> 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
