[jira] [Created] (ARROW-16496) [C++] Add roundtrip support to plans + relations

Weston Pace created ARROW-16496:
-----------------------------------

             Summary: [C++] Add roundtrip support to plans + relations
                 Key: ARROW-16496
                 URL: https://issues.apache.org/jira/browse/ARROW-16496
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


Currently we have a significant amount effort put into round tripping expressions and types but we don't yet have support for relations and plans.  Doing so would make it possible to do things like save off Arrow exec plans created by non-substrait means (for example, to save off a plan created by pyarrow or R's current non-substrait dplyr implementation).

It would also help with testing as it would enable more round-trip testing.
