> Turns out `arrow-csv` does correctly parse newlines in quoted values, so the issue comes from reading CSVs in parallel. Limiting the target number of partitions to 1 solves the issue. Thank you for the investigation, if that's the case, setting `datafusion.optimizer.repartition_file_scans` to `false` might help: https://datafusion.apache.org/user-guide/configs.html IIRC this option will only limit file scan to one thread, other parts of the plan will still be parallelized using `target_partitions` -- This is an automated message from the Apache Git Service.
