Executive SummaryUpdated on Mar 5, 2025

Cassandra and SingleStore are competing in database management systems. SingleStore shows superiority in performance and scalability based on data comparisons.

Features: Cassandra offers a robust architecture with fault-tolerance, peer-to-peer design, and ensures seamless data distribution across multiple centers. SingleStore provides real-time analytics, in-memory processing, and superior speed with its SQL support and compatibility.

Room for Improvement: Cassandra requires improvements in configuration and setup complexity, query optimization, and is limited by read speed. SingleStore could enhance support for varied data models, reduce licensing costs, and increase integration options with other systems.

Ease of Deployment and Customer Service: SingleStore provides simplified deployment with cloud-native options and responsive support. Cassandra's deployment necessitates more configuration, lacking the ease found with SingleStore, and offers limited customer support.

Pricing and ROI: Cassandra's open-source model minimizes initial costs and offers an attractive ROI from lower setup expenses. SingleStore's premium pricing is offset by its enhanced performance and scalability, presenting increased long-term ROI potential.

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.

Real-time analytics has transformed daily decisions and delivers fast dashboards from streaming data

The best features SingleStore offers include fast data recovery and data compression by 80 percent. Having the information in sheets helps me to process the information quickly. Simplicity in T-SQL is another aspect I appreciate. Data recovery and sheet-based processing help my team on a day-to-day basis by enabling us to handle information efficiently. I would like to add that the data compression by 80 percent helps us in an excellent way since we are very fast in obtaining the data for our dashboards and the compression of the information is great. SingleStore has impacted my organization positively by enabling us to run low-latency analytics and model-driven use cases at scale, which is quite difficult for OLAP and OLTP databases alone. It has been very helpful because our internal clients are happy to have the data and make data-driven decisions easily. Making decisions based on data within a two-hour delay to the transactional database is excellent since we went from twenty-four hours to two hours. I think the best contribution is decision-making with data that is close to reality. Reducing that delay from twenty-four hours to two hours has significantly affected my team and business outcomes by increasing productivity. We have been able to serve all our customers, and they are very happy. We can deliver to them on time.

Quotes from Members

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

Pros

"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."

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

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

"The solution's database capabilities are very good."

"Cassandra is a stable solution."

"The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount."

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

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

More Cassandra pros

"MemSQL is a very powerful database."

"The product can automatically reinstall and reconfigure in case of a shutdown."

"SingleStore has impacted my organization positively by enabling us to run low-latency analytics and model-driven use cases at scale, which is quite difficult for OLAP and OLTP databases alone."

"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."

"It's a distributed relational database, so it does not have a single server, it has multiple servers. Its architecture itself is fast because it has multiple nodes to distribute the workload and process large amounts of data."

"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."

"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."

"SingleStore has impacted my organization positively because the output and performance of the app have been improved."

More SingleStore pros

Cons

"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."

"One of the issues with the solution is that you cannot drop write like you're able to in MongoDB and MySQL, where you can join tables."

"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."

"We found some issues with the batch inserts when the data volume is large."

"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."

"The solution is limited to a linear performance."

"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."

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

More Cassandra cons

"SingleStore can be improved in the aspect that the Azure pipelines do not have many parameterization features compared to others, for example, AWS."

"We don't get good discounts in Pakistan."

"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."

"Having the ability to migrate servers using a single command would be extremely beneficial."

"SingleStore is very well at the current stage, but I see room for improvement in ease of administration, monitoring, and reducing troubleshooting time."

"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."

"If you are going for self-managed, you need to set up a solid backup pipeline with SingleStore support, which was my only dissatisfaction, but after doing what was needed, we have very good backup and restore pipelines running, and in Helios, everything is perfect."

"For new customers, it's very tough to start. Their documentation isn't organized, and there's no online training available. SingleStore is working on it, but that's a major drawback."

More SingleStore cons

Pricing and Cost Advice

"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."

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

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

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

"We pay for a license."

"I would advise users to try the free 128GB version."

"The product's licensing is not expensive. It is comparable."

"They have two main options: cloud installation and bare-metal installation, each with different pricing models."

"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."

"SingleStore is a bit expensive."
