Mongodb memperbarui semua dokumen dengan id unik

Jika Anda menggunakan MongoDB versi>=4.4 Anda dapat mencoba ini:

db.products.updateMany(
    {},
    [
        {
            $set: {
                secondaryKey: {
                    $function: {
                        body: function() {
                            return UUID().toString().split('"')[1];
                        },
                        args: [],
                        lang: "js"
                    }
                }
            }
        }
    ]
);
