Understanding the basics of Apache Cassandra
Apache Cassandra is the scalable NoSQL database that powers global businesses like Spotify, Netflix, and Apple. Apache Cassandra is a NoSQL, or “non-relational,” database. In today’s world, many online applications have database requirements that exceed the capabilities of traditional databases. Non-relational databases were created to meet these requirements. They have very low latency, and can adapt to unknown levels of scale while providing “continuous uptime, global distribution of data, and the ability to both write and read data anywhere,” which reduces software and operational costs. Apache Cassandra is considered a non-relational database because it provides “a massively scalable open source database offering continuous availability, linear scale performance, operational simplicity, and easy data distribution across multiple data centers and cloud availability zones.”
Cassandra’s “ring” architecture is masterless, meaning all nodes play an identical role instead of having one master node. These nodes communicate with each other via a “distributed, scalable protocol called ‘gossip.’” This architecture is specifically designed for scale, and it is capable of “handling large amounts of data and thousands of concurrent users or operations per second just as easily as it can manage smaller amounts of data and user traffic.” The ring architecture also means that there is no single point of failure, meaning availability and uptime can be truly continuous.
These features make Apache Cassandra a popular choice for enterprises looking for both scalability and high-availability without compromising performance. Since all nodes in Cassandra’s architecture design are the same, enterprises can create databases that are both massively scalable and operationally simple. It’s flexible and dynamic data model easily supports modern data types, and data can be compressed up to 80% without compromising performance. The ability to scale by adding nodes into an existing ring without having to take it down first allows for predictable increases in performance that can be replicated across multiple data centers.
The Cassandra database is especially useful for enterprises developing internet of things applications, messaging platforms, and social media analytics and recommendation engines. Media companies, like Spotify, use Cassandra to track and monitor the activity of their users’ activity and interactions on their applications so they can tailor content recommendations to each specific user. Cassandra is also a popular choice for online retailers looking to provide customers with reliable shopping cart security and retail app support.
Datapipe supports NoSQL database deployments for our clients, and offers an enterprise grade, production ready Apache Cassandra offering, which can be supported on AWS and Azure or in a hosted private cloud environment.
