I have Booking model with field [status(type:String)] and can only have four values NEW,ALLOTED,CANCELLED,COMPLETED . And also I have Customer model ,which has field [bookings(as array of Booking ("ref"))]

Actually I need four arrays for four values of status (for , NEW,ALLOTED,CANCELLED,COMPLETED),from Customer model (customer _id is given) via bookings array (also populated),

can deal with aggregate in mongoose?!

For that I first have to get all documents and then I have to iterate over all and then ,by (if-else ladder) I can push documents according to values. Or by doing four queries through aggregate. But actually I have large number of documents ,so I think it will not be efficient

Is there any other way to do this in javascript or in mongoose,mongodb(via queries). I am beginner .Please Help ,Thank You! (For nodejs)

const bookingSchema = new Schema({
    category: {
        type: String,
       default: null
     },
     status: {
      type: String,
        enum: {
            values: ["NEW", "ALLOTED", "COMPLETED", "CANCELLED"],
              message: "bad status"
            },
           default: "NEW",
           required: true
       }
     })





const customerSchema= new Schema({
    email: {
        type: String,
       required:true
     },

   bookings: [
   {
    type: Schema.Types.ObjectId,
      ref: 'Booking'
    }
   ],
})
