Hello

I don't find in the doc the answer to my question.
I have a multi tenant app and all my queries are scoped using @key indexes. (to be more efficient)
I now want to switch to the new Datastore service. How to use my custom indexes to query data using Datastore? I know queries are done against the local storage, but when sync against my dynamo db table I want those queries to be efficient and to use my indexes and therefore avoid scan operations.

The same problem exists for subscription: I want to be able to scope my obersvers to only scoped data. I dont want to get all updated, just those i'm concerned for (in my tenant scope)
I was able to override subscriptions using graphql API but it seems i can use them with datastore.

We are going to be adding this functionality in the near future as noted in the below issues. In the meantime, can you provide us with explicit examples of your GraphQL schema and how you might like the scoping to look?

@undefobj I am going through a similar issue as @mdebo. Where would the best place to provide examples be? This thread?
