The warning suppression is correct: it filters by both message= and category=FutureWarning around a single call, and the regexes match the upstream strings in apache/arrow#49590. With filterwarnings = ["error"] in pyproject.toml, this prevents a test failure once CI resolves pyarrow >= 24.0.0.

Two follow-ups, both out of scope here:

1. Pre-existing bug in from_feather: read_table(path, columns, use_threads, memory_map) forwards positionally, but read_table's parameter order is (source, columns, memory_map, use_threads). So use_threads and memory_map are swapped, inverting the documented defaults. Keyword arguments fix it.

2. pyarrow.feather is deprecated; to_feather / from_feather should move to pyarrow.ipc before the API is removed. Note pyarrow.ipc does not compress by default, unlike write_feather.

You can also add this filter in pyproject.toml and avoid modifying tests completely. Smaller change.

Now that @pranjan2023 is working on a proper implementation I don’t think we should spend more time on fixing the temporary fix.
