Not Ready To Take The Chances

Someone built an entire microservice with a dedicated 3-person team, a database, and a kanban board... to avoid UUID collisions. You know, that thing with a probability so low that you're more likely to win the lottery while being struck by lightning.

For context: UUID v4 has 122 random bits, giving you roughly 5.3×10³⁶ possible values. The odds of a collision are so astronomically small that the universe will probably end before you see one. But sure, let's spin up a whole team to check every UUID against a database because "peace of mind."

Three engineers. Sprints. A database guy. All to solve a problem that doesn't exist. This is what happens when someone reads "theoretically possible" and hears "imminent threat." The collision already happened once though, so maybe they're onto something. Or maybe they just needed to justify headcount.

Peak enterprise architecture right there.
