Mongoose 4.4 now has an insertMany function which lets you validate an array of documents and insert them if valid all with one operation, rather than one for each document:
var arr = [{ name: 'Star Wars' }, { name: 'The Empire Strikes Back' }];
Movies.insertMany(arr, function(error, docs) {});
If I have a very large array, should I batch these? Or is there no limit on the size or array?
For example, I want to create a new document for every Movie, and I have 10,000 movies.
