How to properly do a Bulk upsert/update in MongoDB

Question

I\'m trying to:

• Find a document according to a search criteria,
• If found, update some attributes
• If not insert a document with some attribut

Answer 1

Typically I have always set upsert as a property on update. Also update should be able to find the record itself so no need to find it individually.

Depending on the environment the $ may or may not be necessary.

batch.update(
 {team: lineUpPointsRoundRecord.teamId, round: 0},
    {      
      $setOnInsert: lineUpPointsGeneralRecord,
      $inc: {lfPoints: roundPoints},
      $push: {roundPoints: roundPoints},
      $upsert: true
    });
