Executive SummaryUpdated on Mar 15, 2026

ScyllaDB and Redis are prominent contenders in the high-performance database arena. While ScyllaDB presents a comprehensive suite of features appealing to enterprises in need of robust data handling and speed, Redis's simplicity and efficiency give it an edge for those seeking ease of use and rapid retrieval.

Features: ScyllaDB stands out with its user-defined types, enabling consistent data handling at high speeds even with heavy loads. It facilitates seamless integration with the Cassandra SDK and migrations from DynamoDB. Its capabilities in high availability and partitioning make it ideal for enterprise environments. Redis, renowned for ease of use, excels in fast retrieval speeds and efficient caching. Its in-memory storage minimizes latency and offers powerful real-time performance with strong integration across platforms.

Room for Improvement: ScyllaDB could enhance its user experience with more user-friendly documentation and setup, focusing on reducing Java dependency. Challenges in data handling, particularly deletions, affect performance. Redis's single-threaded architecture creates a single point of failure and lacks GUI applications and schema validation. Its documentation could improve, alongside enhanced security measures and scalability guidance.

Ease of Deployment and Customer Service: ScyllaDB offers various deployment options, including on-premises and hybrid cloud setups. Its customer service is responsive, though critiques include high costs for personalized support and setup complexities. Redis shows flexibility in deployment with public and hybrid cloud options, though it lacks specialized guidance for intricate queries, yet remains attractive for cost-sensitive deployments due to its free nature.

Pricing and ROI: Despite a high price for enterprise features, ScyllaDB is considered a worthwhile investment if it aligns with business returns. The enterprise support, while costly, delivers robust guidance. Redis, open-source and minimizing licensing expenses, incurs some infrastructure costs but is cost-effective for both small-scale and extensive uses, enhancing its economic appeal across various scenarios.

Caching has improved response times and reduces database load for high-traffic applications

Redis is very reliable, but it could be improved in areas such as monitoring, debugging, and feasibility into memory use. Better built-in tools for observability would help teams manage it more effectively at scale. Managing memory efficiently and troubleshooting issues can sometimes require additional tooling, so these areas can also be improved.One practical challenge I experienced is managing memory efficiently. Since Redis is in-memory, we need to carefully configure eviction policies and monitor usage. Debugging cache-related issues such as stale data or cache invalidation can sometimes be tricky. Additionally, tuning memory usage and eviction policies needs to be planned very carefully.

Reliable data management with great reliability and performance

From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction. Additionally, ticketing and support systems could be improved due to the time it takes to get answers. There's also an issue with compatibility when attempting to switch back from the enterprise to the community version.

Quotes from Members

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

Pros

"Redis provides an easy setup and operation process, allowing users to quickly connect and use it without hassle."

"Overall, Redis helps us design more efficient applications by improving performance while allowing our backend services to scale more effectively."

"Redis is a simple, powerful, and fast solution."

"Redis is good for distributed caching management."

"The solution is fast, provides good performance, and is not too expensive."

"The performance of Redis is very fast."

"Redis acts as an in-memory search tool that improves the speed of operations, allowing for quicker data retrieval and enhancing the performance of applications."

"The in-memory data makes it fast."

More Redis pros

"Scalability in performance is good."

"The performance and scalability are good, and we hardly see any major issues with ScyllaDB."

"The best features of ScyllaDB are how it synchronizes data and its failover system. There's a unique formula to decide the number of nodes you need and the minimum required, which I find helpful. It also offers encryption and supports APIs, making it great for distributed systems and scaling databases across different regions. While it's easy to use, having prior experience helps configure it properly. There are many configurations; if you don't understand them, you might mess up the design. So, understanding your system's needs, like whether it requires more read or write operations, is crucial for setting up the correct configuration."

"ScyllaDB is fast and reliable. It has good performance."

"The documentation is good. It integrates easily with our existing data infrastructure."

"It is lightweight, and it requires less infrastructure."

"The product's most valuable features are efficiency and reliability."

"The database is easy to use, fast, and accessible for applications because the API is straightforward."

More ScyllaDB pros

Cons

"There is a lack of documentation on the scalability of the solution."

"The only thing is the lack of a GUI application. There was a time when we needed to resolve an issue in production. If we had a GUI, it would have been easier."

"I would prefer it if there was more information available about Redis. That would make it easier for new beginners. Currently, there is a lack of resources."

"Redis presents a single point of failure and lacks fault tolerance."

"The initial setup of Redis was difficult, with a rating of two or three out of ten."

"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."

"The disadvantage of Redis is that it's a little bit hard to have too many clusters or too many nodes and create the clusters."

"The first challenge is memory limitations, as Redis is primarily in-memory, making memory usage a key constraint."

More Redis cons

"If you don't have the best computing resources, then it's not easy to set up. In such cases, we have to run ScyllaDB in developer mode."

"The product needs to add more features and improve the response time of the support team."

"We've had occasional performance challenges that required resource adjustments or optimizations in our interaction with the platform."

"Support and the availability of support need improvement. I would give them a six out of ten."

"It seems we have better options available. So probably don't go for ScyllaDB. The reason is, first, it's very high. It's not as straightforward as, like, Postgres or ClickHouse to set up. It requires a complex setup."

"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."

"Data export, along with how we can purchase the data periodically, needs to be improved so that the storage is within control. Then, we could optimize it even better."

"The documentation of Scylla is an area with shortcomings and needs to be improved."

More ScyllaDB cons

Pricing and Cost Advice

"The tool is open-source. There are no additional costs."

"Redis is an open-source solution. There are not any hidden fees."

"Redis is an open-source product."

"Redis is not an overpriced solution."

"We saw an ROI. It made the processing of our transactions faster."

"It's free."

"The paid version of ScyllaDB is not that expensive. The main advantage of the paid version is direct support from the ScyllaDB team, which can resolve issues faster—typically within a day, compared to two to three days with the free version. The paid version also offers better guidance and support, while the free version has good documentation and is more high-level. I’d rate their support team nine out of ten because of the quick responses from their community."

"I believe that there is a yearly licensing cost and that it's expensive."

"It's a bit expensive."

"It is an expensive tool compared to its competitor."
