Hi,
With the release of Apache NiFi 1.2.0 and 1.3.0, the *record* paradigm has
been introduced to better support protocol/format/schema conversion. This moves
away from the `ConvertXToY` type processors in favor of providing custom
*record reader* and *recordset writer* controller service implementations which
can be leveraged and re-used by `LookupRecord`, `ConvertRecord`,
`PartitionRecord`, `QueryRecord`, `MergeRecord`, `UpdateRecord`, etc. There is
already a `JsonTreeReader`, `JsonPathReader`, and `JsonRecordSetWriter`
available, so if you were to provide an `OrcReader` and `OrcRecordSetWriter`,
you would be able to perform bidirectional conversion of JSON to/from Orc,
along with Grok, CSV, Avro, freeform text, and scripted implementations.
