Dehydrating a big query into separate keys

[shahinghasemi]

Hello guys.
My backend is written in graphql. I have type called Organization which is something like this:

type Organization {
   id: string
   name: string;
   products: Product[];
   staffs: Staff[];
}

I want to fetch Organization in the react server component in one single query and includes staffs and products.
I have two questions:

1. Is it possible to extract and store the products and staffs in Organization into separate keys ? Because these data are going to be used in different places so I don't want to re-fetch them again. I want to use the cache instead of separate network call in client side.
2. Is it possible to know in the server side that what keys are stored in our client-side cache? for example when request reaches into the server component i want to know if the key categories exists in the store then I should not re-fetch the categories on the server side.
