Mongoose bulk update operation

Question

Is there a way to make massive updates to the collection in mongoose? The strategy I found used the source collection driver as follows:

var bulk = Person.collection.initializeOrderedBulkOp();
bulk.find(query).update(update);
...
bulk.execute(callback)

However, it bulkis undefined when I do this. Is it just not supported mongoose?

.

var bulk = Person.collection.initializeOrderedBulkOp();
    bulk.find(query).update(update);
    bulk.execute(function (error) {
       callback();                   
    });

.
$set

var bulk = Person.collection.initializeOrderedBulkOp();
    bulk.find({'_id': {$in: []}}).update({$set: {status: 'active'}});
    bulk.execute(function (error) {
         callback();                   
    });

- id

var bulk = Person.collection.initializeOrderedBulkOp();
    bulk.find({'_id': id}).update({$set: {status: 'inactive'}});
    bulk.execute(function (error) {
         callback();                   
    });

Person.collection.update(
  {'_id': id}, 
  {$set: {status: 'inactive'}}, 
  {multi: true}, 
  callback
)

in {'_id': id} id - , , where, . {$set: {status: 'inactive'}} - , , ": ". {multi: true} , . callback , .
