Hi, I’ve been (together with the PyPy team) working on getting arrow to build on PyPy3. I’m not looking for full feature capability, but specifically getting it to work with pandas read_parquet/to_parquet which it now does. There were a few roadblocks solved by the awesome Matti Picus on the PyPy Team and we now have a patch that successful builds pyarrow on PyPy3. PyPy3 side has already been patched.
The patch for pyarrow is on https://gist.githubusercontent.com/mattip/c9c8398b58721ae5893dc8134c353f28/raw/0daff3e11ceed6dcde485a56e6b8bd2b7ca48bbc/gistfile1.txt A Dockerfile which builds everything is available on https://github.com/bivald/pyarrow-on-pypy3/blob/feature/latest-pypy-latest-pyarrow/Dockerfile (https://github.com/bivald/pyarrow-on-pypy3/tree/feature/latest-pypy-latest-pyarrow) A surprisingly amount of tests passes (such as all the parquet tests when I tested it last) but some other areas segfaults, but neither of them is super important for me right now. Would the arrow project be open to a PR with the above patch, even though it doesn’t give you full PyPy support? Regards, Niklas
