You Don’t Have to Be an Expert: Stories from the Open Source Frontlines
summary
A newcomer with no PyArrow experience four years ago describes concrete wins: a proof of concept at Prague sprints that leads to a PR merged this month folding PyArrow stubs in and enabling autocomplete and type checking, plus adoption of the DataFrame interchange protocol (and alternatives like narwhals) that reduce copying between libraries. Details include Arrow’s C data interface and the arrow py capsule protocol, what each actually does, who implemented what, and which approaches already work versus which remain experimental.
