I hoped to find the opportunity to continue developing OK Log after the spike of its creation. Unfortunately, despite effort, no such opportunity presented itself. Please look at OK Log for inspiration, and consider using the (maintained!) projects that came from it, ulid and run. OK Log is a distributed and coördination-free log management system for big ol' clusters. It's an on-prem solution that's designed to be a sort of building block: easy to understand, easy to operate, and easy to extend.
