- [ ] With free-threading, could _convert_column_data be called in parallel for each column?
- [ ] (free-threading) For large files, split into chunks and parse in parallel, then concat?
- [ ] In a pyarrow-always-available world, could
_string_box_utf8
allocate a buffer+mask rather than ndarray[object]? - [ ] #17743
Anyone else have more ideas?
