YannByron opened a new pull request, #9484: URL: https://github.com/apache/paimon/pull/9484
### Purpose Prevent local `BatchTableUpdate.update_by_arrow_batches_with_row_id` calls from silently producing conflicting rewrites when multiple input batches target the same data file. The update now tracks each batch's `first_row_id` file groups, rejects overlap, and aborts files staged by earlier batches. This change is intentionally limited to the local table-update path; distributed Ray updates already coalesce rows by target file. ### Tests - `python3.13 -m pytest -q pypaimon/tests/table_update_test.py pypaimon/tests/table_update_by_row_id_chunked_test.py` - flake8 on the three changed files with `dev/cfg.ini` - `python3.13 -m py_compile` on the three changed files -- This is an automated message from the Apache Git Service.
