title: MongoDB: BIllions of documents in a collection
body: <p>I need to load 6.6 billion bigrams into a collection but I can't find any information on the best way to do this.</p>
  
  <p>Loading that many documents onto a single primary key index would take forever but as far as I'm aware mongo doesn't support the equivalent of partitioning?</p>
  
  <p>Would sharding help? Should I try and split the data set over many collections and build that logic into my application?</p>
