* Fault Tolerant - Data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime. * Performant - Cassandra consistently outperforms popular NoSQL alternatives in benchmarks and real applications, primarily because of fundamental architectural choices. * Decentralized - There are no single points of failure. There are no network bottlenecks. Every node in the cluster is identical. * Durable - Cassandra is suitable for applications that can't afford to lose data, even when an entire data center goes down. * You're in Control - Choose between synchronous or asynchronous replication for each update. Highly available asynchronous operations are optimized with features like Hinted Handoff and Read Repair. * Elastic - Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications. * Proven - Cassandra is in use at Constant Contact, CERN, Comcast, eBay, GitHub, GoDaddy, Hulu, Instagram, Intuit, Netflix, Reddit, The Weather Channel, and over 1500 more companies that have large, active data sets.

* Fast processing of OLAP workloads. * Integration with MapReduce, Spark and other Hadoop ecosystem components. * Tight integration with Cloudera Impala, making it a good, mutable alternative to using HDFS with Parquet. * Strong but flexible consistency model, allowing you to choose consistency requirements on a per-request basis, including the option for strict-serializable consistency. * Strong performance for running sequential and random workloads simultaneously. * Easy to administer and manage with Cloudera Manager. * High availability. Tablet Servers and Masters use the Raft Consensus Algorithm, which ensures that as long as more than half the total number of replicas is available, the tablet is available for reads and writes. For instance, if 2 out of 3 replicas or 3 out of 5 replicas are available, the tablet is available. * Reads can be serviced by read-only follower tablets, even in the event of a leader tablet failure. * Structured data model.
