The unreasonable effectiveness of key value databases
summary
Argues that key‑value databases like Redis and Valky are everywhere because they map to application local variables, deliver very low latency and high throughput and can transform an app with four lines of code. Claims anyone can learn all Valky/Redis datatypes in about 8 hours, so adoption spreads across teams, but memory costs and optimization become the real bottleneck. Announces Percona packages and a Docker image for Valky (released ~23 and ~2 hours ago) and ongoing Percona contributions to Valky.
