title: Is there a pymongo (or another Python library) bulk-save?
body: <p>I'm trying to write a function to do a bulk-save to a mongoDB using pymongo, is there a way of doing it? I've already tried using insert and it works for new records but it fails on duplicates. I need the same functionality that you get using save but with a collection of documents (it replaces an already added document with the same _id instead of failing).</p>
  
  <p>Thanks in advance!</p>
