Node Js Performance

Question

Welcome ... I'm working with Node js and i have a problem Performance Problem Is this code better ... From my point of view the first one not the best because it may takes time for searching about specific item

cart: {
    items: [{
        productId: {
            type: Schema.Types.ObjectId,
            ref: 'Product'
        },
        offerId: {
            type: Schema.Types.ObjectId,
            ref: 'Offer'
        },
        quantity: {
            type: Number,
            required: true
        }
    }]
}

Or this

product_cart: {
    items: [{
        productId: {
            type: Schema.Types.ObjectId,
            ref: 'Product'
        },
        quantity: {
            type: Number,
            required: true
        }
    }]
},
offer_cart: {
    items: [{
        offerId: {
            type: Schema.Types.ObjectId,
            ref: 'Offer'
        },
        quantity: {
            type: Number,
            required: true
        }
    }]
},

Which of two codes are the best for performance ?

Well, your question is wrong. Nodejs does not have to do with this. All operation is done on MongoDB Side — Manjeet Singh

Muhammad, you need to restructure your question. 1. Are you asking how to improve the performance of node js when you process this JSON in node js? 2. How to improve MongoDB schema for better performance? — Sathik Khan

First of all your question is very generic. If the question is regarding on run-time preformance it depends on many factors not only the model schema. In any case you can use mongoose populate in order to access a specific field which your ObjectId is refering to. If this is your intention, You can read more aboute mongoose populate() here: https://mongoosejs.com/docs/populate.html
