Contrasting Hadoop & Apache Cassandra â¢ Apache Cassandra is a NoSQL database ideal for high-speed, online transactional data, while Hadoop is a big data analytics system that focuses on data warehousing and data lake use cases.
Cassandra is designed as a distributed system, for deployment of large numbers of nodes across multiple data centers. Key features of Cassandraâs distributed architecture are specifically tailored for multiple-data center deployment, for redundancy, for failover and disaster recovery.
