Refreshing the cache to keep it hot, and deciding how to do it, e.g. which parts do we do with the caching layer directly, which parts do we do with an external process, what to evict to make room, etc, are subtopics of cache management.

If I understand you correctly, you're asking if this is different because an external process is involved. I don't see a use in drawing a distinction, and as far as I know, there's no special term for that pattern.

Update: after looking into it, it looks like this cache/architecture pattern is called "refresh-ahead"
