ilCatania opened a new issue, #48061: URL: https://github.com/apache/arrow/issues/48061
### Describe the bug, including details regarding any error messages, version, and platform. Upgrading to a version of pyarrow from 21 onwards makes the memory footprint of a simple `from pyarrow import dataset` go to more than 1Gb as measured by memray on python 3.11. Version 20 has about 100mb memory footprint for me, with the same import and nothing else. How to reproduce: ```shell uv venv uv pip install 'pyarrow~=21.0' memray memray run -o pyarrow.bin -c 'from pyarrow import dataset' memray flamegraph pyarrow.bin ``` Then open the generated html in your favourite browser ### Component(s) Python -- This is an automated message from the Apache Git Service.
