πŸ”— Moving persistent data out of Redis - GitHub Engineering

"Recently we made the decision to disable persistence in Redis and stop using it as a source of truth for our data"
"For the majority of callsites, we replaced persistent Redis with GitHub::KV, a MySQL key/value store of our own built atop InnoDB, with features like key expiration. We were able to use GitHub::KV almost identically as we used Redis: from trending repositories and users for the explore page, to rate limiting to spammy user detection."
