Fun Facts About ScyllaDB

From Hypervisor Hackers to Database Disruptors

ScyllaDB's origin story is rooted in deep systems expertise. The company was founded in 2012 by Avi Kivity and Dor Laor, the brilliant minds behind the KVM hypervisor - you know, that technology that basically powers most of today's cloud infrastructure. They initially set out to build OSv, a revolutionary cloud-based operating system, and were having great success improving database performance along the way. But then they hit a wall with Apache Cassandra. No matter what they tried, they couldn't push it past a certain performance ceiling due to fundamental architectural limitations.

\ So what did they do? They made the bold (some might say crazy) decision to rebuild the entire thing from scratch in C++. The result? A database that can handle 1 million transactions per second on a single server. Not too shabby for a "let's start over" moment.

The Discord Migration That Made Headlines

One of ScyllaDB's most famous success stories is Discord's migration of trillions of messages from Cassandra to ScyllaDB. And we're not talking about a small app here - Discord has over 350 million users who collectively send an astronomical number of messages every day, and ScyllaDB handles all of it.

\ Here's the heartwarming part: CEO Dor Laor mentioned in a recent interview that he has a special soft spot for the Discord deployment because "my son was very excited and proud about this." Even database CEOs get proud parent moments when their tech powers their kids' favorite apps.

Monster Scale in Real Numbers

When ScyllaDB says they handle "monster scale," they're not exaggerating. Check out these real-world deployments:

• Palo Alto Networks runs over 10,000 clusters on ScyllaDB (yes, you read that right, ten thousand)
• China Mobile operates a mind-boggling 4 petabyte, 180-server workload
• Disney+ Hotstar uses ScyllaDB to deliver instant recommendations to hundreds of millions of viewers

\ These aren't just impressive numbers on a spec sheet, they represent the real-time experiences millions of people have every day. Whether it's your morning Starbucks mobile order, your evening Discord gaming session, or binge-watching your favorite show, there's a good chance ScyllaDB is working behind the scenes to make it all feel instant and seamless.
