[jira] [Created] (ARROW-14196) [C++][Parquet] Default to compliant nested types in Parquet writer

Joris Van den Bossche created ARROW-14196:
---------------------------------------------

             Summary: [C++][Parquet] Default to compliant nested types in Parquet writer
                 Key: ARROW-14196
                 URL: https://issues.apache.org/jira/browse/ARROW-14196
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++, Parquet
            Reporter: Joris Van den Bossche


In C++ there is already an option to get the "compliant_nested_types" (to have the list columns follow the Parquet specification), and ARROW-11497 exposed this option in Python.

This is still set to False by default, but in the source it says "TODO: At some point we should flip this.", and in ARROW-11497 there was also some discussion about what it would take to change the default.
