Fault Tolerant: Data is automatically replicated to multiple nodes for fault-tolerance.
Performant: Cassandra consistently outperforms popular NoSQL alternatives in benchmarks and real applications.
Decentralized: there are no single points of failure. There are no network bottlenecks. Every node in the custer is identical.
Durable: Cassandra is suitable for applications that can’t afford to lose data, even when an whole data center goes down.
You’re in Control: Choose between synchronous or asynchronous replication for each update.
Elastic: Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
Professionally Supported: Cassandra support contracts and services are available from third parties.
