Understanding resource usage with node.js, express and nedb

Question

I have created a very simple node.js express application.

It loads about 1 gig of JSON data into a memoryonly nedb database.

So I'm wondering what happens when I try to run this in production?

I don't know how express is deployed but presumably using some sort of web server that executes multiple express processes?

I am wondering if this means that each process will have its own one gigabyte nedb database in memory?

Is there a way to configure such that the one nedb database is shared amongst all the node.js express processes?

Answer 1

it also provide a nodejs module named pm2 that supports clustering for nodejs
