Back pressure is a network protocol concept that is key to writing node services that perform well under load, and that don't accept more work than they are ready to do or store data without bounds if the data can't be acted on (yet). Scalability is a strength of Node.js, but requires careful construction of data flow in your application to break up CPU processing so multiple large requests can make progress simultaneously. Learn how streams support back pressure and how you can take advantage of it in your applications.
