Hi all, We have been using Arrow v2.0.0 and we encountered the following issue.
I was reading a table with numeric data using pandas.read_csv and then converting it into pyarrow table. In our application (Cylon <https://github.com/cylondata/cylon>), we are accessing this pyarrow table from c++. We want to access the mutable data of the arrays in the pyarrow table. But the following returns a nullptr. T *mutable_data = array->data()->GetMutableValues<T>(1); // returns nullptr Interestingly, array->data()->buffers[1]->IsMutable(); // returns true array->data()->buffers[1]->IsCpu(); // returns true This only happens when I use pandas df to create a pyarrow table. It wouldn't happen when I use pyarrow.read_csv. So, I am guessing there's some issue in the buffer creation from pandas df. Is this an expected behavior? or has this been resolved in v2.0< releases?
