With posts like this, I think it's important to remember that projects like this get created for one primary reason: it solves problems AirBnB has. If you're lucky, it solves problems you have too. I work on some tech giant cyber security stuff, and it's obvious if you look at it that what my team designs solves a tech giant scale problem in the context of past engineering decisions made to solve other tech giant scale problems this company had. I probably wouldn't recommend my team's approaches to anyone who has less than ~5000 engineers. From this experience I've adopted a heuristic: first consider the scale the system was built to address. If you are not in the ballpark of that scale, give it a long hard look before you adopted it.
