[jira] [Created] (ARROW-7080) [Python][Parquet] Expose parquet field_id in Schema objects

Ted Gooch created ARROW-7080:
--------------------------------

             Summary: [Python][Parquet] Expose parquet field_id in Schema objects
                 Key: ARROW-7080
                 URL: https://issues.apache.org/jira/browse/ARROW-7080
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Python
            Reporter: Ted Gooch


I'm in the process of adding parquet read support to Iceberg([https://iceberg.apache.org/]), and we use the parquet field_ids as a consistent id when reading a parquet file to create a map between the current schema and the schema of the file being read.  Unless I've missed something, it appears that field_id is not exposed in the python APIs in pyarrow._parquet.ParquetSchema nor is it available in pyarrow.lib.Schema.

Would it be possible to add this to either of those two objects?
