At Honeybadger, we use Redis a lot. It's our Swiss Army Knife; it's a cache, a single source of truth, it stores background jobs, and more. Basically, Redis is one of those services that should never fail. I was pondering the DevOps apocalypse recently, as one does (could Redis be one of the four horsemen?), which led me to jump into our #ops channel to ask Ben a simple question: what are the risks if someone executed flushall on our redis instances?
