Cassandra Reviews

Cassandra offers a free open-source version, but enterprises using it for major production often opt for DataStax Enterprise, incurring costs for licensing and support. Support costs can reach approximately $50,000 annually. Licensing may be annual or monthly, with regional price variations, particularly in regions like the UAE. The commercial version demands budgeting for potential maintenance and support, while open-source users benefit from negligible to no costs, aside from homegrown efforts.

• "I use the tool's open-source version."
• "I don't have the specific numbers on pricing, but it was fairly priced."
• "We pay for a license."

Users employ Cassandra for various purposes such as designing data models for product catalogs, running analytics on large datasets, and managing IoT projects for high-performance runtime databases. They utilize it for key management in telecommunication, database management, and high-capacity memory-based tasks. Cassandra is favored for its database capabilities in cloud and on-premise environments, supporting high write workloads in applications like e-commerce, messaging systems, airline PNRs, and entity profiling.

Cassandra customers rely mainly on online resources and community forums for support since many use the open-source version. Some receive satisfactory assistance from vendors but feel that documentation could improve. While technical support from external sources is regarded as adequate, community support and response times might need enhancements. Some companies prefer local support due to regulatory compliance. Customers seek more accessible community support with detailed information, including specific use case instructions.

Many users found Cassandra's initial setup straightforward, aided by documentation and community support. For complex implementations, centralized tools or specialists were necessary, often requiring extensive configuration or coordination within larger teams. Deployments varied in duration, influenced by the complexity and specific scenarios. Some faced challenges in fine-tuning or when installation guidance was lacking. Automation scripts and online resources significantly eased the process for many, enabling efficient installations across various environments.

Cassandra is widely recognized for its robust scalability, praised for easy node addition and handling increased loads. Organizations utilize Cassandra for substantial projects, appreciating its efficiency in real-time data synchronization. Best suited for larger enterprises, it efficiently manages high write speeds and increased user demands. Teams highlight its usefulness for large-scale projects, enabling quick scaling. Despite minor potential for improvement, Cassandra consistently meets diverse data management requirements, making it a favorite among many developers and companies.

Cassandra is generally stable, with most experiencing good stability and performance. Users report issues with earlier versions, specific configurations, or when handling complex logic. While some encountered memory issues and occasional slowdowns, Cassandra performs well with large data sets. Stability can be dependent on certain configurations, but downtime is rare. Maintenance requirements exist but reduce once stability is achieved, with some needing multiple people for upkeep.
