Is anyone here fairly familiar with either Relay or Apollo Client?

🙋 with apollo client under EmberJS.

@boubalou that could work! I have a bit of an edge-case question on how to handle a specific kind of mutation

An example is worth a thousand words, so check out this mutation: https://www.graph.cool/docs/reference/relay-api/nested-connect-mutations-ec6aegaiso/#nested-connect-mutations-for-to-one-relations

I am not using graphql.cool but their example demonstrates my issue

Basically, I have a mutation (like on the example) which “connects” two nodes

usually, you want your mutations to return all the data that might have changed

so that you can update your local cache (in this case, managed by apollo)

either automatically or imperatively

in this scenario, however, the whole “subtree” under the “contactDetails” field may have changed

e.g. I could have a view which queries deep inside “contactDetails”, and when I set a new node for “contactDetails” on my object the whole data this view is rendering might be affected

and I can’t know which fields to ask for in the mutation payload in advance

as this may be an arbitrarily large subtree

if that makes any sense
