It’s no secret that businesses have a love-hate relationship data. It can lead to unguided decisions and market data are lost when companies gather too little information. However when you have active and large data sets, where the number of requests is in hundreds or thousands ensuring that databases perform at a high level becomes increasingly difficult.
One open source program, Apache Cassandra, enables organizations to process huge amounts of data that are moving fast with a reliable and efficient way. This is why companies such as Facebook, Instagram and Netflix utilize Apache Cassandra for mission-critical features. Let’s examine three key advantages, drawbacks and usage instances from Apache Cassandra, and the most straightforward method of getting it working in production.
What exactly is Apache Cassandra?
To begin an overview of the database – Apache Cassandra is a database which is focused on reliability as well as speed and scaling. It is able to store massive volumes of data that is incoming and handles several hundred thousand writing per second.
Cassandra helps organizations to manage massive quantities of data in a short time – offering the benefits listed below for its users.
The top 3 advantages of making use of Cassandra
Speed – Performance
Specific architectural options Certain architectural decisions make Cassandra an ideal technology for processing data at a much faster rate than alternatives to databases. There are two methods Cassandra can achieve a speedy processing:
It takes quick decisions about how to store data. It does this by through an algorithm that hashs data
It allows any node make storage decisions for data. This removes the necessity for an uncentralized “master node” which needs to be consulted for storage decisions.
Scalability
Cassandra is extremely scalable, and can be increased in performance simply by installing a rack. In the first place, there isn’t a “master” which needs to be enlarged to manage data and orchestrate it. That means that all nodes are able to be less expensive and common servers.
In addition, it increases scaling by placing less emphasis upon data quality. Consistency usually requires a master node in order to determine and control the definition of consistency using rules or data that has been stored previously.
It also uses peer-to-peer communication, using the cleverly called “gossip protocol”. It allows nodes to communicate and share metadata between them, making the process of creating new nodes extremely simple.
Reliability – Data replication and the ability to replicate data
It’s also a reliable storage of data. The algorithm for hashing stores information as well as creates backups of it and puts them into various places. If the node is down and Cassandra is able to make the reasonable assumption that eventually it will fail it will have a backup of it.
Relaxing consistency is the way to achieve this. Traditional databases have to be extremely thoughtful (and slow) when it comes to replicating data since there must be an approach to ensure that different copies of the same data are up-to-date.

The challenges of making use of Apache Cassandra
Rapidity, scalability, and durability cost money. The choice of availability over consistency is made in Apache Cassandra so it is possible that data could contradict. When it attempts to validate information over time, the system may be slow in doing this. This can slow down the process of reading the information that is already stored. The database must look through all the data it has stored, which includes several entries for the same data that could be contradictory.

The above outline highlights the advantages and drawbacks to Apache Cassandra but how does it fit into your system? We have listed some common applications:
Data from time-series: Cassandra has a great record of storing time-series information, in which the data doesn’t need to be modified. A good example of this is log files that are stored on cloud infrastructure and applications. There’s no need to modify a log once it’s been saved. If it’s not correct it’s easier to check the latest, more accurate version and then store it with a more recent timestamp.
Globally distributed data geographically distributed data in which local Cassandra cluster can be used to store data, which can then be synchronized in later times. Since it does not have a “master node” and it is able to be scaled with commodity storage which is cheap, it allows expanding the geographic area of the database
Network costs are very high. Cassandra can be an effective cost-effective solution when networks (e.g. shifting data across data centres) costs are very high as it doesn’t have to send data continuously to a distant master node.
Clouds for organizations can be modernized and change the way data is stored and processed by using Cassandra. This allows you to manage massive quantities of data across the globe.
Summary
Apache Cassandra lets your cloud reach “hyper-scale”. It gives practical solutions to achieve speeds, capacity, and availability required for hundreds of millions of write per second.
