Back Pressure, or, Don't Accept Work Before You're Ready [I] - Sam Roberts, IBM Canada

Sign up or log in to save this to your schedule and see who's attending!

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).
