Hi, just for the record in this RFP and to move this a bit into the spotlight: I have moved my packaging repository for Apache Arrow to the Debian Science project in Salsa [1]. See the corresponding thread in the Debian Med mailing list for more context [2].
TLDR: I have prepared a package to cover as much of Arrow as is possible with what we have in Debian, dependency-wise. There is still a review of d/copyright missing, and some bundled code might need some extra love or removal. If someone wants to work on this and wants to maintain it for longer, feel free to let me know and I might help get it finished. :) I just feel I won't be able to keep this updated in time on my own given how busy upstream seems to be.
