> Currently (NiFi 1.4.0) QueryRecord will transfer any attributes from the 
> WriteResult to the outgoing FlowFile, but I don't think there are any (for a 
> query) at the time of this writing. However the QueryRecord processor also 
> updates the "mime.type" attribute based on the RecordSetWriter chosen, and 
> also sets the "record.count" attribute to the number of records that match 
> the query.
> None of the aforementioned are in the processor documentation; if the 
> WriteResult ones are premature to mention that's ok, but we should add the 
> mime.type and record.count attributes to the documentation for QueryRecord.
