Modern AI workflows have become faster and data validation has supported complex microservices
We could use hyperscale vector indexing and upgrade the storage engine so that density and throughput would be higher. If Couchbase Server introduced natural language query capabilities, that would be helpful for everyone to use it in a more effective manner. The logging part could also be improved. Advanced security and logging would help us make the application more resilient. Couchbase Server is the best, but if natural language query capabilities were introduced, it would be easier for developers. Instead of writing queries, they could write using natural conversion language and give prompts to Couchbase Server, and they could get results in seconds.

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

"Couchbase Server positively impacts my organization as it serves as a crucial tool for my consulting services, allowing me to offer solutions to my clients' problems."
"Couchbase Server has positively impacted my organization as we have significantly used it in most of the applications."
"Couchbase Server is an absolute powerhouse for high-velocity modern enterprise applications and bridges the gap between flexible schema advantages of NoSQL and the rigid, trusted query capabilities of relational databases beautifully."
"Couchbase Server's primary benefit is that our data is in JSON form, and it is very fast in comparison to saving and retrieval with low latency."
"I primarily use Couchbase Server for cache because this cache is very useful and the performance is excellent."
"Couchbase Server provides us with more flexibility and a great cache."
"Couchbase Server is a high-performance NoSQL document database that we primarily use for caching and generative AI to develop modern applications using rapid data access and offline support for offline mobile applications, along with flexible data modeling."
"From knowing how Couchbase Server works and the performance outcome which I saw in real projects during battle testing and during anti-DDoS efforts, during my own project, I still keep using Couchbase Server and I am comfortable with it."
"It is lightweight, and it requires less infrastructure."
"ScyllaDB is very fast, and I can use it for so many things."
"I like how fast it is to query data from the ScyllaDB node!"
"The documentation is good. It integrates easily with our existing data infrastructure."
"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."
"The performance aspects of Scylla are good, as always... A good point about Scylla is that it can be used extensively."
"Firstly, if I update something, it's most likely to finish within milliseconds."
"ScyllaDB is fast and reliable. It has good performance."
 

Cons

"I am happy with the present support of Couchbase Server, but I would appreciate if customer support were more proactive and provided immediate responses."
"We could use hyperscale vector indexing and upgrade the storage engine so that density and throughput would be higher."
"Couchbase Server requires more enhancement, particularly with the MCP launched by Couchbase Server which is not yet fully functional and offers limited tools that are not beneficial for automating production workflows."
"To improve Couchbase Server, I believe they need more educational tutorials focused on developers, as understanding how to use it effectively is essential, and they should prioritize developer needs over sales perspectives."
"It would be great to have a kind of pub/sub in Couchbase Server."
"With one year of experience, I can suggest improvements for Couchbase Server."
"From a sales pitch standpoint, it needs to deliver on promises of better ROI and compaction."
"The product needs to add more features and improve the response time of the support team."
"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."
"Some of the regular commands in NoSQL do not work."
"The documentation of Scylla is an area with shortcomings and needs to be improved."
"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."
"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."
 

Pricing and Cost Advice

Information not available
"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 is an expensive tool compared to its competitor."
"I believe that there is a yearly licensing cost and that it's expensive."
"It's a bit expensive."
"It's free."
