asfimport opened a new issue, #29862: URL: https://github.com/apache/arrow/issues/29862
Subtask for ARROW-14196. Currently, if you have a list column, where the list elements itself are nested items (eg a list of structs), selecting a subset of that list column requires something like `columns=["columnA.list.item.subfield"]`. While this "list.item" is superfluous, since a list always contains a single child. So ideally we allow to specify this as `columns=["columnA.subfield"]`. This also avoids relying on the exact name of the list item (item vs element), for which the default differs between Parquet and Arrow. **Reporter**: [Joris Van den Bossche](https://issues.apache.org/jira/browse/ARROW-14286) / @jorisvandenbossche #### Related issues: - [[C++][Parquet] Default to compliant nested types in Parquet writer](https://github.com/apache/arrow/issues/29781) (is related to) #### PRs and other links: - [GitHub Pull Request #11385](https://github.com/apache/arrow/pull/11385) <sub>**Note**: *This issue was originally created as [ARROW-14286](https://issues.apache.org/jira/browse/ARROW-14286).
