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.
Apache Cassandra is a superior NoSQL database platform for these types of Big Data challenges. Cassandraâs data model is an excellent fit for handling data in sequence regardless of datatype or size. When writing data to Cassandra, data is sorted and written sequentially to disk.
