This concept refers to the no-SQL system. It is distributed database management system. Cassandra is written in Java language and combines a fully distributed hash Dynamo system. It means that the concept provides linear scalability with increasing amount of database. Cassandra belongs to the category of high-resecure – data stored in the database are automatically replicated to multiple nodes in the distributed network, or even distributed to several data centers. Cassandra uses a ColumnFamily-based data storage model and it provides the ability to organize hashes with multiple levels of nesting, therefore, it is different from memcacheDB systems. When a node fails, its functions are picked up by other nodes. Above mentioned organization ensure adding new nodes to the cluster and updating the version of Cassandra without additional manual intervention and reconfiguration of other nodes. However, despite perfect organized system Cassandra Query Language essentially truncated in functionality and fulfilled only the most basic requests.
