restore a varying number of different keys?

Hi there,

I am currently setting up an action workflow where many small jobs compute bits of information that need to be passed on to other jobs in a directed acyclic graph as cache objects.
A major challenge for me in defining this elegantly is that I would like each job to use the same reusable workflow template, but need the jobs to be able to restore a varying number of caches with different known cache keys (as the number of parent jobs in the graph can differ).

However, I can't find an action interface that can restore multiple keys together or a way to iterate the cache/restore action within a single job. Is this simply not supported or am I just unable to see a valid way to do this?

Start by reviewing the GitHub Actions cache/restore action interface and reusable workflow behavior described in the issue. Determine whether one job can restore multiple known cache keys or iterate cache/restore, and define done as either a documented supported approach or a clearly scoped proposal for enabling it.
