AppDynamics takes Cassandra out for Beer and Big Data

Welcome Cassandra, let’s start with a quick introduction of who you are and what you can do.
I am a high-performance distributed scalable database.  I am really good at doing lots of operations and growing as your data needs increase, and to top that all off I run on commodity hardware which means I’m really great for running on the cloud.

Awesome, oh by the way, what beer are you drinking tonight?
Tonight I’m drinking a Shiner from good old Texas.

Excellent.  First, I heard it on the grapevine and you did tell me that you’re highly available.  Can you confirm or deny these rumors, and what does that really mean?
Highly available means that a distributed system can lose one or more of its servers and still keep the cluster as a whole up and running.  In other words, because I’m designed to run on commodity hardware, failure should be expected.  In my scenario, I can lose a server and keep on chugging along without the cluster going down.
