   Thanks for the review!
   
   > It might be nice to have a convenience for prebuffering an entire row group. Something like

   > rg->PreBufferAllColumns();
   
   I think it's not worth it given this is a relatively low-level API, but may be handy if you do expect people to be using this directly often (instead of via ArrowReaderProperties).
