Vincent-Philippe Lauzon points out a few limitations with Cosmos DB:

The original DocumentDB SQL didn’t have any aggregation capacity.  But it did acquire those capacities along the way.

Traditionally, that isn’t the strong spot for document-oriented databases.  They tend to be more about find documents and manipulating the documents as oppose to aggregating metrics on a mass of documents.

  • SUM

  • MIN

  • MAX

  • AVG
