Wes McKinney commented on ARROW-7080:
-------------------------------------
This ended up being a slight can of worms to handle properly. I'm going to put
up a PR shortly
> [Python][Parquet][C++] 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: C++, Python
> Reporter: Ted Gooch
> Assignee: Wes McKinney
> Priority: Major
> Labels: parquet
> Fix For: 1.0.0
>
>
> 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?
