Apache Cassandra is an open source, non relational database management system, designed to handle large amounts of data and offers continuous availability, linear scale performance and easy data distribution across multiple data centers and cloud services. With the evolution of big data, effectively analyzing and storing the huge volumes of data using the traditional RDMS and SQL systems has become outdated. The need for very low levels of latency, previously unknown levels of scale, global distribution of data, continuous availability and reducing operational and software costs have given rise to non relational database category. Although Apache Cassandra provides a feasible solution for handling these non relational databases, the deficit in the number of trained professionals in the application is dwarfing its usability. Cassandra online training alleviates this issue.
- Massive scalability- linear increase in read and write throughput ,as new nodes are added, with no break off in applications
- Active all around design- all nodes can be written to and read from, allowing addition and access anywhere in the world
- Distributed architecture- data distributed in the cluster with each node in the cluster having the same role, hence no single point of failure
- Easy fault detection and recovery- nodes that undergo failure can be easily detected and replaced or restored.
- CQL(Cassandra query language)- an SQL like language, which facilitates easy transition from a relational database
- MapReduce support- has Hadoop integration along with MapReduce support
Advantage over traditional RDBMS
|POINT OF COMPARISON
||Can handle low to medium data velocity
||Handles high data velocity
||Manage only primarily structured data
||Can manage all types of data(NoSQL)
|Point of Failure
||Has a single point of failure
||No single point of failure and has constant uptime
||Supports moderate data volume
||Supports large volumes of data
||Data coming from only one or few locations
||Data sources are multiple and often a large number
The Cassandra Edge
A look at the fields where Cassandra holds a distinct advantage over any other DBMS
- IOT applications– As it can handle high data velocity, it is best suited for IOT applications for consuming lots of fast incoming data from sensors and similar mechanisms present at different locations.
- Retail Applications and product catalogs-Retailers that require dependable shopping cart protection and fast catalog inputs and searches, use Cassandra as the preferred DBMS.
- Messaging and mobile phone- Various mobile apps and messaging service providers employ Cassandra as their database backbone.
- Monitoring User Activity- Most entertainment and media companies use Cassandra to monitor and track the user interaction with their movies, music and other applications.
- Analytics and recommendation on Social media- Many online companies and social media websites use Cassandra to consume and analyze data in order to provide analysis and recommendations to its customers and users.
