> arrow compressed files, such as one produced with R arrow::write_feather are much smaller than those created with write_ipc_stream.
> And of course on the web it makes a big difference.
> But i can't properly read such 'feather' files with Arrow js (arrow.Table.from).
> For instance dictionary values are not properly decoded
