The JS API has a count() method on the cursor*, to return the count of matching objects in the collection even when you have a limit/skip associated with the find. This is very useful to not have to spawn separate Count operations in parallel with finds. |

Hi gpean, What is implemented by the Node driver isn't any more efficient than doing a count on it's own, and the same is true of the Go driver. Additionally, not all cursors have a count associated with them. For instance, ChangeStreams return a Cursor but there is no way to count the number of documents ahead of time returned by a ChangeStream. Thanks, Kris |
