> One problem with Redis is that it looks superficially simple, but actually, like any tool used in critical contexts ... Definitely. And on top of that, Redis is very easy to get started with, and as the article illustrates, you can plug along very smoothly until you suddenly find a mountain to climb. Shouldn't scare someone off, but one of the lessons is to understand what you're implementing and where the bottlenecks will eventually be - much easier said than done, in my experience, but something to aim for.
