Not really, you can use a multiprocessing.Manager to share a plain old dict or list across multiple worker processes: https://docs.python.org/3/library/multiprocessing.html#shari...



I think the OP was talking about different VMs behind a load balancer where there is no shared memory at all.


Wasn't my impression (using worker processes in the same machine is common), but fair enough. On the other hand, message passing across machines is overrated. We run a SaaS service on 25 VMs with no communication between them for regular operation.
