Review Comment:
Instead of adding a public method, how about we maintaining a private list
of transform that supports pyarrow transform for the check at the beginning of
`append`. For transforms that does not yet support pyarrow transform, we could
throw `NotImplementedError` in `pyarrow_transform`
WDYT!
