el-hult opened a new pull request, #55351: URL: https://github.com/apache/arrow/pull/55351
### Rationale for this change Adresses part of issue #32723. Using the parquet ReadTable functions fails on list of dicts, if they contain more than one row group. In such case, the data is in a chunked array. A NotImplemented guards stops this from being read. ### What changes are included in this PR? This PR is a minimal fix that addresses this in the case when the chunks can be combined into a single array. It does not address the overflow issues, and the preexisting arrow::Concatenate will throw on that. The error is propagated. ### Are these changes tested? One test case is added for this specific situation. It fails without the fix in reader.cc. No regressions on `parquet-arrow-reader-writer-test` found, which I also tested. On macOS. ### Are there any user-facing changes? The users will be able to read a few more parquet files that were previously rejected. ### Was AI used for this PR? Yes. Claude (Opus and Sonnet 5.5) was used for compiling information from existing issues and propose a solution. I decided to do a minimal fix, not addressing the overflow problems, to make sure I understand the PR. I also asked it to verify style guide and contributor process on https://arrow.apache.org/docs/dev/developers/guide/step_by_step/ hoping I dont miss any steps. **PR code and description written by:** - [x] Human (The PR text) - [x] AI (The code) **Reviewed before submission by:** - [x] Human - [ ] AI - [ ] Not reviewed -- This is an automated message from the Apache Git Service.
