Support e.g. modern MacBooks running Linux containers
Modern MacBooks have aarch64 CPUs. When using containers (or virtualized Linux in general), they now have to build Pandas from source if installing from the PyPI index. This costs a lot of time and complexity that is better dealt with in the Pandas product build environment.

Yes, many container images including ours are based on Alpine Linux, which is the main 'container distro'. It is based on musl libc. Generally we generate wheels for platforms we have CI testing for, and currently we don't test on musl aarch. Once testing is added, we'd probably be more comfortable releasing wheels for it since there would be "support" I'll gladly implement testing. Any pointers? > I'll gladly implement testing. Any pointers?

I would suggest trying to modify `unit-tests.yml` and copy the job contents of the `Linux-Musl` job except to use this image: https://quay.io/repository/pypa/musllinux_1_2_aarch64 This pull request is stale because it has been open for thirty days with no activity. Please [update](https://pandas.pydata.org/pandas-docs/stable/development/contributing.html#updating-your-pull-request) and respond to this comment if you're still interested in working on this. I'm going to close this PR, but I merged in another PR a while back adding arm64 musllinux wheels (which you can expect to see in the next release).
