MongoDB: Update many documents with different data in each

Question

I have an array of _id:

ordersId = ["5ec42446347f396fc3d86a3d", "5ec422d4347f396fc3d86a3c", "5ecefaf0aead3070fbdab7dd"]

And I'm trying to update the documents that match these _ids, but with different data in each of them:

    const existentOrders = await Orders.updateMany(
        { _id: { $in: ordersId } },
        {
            $set: {
                status: "Reviewing",
                cashier: req.id,
                rate: dataBasedOnId,
            },
        }
    );

I have an array of objects that also have these ids:

const ordersRates = [
  {
    _id: "5ec42446347f396fc3d86a3d"
    rate: 2434686948.19
  },
  {
    _id: "5ec422d4347f396fc3d86a3c"
    rate: 2434686948.19
  },
  {
    _id: "5ecefaf0aead3070fbdab7dd",
    rate: 93320.00
  }
]

So what I'm trying to do is to update each document with the rate that is in the ordersRate variable.

Is it possible to update them using only one operation?

Thanks!

I would suggest you to use bulk write which will save network round trip time instead using multiple requests.

You have two variables and form list of UpdateOne operations and pass it to bulk write.
