   with the last gist I posted, it's practically viable, with one open question being how can we minimize the actual bytes movement in this call
   ```julia
   julia> pywith(pa.ipc.new_stream(jl_sink, batch.schema)) do writer
                  writer.write_batch(batch)
              end;
   ```
   
   essentially, the question is if it's possible to get the ipc bytes for a pyarrow batch:
   ```
   Python RecordBatch:
   pyarrow.RecordBatch
   ```
   
   without copying them through a Julia `IOBuffer`
