> Shouldn't the missing bindings reported earlier in [https://github.com/apache/arrow/pull/11632] be propagated higher up [here in the parquet.py module|https://github.com/apache/arrow/blob/master/python/pyarrow/parquet.py#L2217]?
> Passing **kwargs as is the case for {{write_table}} would do the trick I think.
> I am finding myself stuck while using pandas.to_parquet with {{use_legacy_dataset=false}} and no way to set the {{existing_data_behavior}} flag to {{overwrite_or_ignore}}
