support @cacheControl

[linstantnoodles]

Apollo server implementations recognize cacheControl directives from subgraphs, but there doesn't seem to currently be a way to define this directive on fields.

Apollo Server recognizes the @CacheControl directive, which you can use in your schema to define caching behavior either for a single field, or for all fields that return a particular type.

So basicaly you want to field/fields cache, have I understood correctly?
How about caching through https://github.com/DmitryTsepelev/graphql-ruby-fragment_cache
Cache goes to redis on subgraph level, preventing activerecord call and then all subgraphs reuses all those data.
so the flow would be. It not cached, calls activerecord.
