attrs looks interesting, can it be used in workflows for processing GBs of data? I don't see any Cython compatibility or other Python to compiled code options. I typically just get by with numpy recarrays, but I'm old fashioned and looking for something more modern.

Attrs would not replace your record array. IIRC you can supply slots so it might be useful for converting raw data into your numpy types, but I suspect you'd find the overhead in function calls problematic

If you want easier than recarray and almost as fast I think you're in pandas-ville
