It is is an open-source NoSQL database management system (DBMS) that is designed to handle large amounts of data across many servers, providing high availability with no single point of failure.
Meaning if one server fails, everything goes as per normal as data is shared amongst nodes (servers).
Compared to other master/slave models like MongoDB, Cassandra has a master-less model.
It has extremely fast read/write speeds.
You read/write millions of rows of data easily.
Work in progress
