Benefits
Cassandra Database online training course will teach you to architect and engineer Cassandra databases for competitive advantage, model data in Cassandra based on query patterns and access Cassandra databases using CQL and Java. In addition, you learn how to create a balance between read/write speed and consistency, integrate Cassandra with Hadoop, Pig and Hive and implement commonly used Cassandra design patterns.
Apache Cassandra is a free and open-source, distributed, wide column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
Cassandra is in use at Constant Contact, CERN, Comcast, eBay, GitHub, GoDaddy, Hulu, Instagram, Intuit, Netflix, Reddit, The Weather Channel, and over 1500 more companies that have large, active data sets.
Cassandra is a peer-to-peer distributed system made up of a cluster of nodes in which any node can accept a read or write request. Similar to Amazon's Dynamo DB, every node in the cluster communicates state information about itself and other nodes using the peer-to-peer gossip communication protocol.

Cassandra isn't too bad. You have to learn to build tables as if you were building around materialized views. The people making cassandra DB try to make it as easy as possible to learn. The hard part is designing how you want to distribute your data and what tables to build.
We all know that Cassandra is a NoSql Database. So it offers a solution for problems where one of your requirements is to have a very heavy write system and you want to have a quite responsive reporting system on top of that stored data.
