[GitHub] [arrow] westonpace commented on issue #34410: [Python][C++] No longer possible to specify higher chunksize than the default for Parquet writing

   Ah, I think the problem is that `parquet::arrow::FileWriter::WriteTable` has a `chunk_size` argument (which pyarrow sets) and it also has a `parquet::WriterProperties` which has `max_row_group_length` which pyarrow does not set (and this latter property overrides the former).  So either we need to change pyarrow to set `parquet::WriterProperties::max_chunk_size` or only change the default for `chunk_size` (this might be preferred).
