What is Cassandra?
Cassandra is a distributed database management system that is built to handle huge amounts of information across multiple data centers and the cloud. It is highly scalable, provides high availability, and has no single point of failure. Written in Java, it’s a NoSQL database providing many things that other NoSQL and relational databases cannot.
What is a NoSQL Database?
A NoSQL, often referred to as “not only SQL”, database is one that stores and retrieves information without requiring data to be stored in tabular format. Unlike relational databases, which need a tabular format, NoSQL databases enable for unstructured data. This type of database provides a simple design, horizontal scaling, and extensive control over availability. It does not need a fixed schema, it offers for simple replication, it has a simple API, it’s generally consistent, and it can handle huge amounts of data.
What Makes Apache Cassandra Unique?
It is one of the most efficient and widely-used NoSQL databases. One of the key benefits of this system is that it provides highly-available service and no single point of failure. This is key for businesses that can afford to have their system go down or to lose information. With no single point of failure, it provides truly consistent access and availability.
There is another major benefit of Cassandra is the massive volume of data that the system can handle. It can effectively and efficiently handle large amounts of information across multiple servers. In addition, it is able to fast write large amounts of data without affecting the read efficiency. Cassandra provides customers “blazingly fast writes,” and the speed or accuracy is unaffected by huge volumes of data. It is just as fast and as accurate for large volumes of data as it is for smaller volumes.
Who Should Use Cassandra?
If you are required to store and manage huge amounts of data across many servers, Cassandra could be a good solution for your organization. It’s ideal for enterprises that can’t afford for information to be lost or that can’t have their database down due to the outage of a single server. Further, it’s also simple to use and simple to scale, making it ideal for enterprises that are consistently growing. At its core, Apache Cassandra’s structure is “built-for-scale” and can handle huge amounts of data and concurrent customers across a system. It lets major corporations store massive amounts of information in a decentralized system. Yet, despite the decentralization, it still provides customers to have control and access to data.
And, data is always accessible. With no single point of failure, the system provides true continuous availability, avoiding downtimes and information loss. In addition, because it can be scaled by simply adding new nodes, there is constant uptime and no required to shut the system down to accommodate more users or more information. Given these benefits, it’s not surprising that so many major organizations utilize Apache Cassandra.
Features of Cassandra:
Some of the most Important features were discussed below:
•Elastic scalability: Cassandra is highly scalable; it offers to add more hardware to accommodate more users and more information as per need.
•Always on architecture: It has no single point of failure and it is continuously available for business-critical apps that cannot afford a failure.
•Fast linear-scale performance: This is linearly scalable, i.e., it enlarges your throughput as you enlarge the number of nodes in the cluster. Therefore it maintains a quick response time.
•Flexible data storage: It accommodates all possible data formats including: structured, semi-structured, and unstructured. It can dynamically accommodate changes to your data structures according to your requirement.
•Easy data distribution: This offers the flexibility to distribute information where you require by replicating information across multiple data centers.
•Transaction support: This tool assists properties such as Atomicity, Consistency, Isolation, and Durability (ACID).
•Fast writes: It was designed to run on cheap commodity hardware. It performs blazingly fast writes and can store hundreds of terabytes of data, without sacrificing the read efficiency.
Latest Innovations:
One of the most exciting features of Java 11 is the new Z Garbage Collector(ZGC) that aims to decrease GC pause times to a max of a few milliseconds with no latency degradation as heap sizes increase. This characteristic is still experimental and thorough testing should be performed before deploying to production. These improvements significantly enhance the node availability profiles from garbage collection on a cluster which is why this feature has been included as experimental in the Cassandra 4.0 release.
Market Share:
Cassandra has a market share of 7.94% in no-sql databases market. There are so many opportunities for this tool. A Cassandra Admin is paid around Rs.1,020,000. You can opt for this course as a career enhancement. Cassandra Administration online training by GoLogica gives knowledge of all topics through effective exercises.
