URL: https://github.com/apache/arrow/issues/10531


   I'd like to resolve this warning 
   ```
   /usr/lib/python3.7/asyncio/events.py:88: FutureWarning: 
'pyarrow.deserialize' is deprecated as of 2.0.0 and will be removed in a future 
version. Use pickle or the pyarrow IPC functionality instead.
   ```
   I'm calling `pyarrow.deserialize` on a bytes-like object that was initially 
a dictionary, but then stored in the plasma store with `client.put` and 
retrieved with 
   
   ```python
   buff = plasma_client.get_buffers([object_id])[0]                             
                                                                                
                                                                                
 reader = pyarrow.BufferReader(buff)                                            
                                                                                
                                                                               
data = reader.read()   
   ```
   
   Starting with the bytes in `data`, is there a different method than 
`pyarrow.deserialize` to retrieve the original dictionary?
   
   Thank you for arrow! Happy to move this to JIRA if you'd prefer.
