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 offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."

"Can achieve continuous data without a single downtime because of node to node ring architecture."

"Our primary use case for the solution is testing."

"A consistent solution."

"Some of the valued features of this solution are it has good performance and failover."

"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."

"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 solution's database capabilities are very good."

More Cassandra pros

"Oracle NoSQL is pretty scalable."

"The tool is easy to learn."

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

"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."

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

Cons

"The solution is not easy to use because it is a big database and you have to learn the interface. This is the case though in most of these solutions."

"Some issues arise from our vendors like Apache slowness and distribution or load balancing from HAProxy, which should better handle consumption for high-level concurrency."

"I want Cassandra to update its open-source version more quickly. It's already feature-rich, but I'd appreciate better integration with other NoSQL databases like MariaDB or MongoDB. If I ever need to work with customers or vendors using different NoSQL databases, having native integration in Cassandra would make managing and interacting with their databases much easier."

"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."

"Maybe they can improve their performance in data fetching from a high volume of data sets."

"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."

"Batching bulk data can cause performance issues."

"Cassandra could be more user-friendly like MongoDB."

More Cassandra cons

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

"I would rate Oracle NoSQL six or 6.5 out of ten based on my experience."

"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."

"The installation is difficult."

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

Pricing and Cost Advice

"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."

"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."

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

"We pay for a license."

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

Overview

Cassandra is a distributed and scalable database management system used for real-time data processing.

It is highly valued for its ability to handle large amounts of data, scalability, high availability, fault tolerance, and flexible data model.

It is commonly used in finance, e-commerce, and social media industries.

Apache

The Oracle NoSQL Database (ONDB) provides network-accessible multiterabyte distributed key/value pair storage with predictable latency. Data is stored in a very flexible key-value format, where the key consists of the combination of a major and minor key (represented as a string) and an associated value (represented as a JSON data format or opaque set of bytes). It offers full Create, Read, Update and Delete (CRUD) operations, with adjustable durability and consistency guarantees. It also provides powerful and flexible transactional model that eases the application development.

The Oracle NoSQL Database is designed to be a highly available and extremely scalable system, with predictable levels of throughput and latency, while requiring minimal administrative interaction.
