Sure, but you might want to look at the link above your last one as that
touches on the dual ProcessSession you and @markap14 suggested. That turned out
to not be entirely straight-forward, so I hacked on the standard ProcessSession
impl, but I have a feeling my approach could have unintended consequences.
Let me know if you still want to review this now and I'll rebase.
> Make GetMongo support multiple commits and give some progress indication

> 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
