmt"
"log"
"math/rand"
"strconv"
"time"
"github.com/dgraph-io/badger/v4"
)
var db *badger.DB
const charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
func generateRandomString(length int) string {
b := make([]byte, length)
for i := range b {
b[i] = charset[rand.Intn(len(charset))]
}
return string(b)
}
func main() {
opts := badger.DefaultOptions("badger")
opts.ValueLogFileSize = 1 << 20
var err error
db, err = badger.Open(opts)
if err != nil {
log.Fatal(err)
}
defer db.Close()
fmt.Println("Start inserting 5 million items.")
for i := 0; i < 5_000_000; i++ {
err := db.Update(func(txn *badger.Txn) error {
key := strconv.Itoa(i)
value := []byte(generateRandomString(300))
e := badger.NewEntry([]byte(key), value).WithTTL(30 * time.Second)
err := txn.SetEntry(e)
if err != nil {
return err
}
return nil
})
if err != nil {
log.Fatal("Error while inserting:", err)
}
}
fmt.Println("Successfully inserted 5 million items.")
startGarbageCollection()
}
func startGarbageCollection() {
ticker := time.NewTicker(10 * time.Second)
defer ticker.Stop()
for range ticker.C {
again:
err := db.RunValueLogGC(0.01)
fmt.Println(err)
if err == nil {
goto again
}
}
}
Expected behavior and actual result.
Since the keys are expiring in 30 seconds, I thought that the files in badger/ would get removed.
However, heres what I see:
