[jira] [Created] (ARROW-17000) [C++] Relax/implement constraints on field metadata when converting Acero to Substrait

Jeroen van Straten created ARROW-17000:
------------------------------------------

             Summary: [C++] Relax/implement constraints on field metadata when converting Acero to Substrait
                 Key: ARROW-17000
                 URL: https://issues.apache.org/jira/browse/ARROW-17000
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Jeroen van Straten


engine/substrait/type_internal.cc has some already-implemented logic and some TODOs relating to rejecting an Acero plan for conversion to Substrait if field metadata and names are not set to default values, as Substrait does not support these things. ARROW-16988 introduces conversion options that clarify how the converter should behave in cases like these, so once that issue is complete this may be further implemented.
