batterseapower opened a new issue, #39093: URL: https://github.com/apache/arrow/issues/39093
### Describe the bug, including details regarding any error messages, version, and platform. `pandas_compat.py' calls `pd.is_sparse` (https://github.com/apache/arrow/blob/1cc1f4c752895301371ee59d315ebffe74224c66/python/pyarrow/pandas_compat.py#L374). With Pandas 2.1, this API is deprecated, so any attempt to e.g. use `DataFrame.to_parquet` prints this warning: ``` pyarrow/pandas_compat.py:373: FutureWarning: is_sparse is deprecated and will be removed in a future version. Check `isinstance(dtype, pd.SparseDtype)` instead. ``` A similar bug was flagged in #35329 but the corresponding PR #35366 only removed one use of the function. `pandas_compat.py` is still an issue. (Link to the pandas issue: https://github.com/pandas-dev/pandas/issues/52899 where this is also being discussed.) ### Component(s) Python -- This is an automated message from the Apache Git Service.
