How can I execute a callback after a massive multiple insert with Mongoose?

I have an object 开发者_运维问答results that's very large (maybe over 1,000 items). I'm iterating over it to save to the DB but this seems very inefficient:

        for result in results
          item = new Item result
          item.save()

Is there a more optimal way to do this and THEN get a callback as opposed to a callback for EVERY save?

The async module will help a lot with this. You're probably looking for a queue.

You may be getting near the edge of a the normal Node.js use case.
