Tips for efficiently inserting 10,000 records into MongoDB with identical keys and values

I am currently focused on developing the server side functionality for a new game application.

This game will feature a spin wheel concept, and in order to implement this, I need to store a large amount of records. Specifically, I will need to store 10,000 records for 100 coins, 5,000 records for 200 coins, 100 records for 500 coins, as well as 1 record each for 1000 coins and 10,000 coins.

To handle this data storage, I plan to run a cron job at the end of each day to store documents and remove all records from the previous day.

When the spin wheel is activated, a random document will be selected from the available (unused) documents.

//Document Structure
{
    "No_of_Coins": 100,
    "position": 4,
    "Recorded_Spin": false,
    "date": new Date()
}

While I could use a for loop to insert the 10,000 records sequentially, I am looking for a faster and more efficient approach to implement this algorithm.

Answer №1

To populate your database with 10000 items, you can simply create an array containing all the items and then use the insertMany method to insert them.

const dataArray = new Array(10000).fill({
    "No_of_Coins": 100,
    "position": 4,
    "Recorded_Spin": false,
    "date": new Date()
})

db.collection.insertMany(dataArray);

Answer №2

function generateCoinsArray(coins, times, data) {
  return coins.flatMap((coin, index) => Array(data[index] || times).fill(coin));
}

var coinsData = [{
  "No_of_Coins": 100,
  "position": 4,
  "Recorded_Spin": false,
  "date": new Date()
}];

var resultArray = generateCoinsArray(coinsData, 1000, coinsData[0]);
console.log(resultArray);

Let's give this code a shot.
