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

             Summary: [C++] Add support for custom output field names in a substrait::PlanRel
                 Key: ARROW-15592
                 URL: https://issues.apache.org/jira/browse/ARROW-15592
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


A Substrait plan consists of multiple relations.  Some (only one?) of those relations can be "root" relations which means they name the output fields.  We currently do not support this.  It should be a straightforward projection to assign the field names.
