How to awoid 'SELECT *' in graphql?

Question

I'm pulling data from database using graphql, but something is bothering me a lot.

/App.js:

import { schema } from './graphql/index.js';
...
app.post(
  '/graphql',
  graphqlHTTP({
    schema: schema,
  })
);

/graphql/index.js:

import { GraphQLObjectType, GraphQLSchema, GraphQLList } from 'graphql';
import { DB_GetAllCustomers } from '../services/database/customers.js';
import { TYPE_Customer } from './typedef/customers.js';

const RootQuery = new GraphQLObjectType({
  name: 'RootQuery',
  fields: {
    getAllCustomers: {
      type: new GraphQLList(TYPE_Customer),
      resolve: async () => {
        const data = await DB_GetAllCustomers();
        console.log(data[0]);
        return data[0];
      },
    },
  },
});

const RootMutation = new GraphQLObjectType({
  name: 'RootMutation',
  fields: {
    ...
    ...
  },
});

export const schema = new GraphQLSchema({
  query: RootQuery,
  mutation: RootMutation,
});

/graphql/typedef/customers.js:

import graphql, { GraphQLObjectType } from 'graphql';

export const TYPE_Customer = new GraphQLObjectType({
  name: 'Customer',
  fields: () => ({
    id: { type: graphql.GraphQLString },
    username: { type: graphql.GraphQLString },
    email: { type: graphql.GraphQLString },
    mobile: { type: graphql.GraphQLString },
    password: { type: graphql.GraphQLString },
    _active: { type: graphql.GraphQLInt },
    _suspended: { type: graphql.GraphQLInt },
  }),
});

The DB:

/services/database/customers.js:

export const DB_GetAllCustomers = () => {
  return db.execute('SELECT * FROM customers').catch((err) => {
    throw err;
  });
};

---

So, lets say my graphql request is

  query RootQuery{
     getAllCustomers{
       id
     }
  }

here I just want to get IDs of all customers.

It works as expected:

But the problem is, as you see I debug RootQuery:

and the logs:

Here the graphql front side works as it should, but the database side you see, unnecessary data requests are made.

How can I optimize this, any best practice?

(note: I can't just "SELECT id FROM customers" because graphql scalability should not be limited.)
