Important considerations

Pros

  • Scalability: Cassandra is a highly scalable system, allowing for horizontal scaling with an easy-to-use architecture. It can handle massive amounts of data in a distributed environment.
  • High Availability: Cassandra is designed for continuous availability, protecting data with no single point of failure and providing high performance even in the face of nodes going down or becoming unavailable.
  • Flexibility: Cassandra allows for flexible data modeling, allowing users to easily create and modify applications without having to modify the underlying data structures.
  • Security: Cassandra provides robust security, allowing for authentication and authorization across the cluster, as well as encryption of data at rest.
  • Multi-Data Center Support: Cassandra includes multi-data center support, allowing for data to be replicated and synced across multiple data centers.

Cons

  • Learning Curve: Cassandra can be difficult to learn, especially for developers who are new to NoSQL databases.
  • Hardware Requirements: Cassandra requires a large amount of memory and storage capacity to perform properly.
  • Stability Issues: Cassandra is known to be less reliable than other popular NoSQL databases, such as MongoDB.
  • Lack of Support: Cassandra has limited support, with few third-party vendors providing services or tools.
  • High Cost: Cassandra can be expensive to implement and maintain, with licensing costs and hardware requirements adding up quickly.

Common questions

  1. What is Cassandra? Cassandra is a distributed NoSQL database system designed to handle large amounts of data across multiple servers.
  2. Does Cassandra have an SQL interface? No, Cassandra does not have an SQL interface. Cassandra's query language is CQL (Cassandra Query Language).
  3. What are the advantages of using Cassandra? The advantages of using Cassandra include scalability, high availability, and strong data consistency. Additionally, Cassandra has a flexible data model, fast writes and reads, and is easy to operate.
  4. Does Cassandra run on Linux? Yes, Cassandra runs on Linux, macOS, and Windows.
  5. What is the cost of Cassandra? Cassandra is open-source software, meaning it is free to download and use. However, there are commercial versions available from DataStax and other vendors that come with features like dedicated customer support and enhanced security.
  6. Does Cassandra work with AWS? Yes, Cassandra is compatible with Amazon Web Services (AWS). DataStax and other vendors provide Cassandra-as-a-Service (CaaS) solutions that run on AWS.
  7. What types of applications can Cassandra be used for? Cassandra can be used for many types of applications, including web applications, Internet of Things (IoT) applications, and real-time analytics.

Trivia

Cassandra is well known for its ability to reliably handle data and keep it available even when nodes in the cluster fail. However, there is a funny story about a time when it didn't quite work out as planned. In 2018, the hosting company OVH suffered an outage due to a power failure in a data center, which brought down a Cassandra cluster with over 4.5 million nodes. Although Cassandra is designed to be resilient in the face of hardware failures, it wasn't quite enough to prevent the entire cluster from going down. Fortunately, it was quickly brought back up, but it was a humorous reminder that even the most reliable databases can succumb to unexpected events.
