> Hi Everyone,
> First of all, well-done! This project is totally awesome.
> When I attempted to serialize a Python object that uses __slots__ to minimize memory requirements I received the following error:
> return pyarrow.deserialize(data, serialization_context)
> File "pyarrow/serialization.pxi", line 461, in pyarrow.lib.deserialize
> File "pyarrow/serialization.pxi", line 424, in pyarrow.lib.deserialize_from
> File "pyarrow/serialization.pxi", line 275, in pyarrow.lib.SerializedPyObject.deserialize
> File "pyarrow/serialization.pxi", line 194, in pyarrow.lib.SerializationContext._deserialize_callback
> AttributeError: 'RemoteExecutorObject' object has no attribute '__dict__'
> Would it be possible to support __slots__? If not, not a huge deal, but wanted to at least ask.
>
> Thanks, and thanks again for pyarrow!
>
> --John
