Schema Stitching. Combining multiple schemas into one

[k-kundan]

If I have the following two remote GraphQL schemas:

type Event {
  date: String
  location: String
}

Query {
   event(date: String): Event
}

type Weather {
  temperature Int
  condition String
  windSpeed: Int
}

Query {
  forecast(location: String): Weather
}

I should be able to stich them toghether and perform the following query:

query GetEvent($date: String) {
  event(date: $date) {
    location {
      temperature
    }
  }
}
