    Cassandra database provides a number of benefits. Key benefits of Cassandra database are:

    • Fault Tolerant: It is fault tolerant. Cassandra automatically replicates data to multiple nodes for fault tolerance. Any failed node is replaced immediately with no downtime.
    • Decentralized: It is based on decentralized approach. Every node in Cassandra database cluster is identical. Also there are no network bottlenecks. – Every node in the cluster is identical. There are no network bottlenecks.

    It is used to describe a database that does not expose an SQL interface. This term was first introduced in 1998. In 2009, Eric Evans, employee of Rackspace has introduced it again as he wants to organize an event on open source distributed databases.

    Why Cassandra shall be chosen against any other NoSQL solution?

    • Main selling point of Cassandra is that it is being written in Java.
    • Cassandra has been present on the largest website of the world i.e. Face book.
    • Cassandra has met all the requirements to be decentralized and it doesn’t have one single failure point.
    • Read as well write throughput have been seen to increase in linear fashion, when newer machines get added without any sort of downtime or interruption.
    • It gets

  4. What is Cassandra?

    by , 02-21-2012 at 08:06 PM
    The Apache Cassandra Project is involved in creating the highly scalable database that is second generation distributed. It brings the Bigtable’s ColumnFamily (based data model) & fully distributed design of Dynamo, together.

    Apache Cassandra is basically an open source that is a highly available database and distributed. Architecture of Apache Cassandra incorporates the design, from Dynamo project. It makes use of data model that is Google’s Bigtable data model based.
