I worked with mongo driver for golang, but possibly that question is actual for other implementations.
Do mongo driver always abort transaction in case errors? Can I prevent implicit abort for transactions?
For example, for such code, I always get err2 = (NoSuchTransaction) Transaction 7 has been aborted. if err1!= nil.
client := ir.Source.Client()
session, err := client.StartSession()
if err != nil {
return err
}
if err := session.StartTransaction(); err != nil {
return err
}
if err = mongo.WithSession(ctx, session, func(sc mongo.SessionContext) error {
_, err1 := ir.Source.Collection(collectionName).UpdateOne(sc,
bson.D{{Key: "_id", Value: bid}},
bson.M{
"$set": bson.D{{Key: "name", Value: "Name"}},
},
)
if err1 != nil {
log.Println(err1) // I don`t want abort here
}
_, err2 = ir.Source.Collection("collectionName").UpdateOne(sc,
bson.D{{Key: "_id", Value: bid}},
bson.M{
"$set": bson.D{{Key: "name", Value: "Name"}},
},
)
if err2 != nil {
log.Println(err2)
sc.AbortTransaction(sc) // i want abort only here
}
return sc.CommitTransaction(sc)
}); err!=nil {
return err
}
Can I use some options for transactions or rewrite code, so I will control transactions abort by myself?
