Where as Data Partitioning (discussed in last chapter) is concerned with picking a node to store the first copy of data (row) on, Replication is all about storing additional copies of data on multiple nodes so it can deal with…

Cassandra is a distributed database that runs on multiple nodes. When you write data to the cluster, partitioning scheme determines which node in the cluster stores that data. For example, suppose you are inserting some data (Column-Value pair identified by…
An Associative Array is one of the most basic and useful data structures where each value is identified by a key, usually a string. In contrast, values in a normal array are identified by indices. Associative Array maps keys to…
In terms of it’s architecture, Cassandra is an open source, p2p, distributed data store written in the Java programming language. Distributed, P2P and Fault Tolerant: It is designed to run on multiple nodes and all nodes are equals: you do…
Apache Cassandra is a NoSQL, distributed, post-relational database management system. Cassandra is designed to be: 1. Distributed – Runs and stores data on multiple nodes 2. Peer-To-Peer – Data can be written to any node in the Cassandra cluster and…
