Imagine a world where your favorite websites suddenly load faster than ever, where millions of people can access information at the exact same moment without a hiccup. This dream often bumps into a wall called database performance. For years, many people believed MySQL, a popular database, had a hard limit, a ceiling it just couldn't break through for truly massive scale.

Then, a team achieved something that seemed impossible: one million queries per second with MySQL. This wasn't just a small improvement, it was a giant leap. But like many incredible technical stories, the details of how they did it, and the impact it had, often get overlooked.
