Cassandra Training Cassandra
Cassandra is open-source project and a 2nd-generation distributed NoSQL database and is regarded to be the best choice for high availability and scalability databases, particularly when dealing with large amounts of data. Cassandra supports replication across multiple datacentres. Cassandra training course will provide you with an summary of the fundamentals of Big Data and NoSQL databases, its role in the Hadoop Big Data ecosystem, an understanding of Cassandra and its features, architecture and data model, and show you how to install, configure and monitor Cassandra.
