Certified Cassandra DB and NoSQL


The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance.This course will introduced you to the NoSQL datastores and understand where Cassandra fits in. You will understand how Cassandra doesn't have a single point of failure, it's comparison with relational databases, how it's easy to scale.Participants will understand the advantages of Cassandra over other NoSQL systems, some real world cases when we use Cassandra.Also will get to see the data model of Cassandra (Keyspaces, Column families), use CQL to do things with it. You will also get to see a typical read and write flow, and understand what bloom filters are. This will be a decently hands on training.

Hardware and Softwares Required for this training:

Delegates attending this course are required to carry a laptop with below configuration. Usually we suggest a 64 bit machine and not a 32 bit machine. However you can still try with a 32 bit machine but we do not gaurantee if the programs will run without any error. 

Windows user64 bit OS, Min 4 GB RAMVMWare Player 5.0.0Linux  VM– Ubuntu 12.04 LTS : {Unicom will be providing the VM(virtual machine)}Eclipse 3.6+Putty – For opening Telnet sessions to the Linux VMWinSCP – For transferring files between Windows and Linux VM

Linux/Mac Users (preferably a 64 bit machine): Min 4 GB RAM Eclipse 3.6+JDK 1.6 or higher installed on your machineSSH installed

Systems with said configuration can be arranged through us with an additional cost.



Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters with asynchronous master less replication allowing low latency operations for all clients.

Cassandra also places a high value on performance. University of Toronto researchers studying NoSQL systems concluded that "In terms of scalability, there is a clear winner throughout our experiments. Cassandra achieves the highest throughput for the maximum number of nodes in all experiments.
