This is a new processor that uses the JSON query DSL via the low level client. The motivation was to make it possible to write a query in Kibana, including aggregations, and be able to run it directly from NiFi. As far as I know, none of the existing processors support the aggregation system. If someone could take a look and review, that'd be appreciated. Thanks, Mike
