[GitHub] [arrow-nanoarrow] paleolimbot opened a new issue, #71: [R] Required features for initial CRAN release
paleolimbot opened a new issue, #71:
URL: https://github.com/apache/arrow-nanoarrow/issues/71
As requested in #67 and elsewhere:
- [ ] Fix rough edges in arrow -> R conversion (#66)
- [ ] Add `nanoarrow_new_schema()` and `nanoarrow_new_array()` constructors (i.e., create schemas and arrays from very literal interpretations of R objects mapping to the C structs)
- [ ] Add basic R -> arrow conversions (i.e., so that `as_nanoarrow_array(most_data_frames)` will just work). The current versions of these rely on the arrow package...I think that's fine when a complex cast is needed (e.g., `as_nanoarrow(double(), arrow::decimal128(3, 7))`, but most of the time we don't need this and can do a zero-copy "just use the R buffer" approach.
- [ ] Add stream constructors (e.g., stream from `list()` of nanoarrow_arrays, stream from a data.frame that uses ALTREP to avoid materializing columns)
- [ ] (The big one) An official nanoarrow C library release on which to base the R package versioning
...maybe others?

I didn't quite get to the full suite of conversions for 0.1 or 0.2; however, I've opened up issues to track towards that goal for 0.3!
