      Description copied from class: MyQueryTypeController
      This method loads the data for ${dataFetcher.graphQLType}.checkOverriddenController.
      For optimization, this method returns a CompletableFuture. This allows to use graphql-java java-dataloader to highly optimize the number of requests to the server.
      The principle is this one: The data loader collects all the data to load, avoid to load several times the same data, and allows parallel execution of the queries, if multiple queries are to be run.
      You can implements this method like the sample below:
       public CompletableFuture<List> friends(DataFetchingEnvironment environment,
                      DataLoader<Long, Member> dataLoader, Human origin) {
              List<java.lang.Long> friendIds = origin.getFriendIds();
              DataLoader<java.lang.Long, CharacterImpl> dataLoader = environment.getDataLoader("Character");
              return dataLoader.loadMany(friendIds);
