Hey everyone! This is one of those things that’s already been done, but I feel like none of the existing solutions have nailed down an ergonomic API or feature set for storing key-value pairs, especially numerical data. I built this over the weekend to help me store auto-expiring counters for metrics collection for different apps and devices. Hope it’s useful for someone :)
