There was a problem hiding this comment.
I think these fields should always exist. Shall we also simply add an .expect("engine core client requires at least one engine")?

Purpose
Add parallel config for world size in
EngineCoreReadyResponsethat is captured and persisted during startup and served directly. This makes the implementation fast but there are cases such as Elastic DP where ranks can change after startup. For those cases. We have two options:config_updateto capture all sort of config updates from the Engine.I will open a separate discussion for that but for now this implementation should be fine.
