About Cassandra DB

The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.Cassandra’s support for replicating across multiple data centers is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages.

Cassandra is :

  1. FAULT TOLERANT : Data is automatically replicated to multiple nodes for fault-tolerance. Replication across multiple data centers is supported. Failed nodes can be replaced with no downtime.

  2. PERFORMANT : Cassandra consistently outperforms popular NoSQL alternatives in benchmarks and real applications, primarily because of fundamental architectural choices.

  3. DECENTRALIZED : There are no single points of failure. There are no network bottlenecks. Every node in the cluster is identical.

  4. SCALABLE : Some of the largest production deployments include Apple’s, Netflix and eBay.

  5. DURABLE : Cassandra is suitable for applications that can’t afford to lose data, even when an entire data center goes down.

  6. ELASTIC : Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.


Prerequisites: Java Python

  1. Create a directory

    mkdir -p ~/Documents/cassandra/
  2. Check the latest version and download the Apache Cassandra binaries from here

    Pavans-MacBook-Pro:cassandra pavanpkulkarni$ curl -O 
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                      Dload  Upload   Total   Spent    Left  Speed

    Pavans-MacBook-Pro:cassandra pavanpkulkarni$
  3. Untar the downloaded file

    Pavans-MacBook-Pro:cassandra pavanpkulkarni$ tar xvfz apache-cassandra-3.11.2-bin.tar.gz
  4. Add Cassandra to ~/.bash_profile file and source it

    #Cassandra Home
    export CASSANDRA_HOME=/Users/pavanpkulkarni/Documents/cassandra/apache-cassandra-3.11.2
    Pavans-MacBook-Pro:cassandra pavanpkulkarni$ source ~/.bash_profile
  5. Verify Installation

    Pavans-MacBook-Pro:cassandra pavanpkulkarni$ cassandra -v
  6. Open a terminal to start Cassandra in foreground

    Pavans-MacBook-Pro:cassandra pavanpkulkarni$ cassandra -f
