> Sometimes, it is very hard for the data consumer to know whether an object is a buffer or other objects. If we use try-catch to catch the pyarrow deserialization exception and then using `plasma_client.get_buffer`, the code is not clean.
> We may leverage the metadata which is not used at all to mark the buffer data. In the client of other language, this would be simple to implement.
