A backend developer is already familiar with the Cassandra database. One of these databases has good speed and scalability.
One of the most popular databases in the world known for its good speed and scalability is the Cassandra database. These advantages have placed it on the list of the top 10 most widely used database engines. So, what are its other advantages and components?
Definition and Brief History of Cassandra Database
The Cassandra database is also known as Apache Cassandra. It is defined as an open-source system that distributes and manages large-scale structured data. This NoSQL database does not use table relationships and stores data in rigid tables. Therefore, it is a suitable choice if you need high scalability and availability. Its ability to store large amounts of data is unquestionable. This open-source system serves as a support for improving businesses. Initially, Cassandra was developed at Facebook to power the inbox search feature. Its architecture combines a distributed model and enables horizontal scaling.
What Are the Features of the Cassandra Database?
There are four features in Apache Cassandra that will amaze its users. Telkom University attempts to explain these four features, including:
Elastic Scalability
Apache Cassandra allows for the addition of storage capacity at any time without being bound to the same hardware or location.
Flexible Data Storage
Cassandra can accommodate all formats, including dynamically structured data. Moreover, this open-source system can accommodate changes in data structure as needed.
Easy Data Distribution
Cassandra also provides flexibility in distributing data as needed. It does so by replicating data in data centers. The data is replicated into multiple nodes. When an error occurs, the node is immediately replaced.
Fast Writes
Cassandra has been designed to run on hardware, allowing it to write quickly and store hundreds of terabytes of data.
Completing Components
In addition to its features, Cassandra is equipped with several main components, such as:
- Node: The place to store data.
- Data center: A collection of several nodes.
- Cluster: A collection of several data centers.
- Commit log: The process of writing in Cassandra.
Having the Cassandra database will help servers perform well because it has powerful features and main components.
