Redis Cache Hit Ratio

Nine. Hours. NINE WHOLE HOURS hunting down a production bug like a detective in a noir film, only to discover the culprit was a missing colon or dot in a Redis key name. Your entire caching infrastructure just yeeted itself into oblivion because someone typed "user123data" instead of "user:123:data" during deployment. Meanwhile your significant other is sitting there watching you have a full mental breakdown over punctuation. The absolute TRAGEDY of it all – your cache hit ratio went from hero to zero, your database is crying, your servers are on fire, and all because of one tiny character. Romance is truly dead when Redis namespaces are involved.
