concurrent writes and deadlocks #739
Open
Description
Only one read-write transaction is allowed at a time.
From documentation I understand that concurrent writes are not allowed. I'm not sure if this is correct thus this question to clarify: is boltdb designed only for one single writer (globally)? Am I suppose to maintain a lock on any write?
Use case:
I want to store access logs of http requests. Does this mean that I need to use a global channel to serialise the access bolt writes ?
e.g.
var globalChan = make(chan string, 10)
func init() {
const bucketName = "widgets"
tx, err := db.Begin(true)
if err != nil {
panic(err)
}
_, err = tx.CreateBucketIfNotExists([]byte(bucketName))
if err != nil {
return err
}
go func() {
for URL := range globalCHan {
tx, err := db.Begin(true)
if err != nil {
panic(err)
}
bk := tx.Bucket([]byte(bucketName))
// Set the value "bar" for the key "foo".
if err := b.Put([]byte(time.Now().String()), []byte("bar")); err != nil {
return err
}
}
}()
}
func HandleFunc(w http.ResponseWriter, r *http.Request) {
globalChan <- r.URL.String()
}
