NIFI-4122 Added the ability to combine multiple Mongo result documents into
a single output JSON array.

> GetMongo should be able to group results into a set of flowfiles

> Key: NIFI-4122
> URL: https://issues.apache.org/jira/browse/NIFI-4122
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Mike Thomsen
> Priority: Minor
> Labels: getmongo, mongodb, nifi
>
> GetMongo should be able to take a user-defined limit and group results by
> that size into flowfiles rather than having only the ability to do a 1:1
> relationship between result and flowfile.
> For example, if the user specifies 100, 100 results should be grouped
> together and turned into a JSON array that can be broken up later as needed.
> This need arose when doing a bulk data ingestion from Mongo. We had shy of
> 400k documents, and the 1:1 generation of flowfiles blew right through our
> limits on the content repository. Adding this feature would make it feasible
> to control that sort of behavior more thoroughly for events like bulk
> ingestion.
