200: Tech Tales FoundFrom Frustration to Revolution: The Redis Story and the Open Source BattleRedis began as a personal project by Salvatore Sanfilippo, an Italian programmer struggling with slow databases at his startup. In 2009, frustrated with performance limitations, he created a fast in-memory data store prototype called LMDB, which later evolved into Redis. Unlike traditional databases that relied on slower disk storage, Redis stored data directly in RAM, enabling lightning-fast access—around 100 nanoseconds compared to milliseconds for solid-state drives. This speed made it ideal for real-time applications like social media feeds, online gaming leaderboards, chat services, and session management. Redis quickly gained traction within the Ruby on Rails community after developer Ezra Zygmuntowicz pr...2025-06-0537 min
