Why does my Azure Function to write to MongoDB Atlas have >70s cold start time?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I wonder whether there is a general problem in my function, which leads to such a long cold start. Mongoose has been installed as a dependency which might increase the time. But 70s?!? Come on...
Here is my code. Quite simple really. Just wanna write some stuff to MongoDB. I appreciate any feedback.
module.exports = function(context, req) {
context.log("Function started!");
// Database interaction.
const mongoose = require('mongoose');
const DATABASE = process.env.MongodbAtlas;
// Connect to our Database and handle any bad connections
mongoose.connect(DATABASE);
mongoose.Promise = global.Promise; // Tell Mongoose to use ES6 promises
mongoose.connection.on('error', (err) => {
context.log(`ERROR→ ${err.message}`);
});
// Portfolio Schema.
require('./portfolioModel');
const Portfolio = mongoose.model('Portfolio');
//Create a Portfolio object.
var portfolio = new Portfolio();
portfolio.fiat = "EUR";
portfolio.token[0] = {
crypto_ticker: "BTC",
crypto_name: "Bitcoin",
crypto_qty: 50,
crypto_invested_sum: 9000
};
// Save to db.
portfolio.save();
context.done();
};node.js mongoose

The cold start time was reduced to around 3s once I used the Azure Functions extension for VS Code. The extension is automatically creating a package file and sets WEBSITE_RUN_FROM_PACKAGE=1 (some in-depth infos regarding packaging).
Now "Functions as a Service" gets a lot more interesting.
