There is no "one size" fits all database or distributed system in existence. To say that there is is to say that MySQL is equally as well suited to all use cases as Cassandra or Redis. They all store and serve data, right?

Cassandra makes no claims to be such a holy grail. Read their documentation, and you can see the use cases it is good for and those it is not.

The author of this blog post chose one it is not good for.

Put another way, "I'm sorry that the Lamborghini you bought broke when you attempted to go off-roading with it. Perhaps you should have bought a Jeep instead?"
