I would like to take a focused slice of this issue: validate `datafusion.execution.parquet.maximum_parallel_row_group_writers` at `SET` time. Zero is currently accepted, but with single-file parallelism enabled it is later passed as the capacity to `tokio::sync::mpsc::channel`, which requires a positive capacity and panics. I plan to reuse the existing `ConfigNonZeroUsize` pattern, update the affected consumers/conversions and generated config documentation, and add a SQLLogicTest showing that zero is rejected. I found no open PR or issue for this specific field. -- This is an automated message from the Apache Git Service.
