>             Project: Apache NiFi
>          Issue Type: Improvement
>            Reporter: Mike Thomsen
>            Assignee: Mike Thomsen
>            Priority: Major
> It shouldn't wait until the end to do a commit() call because the effect is 
> that GetMongo looks like it has hung to a user who is pulling a very large 
> data set.
> It should also have an option for running a count query to get the current 
> approximate count of documents that would match the query and append an 
> attribute that indicates where a flowfile stands in the total result count. 
> Ex:
> query.progress.point.start = 2500
> query.progress.point.end = 5000
> query.count.estimate = 17,568,231
