Cassandra Training Overview
Apache Cassandra is an open source second-generation distributed database released by Facebook. The write-optimized and shared-nothing architecture results in excellent performance and scalability. The master class ring design of Apache Cassandra makes it elegant, easy setup and maintenance. Cassandra used to provide a simple solution for complex problems like Metrics and Logging. Cassandra is the small footprint of Major or Primary Database so easy to learn. Cassandra used to handles a large amount of data and operate massive data. This Cassandra Training will provide you extensive knowledge of Cassandra concepts, high-scalable data models and the Cassandra architecture which will enable you to build applications for big data.
