             Summary: Improve handling of embedded JSON records
                 Key: NIFI-12480
                 URL: https://issues.apache.org/jira/browse/NIFI-12480
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Core Framework, Extensions
            Reporter: Mark Payne
            Assignee: Mark Payne


It proves to be difficult to treat embedded JSON elements as Strings. There are times when this is necessary, such as when pushing to a database that declares a field of type JSON or interacting with a web service that expects incoming JSON as a String. However, there's no easy way to do this in NiFi today.

Instead, what typically happens is that the Record gets converted to a String via a call to {{toString()}} and that produces something like {{{}MapRecord[name=John Doe, color=blue]{}}}, which is not helpful.

However, when a JSON Reader is used, we already have a JSON representation of the Record in the record's SerializedForm. When {{toString()}} is called, we should always use the SerializedForm of a Record, if it is available and only fall back to the given version.
