> It all feels a bit weird to operate in terms of single values, i.e. via the `Append()` methods, since R does not have such concept, this has to resort to many casting. This converter API was designed to operate on list-like collections of generic objects one-by-one. We have different code paths for more efficient conversion from numpy/pandas, see [here](https://github.com/apache/arrow/blob/master/cpp/src/arrow/python/numpy_to_arrow.cc). > Would it make sense to have some sort of vectorised approach ? I think so, yes. We could extend the converter API to consume columns instead of individual values. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
