Executive SummaryUpdated on Jan 7, 2025

Cassandra and Oracle NoSQL are competitive in managing large data volumes. Cassandra is preferred for scalability and robust data replication, whereas Oracle NoSQL stands out for its comprehensive analytics features.

Features: Cassandra offers high availability, linear scalability, and robust data replication, making it suitable for large-scale, fault-tolerant applications. Oracle NoSQL provides comprehensive analytics, seamless integration with Oracle products, and advanced features for transactional applications.

Room for Improvement: Cassandra can be complex to optimize, especially for users without significant expertise. Improvements could focus on enhancing user-friendliness, expanding support options, and improving integration capabilities. For Oracle NoSQL, enhancements could include reducing costs, increasing scalability for non-Oracle ecosystems, and improving open-source flexibility.

Ease of Deployment and Customer Service: Cassandra allows flexible deployments both on cloud and on-premises but might need expertise for optimization. Oracle NoSQL benefits from Oracle’s structured deployment and support network, simplifying implementation and troubleshooting.

Pricing and ROI: Cassandra, being open-source, has lower initial costs and offers higher ROI for budget-conscious users. Oracle NoSQL has higher upfront costs offset by extensive support and features, possibly delivering better long-term ROI.

Has maintained secure document storage and efficient data distribution with peer-to-peer architecture

The functions or features in Cassandra that I have found most valuable are that it is a distributed system similar to Mongo. It's good enough for comparison with another SQL database, so it's smooth and organized for distributed database system. The peer-to-peer architecture in Cassandra is helpful for network decentralization, and I have already introduced that feature. Cassandra features in peer-to-peer as well as another monitoring, so basically, it's good enough for our service. The tunable consistency level in Cassandra is good, and we are using that feature already. In terms of built-in caching and lightweight transactions in Cassandra, the transaction level is good, and it's optimized, so there are no more issues in that database. Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there. Additionally, the database monitoring system or auditing system is well-comparable with other database systems, so we are actually happy to be using this Cassandra database.

Handles large data volumes effectively but connection issues require attention

The Oracle NoSQL solution is used primarily for storing data for our web applications. We work alongside the DBA team for this purpose, given that specific departments manage aspects of its use. We choose it specifically to handle large scales of data, such as in one of our bank customer's scenarios using more than nine hundred gigabytes of data.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."

"The time series data was one of the best features along with auto publishing."

"The solution provided us with more than 100K PNRs a second and because the company was international there was a heavy data write, and at the same time a heavy data read."

"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."

"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."

"The most valuable features of this solution are its speed and distributed nature."

"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."

"I am getting much better performance than relational databases."

More Cassandra pros

"With Oracle NoSQL, our clients have a highly scalable, simple to set up database that performs very well when data is organized correctly from the beginning."

"The tool is easy to learn."

"Oracle NoSQL is pretty scalable."

"We have a support agreement with Oracle, ensuring full support for the product. It is crucial for our public-facing features. Oracle NoSQL is easy to manage and has fast data retrieval. Its compatibility with Oracle Database is seamless, making integration between NoSQL and relational databases smooth and effortless. Oracle NoSQL and NoSQL data replication in our environment works efficiently. Oracle fully supports it, and we can easily configure and manage authentication for the NoSQL database."

"NoSQL has high availability; I think it's perfect from a technical perspective, and it's quick to run and go."

"The product meets expectations when it comes to stability."

"The features I've found to be most valuable are the speed of reading and writing (read/write performance levels are really high), the transactions model (semantics for data manipulation), and just the overall simplicity of using it."

"Try it! You’ll be impressed."

More Oracle NoSQL pros

Cons

"Row-level locking is not available; might be very helpful in update use cases."

"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."

"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."

"The initial setup of Cassandra can be difficult in the configuration. There might be a need to have assistance. The implementation process can six months for connecting to certain databases."

"While Cassandra can handle NoSQL, I think there should be more flexibility for whole schema design when data is stored in wide columns. Additionally, I believe that eventual consistency should be enhanced."

"There could be more integration, and it could be more user-friendly."

"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."

"It can be difficult to analyze what's going on inside of the database relative to other databases. It can also be difficult to troubleshoot sometimes."

More Cassandra cons

"Oracle could improve how NoSQL works in containers. I don't think NoSQL needs any new features, but I want to see new features in the Oracle Cloud Infrastructure. I would like to see some improvements in OCI's building options."

"Handling big data in a user-friendly way is currently a bit of an issue. The dashboard for this needs some work."

"Personally, I’d like to see some improvements in the monitoring UI for it."

"The installation is difficult."

"We've had some issues with stability. During our testing, we were able to drop an entire database by writing huge amounts of data."

"Focusing on making the administration easier compared to other solutions like MongoDB could be beneficial. Simplifying the administrative tasks could enhance the user experience."

"You will get high performance when you organize your data correctly at the beginning. Otherwise, there are instability issues."

"The main areas that need improvement with NoSQL are in the area of big data and user-friendly presentation."

More Oracle NoSQL cons

Pricing and Cost Advice

"We pay for a license."

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."

"We are using the open-source version of Cassandra, the solution is free."

"I don't have the specific numbers on pricing, but it was fairly priced."

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."

"I use the tool's open-source version."

"The product is expensive and Oracle could work to lower the licensing cost."
