---------------------------------------

             Summary: RecordBuilder UnmarshalJSON does not handle extra unknown fields with complex values
                 Key: ARROW-16471
                 URL: https://issues.apache.org/jira/browse/ARROW-16471
             Project: Apache Arrow
          Issue Type: Bug
          Components: Go
    Affects Versions: 7.0.0
            Reporter: Phillip LeBlanc


The fix for https://issues.apache.org/jira/browse/ARROW-16456 only included support for simple unknown fields with a single value.

i.e.
{code:javascript}
{"region": "NY", "model": "3", "sales": 742.0, "extra": 1234}
{code}
However, nested objects or arrays are still not handled properly.
{code:javascript}
{"region": "NY", "model": "3", "sales": 742.0, "extra_array": [1234], "extra_object": {"nested": ["deeply"]}}
{code}
