Im using insertMany to batchInsert from a CSV. The main problem im getting is that when it fails due to unique index, it does not discriminate (or at least i can find it) from failed ids and actually inserted. There is a list of "insertedIds" but it lists all ids.

Is this a feature or am i doing something wrong?

Is there a workaround?

I have already tried changing the options using

{ordered:false, rawResult: false}

Its actually nothing very fancy, just a simple insertMany, but it will fail (im counting on it) with duplicate index.

 this.insertMany(chunck, {ordered:false, rawResult: false}, ( err, docs ) => {
  if (err) {
    console.log(err.result);
  }
  else {
    console.log(docs);
  }
