I have three collections, I want to move data from collection A to B filtered by a collection C that is in another database.



Problem is that MongoDb fail, no matter the query I can't move more than 100 document and fail, I think I need an optimized query, I doing this:



db.getSiblingDB('OTHERDATABASE').C.find().forEach(function (d) {

      db.getCollection('A').find({_id:d._id}).forEach(function (x) {

        db.getCollection('B').insert(x);

   })

});
