Cross-interpreter support for efficient sharing of frozendicts

Feature or enhancement

Proposal:

The concurrent.interpreters module for subinterpreters handles sharing/sending values across interpreters with direct sharing of some basic immutable types, and a fallback to pickling others. As an immutable container, tuples are supported (as long as all items are themselves shareable). Similarly, I think it would be good to support sharing frozendict without serialization (if keys & values are shareable).

Because dictionaries are so fundamental and common, having a better and more performant way to share such a mapping would significantly improve the experience of using concurrent.interpreters and InterpreterPoolExecutor.

Has this already been discussed elsewhere?

Commencez par lire la documentation de concurrent.interpreters sur le partage d’objets ainsi que la gestion existante des tuples et mappings partageables dans le module. Déterminez comment le partage de frozendict pourrait fonctionner lorsque toutes les clés et valeurs sont partageables ; le travail est considéré comme terminé lorsque les valeurs prises en charge passent d’un interpréteur à l’autre sans pickling et que le comportement est couvert par les tests pertinents.
