Typo: after each flowfile is *written.*
> Make GetMongo support multiple commits and give some progress indication

> Key: NIFI-4838
> URL: https://issues.apache.org/jira/browse/NIFI-4838
> 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
