Slightly related to this, I'm building a ruby gem that lets you create such a workflow: https://gitlab.com/sdwolfz/cache_box_rb https://gitlab.com/sdwolfz/cache_box_rb I guess some slight tweaks for task persitance and a CLI wrapper for it could let you achieve this (although I don't leverage Ractors so no true parallelism yet). Anyway, it still does not have an "official" release, nor a stable API, although the code works well and it's fully tested, as far a I can tell. I might consider providing such wrapper myself in the future as I can definitely see it's utility, but time is short nowadays.
