partial-update-mutation

When this preview feature is enabled, it automatically generates an input type and mutation to support partial document updates.

Enable this preview when querying via the /graphql endpoint.

For example, if partial-update-mutation is enabled and you import the following schema:

type User {
  username: String!
  password: String!
}

Then, apart from all of the elements that are generated automatically, an additional new partialUpdate<Type> mutation and an additional PartialUpdate<Type>Input input type are created as well:

type Mutation {
  partialUpdateUser(id: ID!, data: PartialUpdateUserInput!): User
}

type PartialUpdateUserInput {
  username: String
  password: String
}

All of the fields are optional in the new input type, and any required fields are validated at runtime when executing the query.
