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.

Performance shines with seamless session caching and minimal configuration

The best features of Redis, from my personal perspective, are the performance, which is very quick, and it's very simple to implement. Since I started using Redis, I feel that the product is saving me some performance tuning time. It's very easy, I have few parameters to tune, and it seems to have performance without a lot of working on the performance, compared to Cassandra, where you have to configure the memory and many other settings. The integration capability of Redis is excellent. Redis is very affordable because it's free.

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

"Since I started using Redis, I feel that the product is saving me some performance tuning time."

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

"What I like best about Redis is its fast and easy use. It has interesting algorithms like HyperLogLog and provides useful features. It's also good for implementing scalable rate limiting."

"Redis is good for distributed caching management."

"I use Redis mostly to cache repeated data that is required."

"The performance of Redis is very fast."

"The product offers fast access to my database."

"The in-memory data makes it fast."

More Redis pros

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

"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."

"ScyllaDB is very fast, and I can use it for so many things."

"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 allows fine-tuning of the table structure. Speed is probably the most critical factor because we perform a lot of heavy data ingestion. One of its core features is its ability to handle high volumes and maintain speed when accessing data. Additionally, high availability and partitioning are built-in features of ScyllaDB."

"Firstly, if I update something, it's most likely to finish within milliseconds."

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

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

More ScyllaDB pros

Cons

"There is room for AWS to provide more options for server types or a way to configure more or less memory for them."

"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."

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

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

"Redis should have an option to operate without Docker on a local PC."

"The development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."

"There are some features from MongoDB that I would like to see included in Redis to enhance its overall efficiency, such as the ability to perform remote behaviour. MongoDB is more efficient in handling updates than deletions and is quicker in processing updates, but it can be slower regarding deletions. This can sometimes pose a challenge, especially when dealing with large datasets or frequent data manipulations that involve deletions. In such cases, I often rewrite columns or update values instead of directly deleting data, as it can be more efficient."

"In future releases, I would like Redis to provide its users with an option like schema validation. Currently, the solution lacks to offer such functionality."

More Redis cons

"Some of the regular commands in NoSQL do not work."

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

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

"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."

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

"ScyllaDB needs to improve its handling of transactions."

"The documentation is not well established for new developers."

"We faced several challenges while integrating ScyllaDB into our AWS environment. One common issue was that a security port wasn’t opened on one node, preventingdata synchronization across clusters. We noticed the data wasn’t syncing correctly when we saw different record counts in other regions. After investigating, we found that the port was closed in one AWS region. Once we opened the port, the data synchronization across all nodes resumed as expected."

More ScyllaDB cons

Pricing and Cost Advice

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

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

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

"Redis is not an overpriced solution."

"Redis is an open-source product."

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

"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."

"It's free."

"It's a bit expensive."

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