The MongoDB Reader node reads documents from a MongoDB database and returns them as JSON cells in a table. The node uses Jongo to retrieve the documents and therefore the query, projection and sorting notation is the same as described in the Jongo documentation and very close to how querying is done in the MongoDB shell.
