What I like about this talk is that it is honest. You can tell this guy wasn't sitting in an ivory tower telling the peons how to fix the problems, he actually lived it.
Pfft. Just means they've moved the schema definition into the content of the table. That's exactly what they are: Things. It's just a different data architecture.
Talks like this are great examples that all systems evolve to what they are like today. Nothing is designed perfectly like those in system design interviews.
front end application in node? Say its served by node. its not node. I was not expecting it from reddit. People like you made our life miserable by seeing front end node.js developer job posts. Which does not make sense .
Node is still used by the bundlers used to compile their front end (whether it's React or Web Components). I can't imagine why a front-end engineer wouldn't know how to use Node these days. It's not that hard if you already know JavaScript. And, if you don't know JavaScript, aren't you more of a designer than anything?
