             Summary: Allow for array of records to be returned by LookupRecord
                 Key: NIFI-9526
                 URL: https://issues.apache.org/jira/browse/NIFI-9526
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Pierre Villard


In some cases, some lookup services may be able to return multiple records for 
one set of lookup values. It's currently not possible to return all values, we 
return only one (Database lookup, Kudu lookup, Mongo lookup, etc). We should 
provide the option to return an array of records as the result of the lookup.

It may be required to expose a specific property for the controller service to 
allow for multiple records to be returned or not.
