I have a large object that I want to save to the disk because it takes a minute to generate. The OOM reaper kills the process while pickle.dump ing the object.

It's a tuple of dicts of tuple of array.array.

Can pickle dump in chunks? If not, is there another technique I can use?

If you're pickling that much data you should definitely consider using a more appropriate data format. Maybe a database or HDF5?

Agreed. When I started, things were much simpler. Trying not to revise too much code but I can if there's no other option.
