Good day Omair and Anthony. There's a good opportunity to contribute into pyarrow, they need to have the abi3 support to be done before they can include WoA support. This work related to changes in pyarrow itself + perf testing (even with the perf degradation they are fine to have the abi3 anyway).

Could you explore how big is this scope and if it possible to invest our resources into that.
QC partner made this PR but it blocked until abi3. There's some signals from nv as well...

Hi Gleb,

I'll sync with Omair and we can work this out. Where did they ask for it to be completed prior to the merge?

Thanks,
Anthony
