Apache cassandra is an open-source, user-available, distributed, NoSQL DBMS that is designed to handle large amounts of data across many servers. It provides zero points of failure. Cassandra offers massive support for clusters spanning multiple datacentres.

 

There are some massive features of Cassandra. Here are some of the features described below-


1. Distributed- Each node in the cluster has the same role. There’s no question of failure & the data set is distributed across the cluster but one issue is there that is the master isn’t present in each node to support request for service.

 

2. Supports replication & Multi data center replication- Replication factor comes with the best configurations in cassandra. Cassandra is designed to have a distributed system, for the deployment of a large number of nodes across multiple data centers and other key features too.

 

3. Scalability- It is designed to r/w throughput, Increase gradually as new machines are added without interrupting other applications.

 

4. Fault-tolerance- Data is automatically stored & replicated for fault-tolerance. If a node Fails, then it is replaced within no time.

 

5. MapReduce support- It supports Hadoop integration with MapReduce support. Apache Hive & Apache Pig is also supported.

 

6. Query Language- Cassandra has introduced the CQL(Cassandra Query Langugae). It's a simple interface for accessing the Cassandra.
