Learning Apache Cassandra - [Free] Learning Apache Cassandra [PDF] [EPUB] - . LEARNING APACHE CASSANDRA. Author: Niklas Gloeckner. The Nursing. Build a scalable, fault-tolerant and highly available data layer for your applications using Apache Cassandra. Cassandra is a NoSQL database with decentralized, fault-tolerant, scalable, and low-cost features, making it a core component of cloud.
There are following properties of NoSQL databases. Design Simplicity Horizontal Scaling High Availability Data structures used in Cassandra are more specified than data structures used in relational databases.
Cassandra data structures are faster than relational database structures. Relational Database Handles data coming in low velocity Handles data coming in high velocity Data arrive from one or few locations Data arrive from many locations Manages structured data Manages structured unstructured and semi-structured data.

Supports complex transactions with joins Supports simple transactions single point of failure with failover No single point of failure Handles data in the moderate volume. Handles data in very high volume Centralized deployments Transactions written in one location Transaction written in many locations Gives read scalability Gives both read and write scalability Deployed in vertical fashion Apache Cassandra Features There are following features that Cassandra provides.
Massively Scalable Architecture: Cassandra has a masterless design where all nodes are at the same level which provides operational simplicity and easy scale out. Masterless Architecture: Data can be written and read on any node.
Linear Scale Performance: As more nodes are added, the performance of Cassandra increases. No Single point of failure: Cassandra replicates data on different nodes that ensures no single point of failure.
Fault Detection and Recovery: Failed nodes can easily be restored and recovered. Data Protection: Data is protected with commit log design and build in security like backup and restore mechanisms. Tunable Data Consistency: Support for strong data consistency across distributed architecture.

CLICK HERE close Features of Cassandra Here in this section of the Cassandra tutorial we will discuss some of the top features of Cassandra Cassandra is highly scalable meaning you can have additional hardware for accommodating more customers and data Cassandra does not have a single point of failure and it has an always on architecture It has fast linear performance which means you can increase the throughput by increasing the number of nodes in the cluster It has a highly flexible data storage meaning all formats of data can be stored including structured, semi-structured and unstructured It allows for easy data distribution by providing the flexibility to distribute data by replicating it across multiple data centers Cassandra supports the ACID compliance which stands for Atomicity, Consistency, Isolation, Durability It performs blazing fast writes without sacrificing the read efficiency.
Here we list some of the top applications of Cassandra.
It is extensively used for monitoring and tracking of applications It is used in web analytics which are heavy write systems It is deployed for social media analysis for providing suggestions to customers It is used in retail applications for product catalogue look ups and inputs It is extensively used as the database for mobile messaging services Why should you learn Cassandra?
Cassandra is a top NoSQL database and it is finding more and more users with each passing day. Since we are living in a world of big data, Cassandra is finding huge acceptance since it was built for big data.
Also a lot of the organizations are moving from the traditional relational database systems to NoSQL databases and thus Cassandra is their natural choice.
All this means that the job market for Cassandra is just heating up and the salaries for Cassandra professionals are among the best in the big data domain. All these are compelling reasons for you to learn Cassandra and excel in your career.
Cassandra Tutorial – Learn Cassandra from Experts
Actually Big data technologies are set of tools specially designed and architect to store, process and analyze big data i. These tools are specially curved to handle variety of data i. Before talking about Cassandra lets first talk about terminologies used in architecture design.
Node: Is computer server where you store your data. It is the basic infrastructure component of Cassandra. Data center :A collection of related nodes.
The simplest way to get started is to download the prebuilt binary. Each Data base will correspond to a real application for example in an online library application data base name could be library.A NoSQL or Not Only SQL is a set of databases that provide a way to store and retrieve data that is not in the standard tabular format followed by relational databases.
The latest version of Apache Cassandra is 3.

Cassandra is a distributed database that stands out thanks to its robust feature set and intuitive interface, while providing high availability and scalability of a distributed data store. Finally, you will implement some application-level optimizations using a Java client.
Chapter 5: You will then see how Cassandra stores data onto files on the disk, how to optimize those files to improve performance, and how to monitor the Cassandra database performance using logs and metrics. Data Modelling in Cassandra.
