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.

High availability for large billing data has supported telecom orders but monitoring still needs work

Since working with Couchbase Server starting from version 6, where only scopes and collections were available, I have seen numerous improvements with the release of version 7, especially as bugs identified in version 6 were addressed by the Couchbase Server team. One specific outcome I have noticed is identifying constraints such as not being able to create more than thirty buckets, which we notified the Couchbase Server team about, along with several missing monitoring parameters; they worked with us to provide better solutions in terms of monitoring and the metrics we require for our production monitoring setups, ensuring our production is up and running smoothly. Regarding improvements, I feel that the current dedicated monitoring, such as CMX offered by Couchbase Server, requires enhancements for better identification of issues, especially since the market is moving towards AI-driven solutions, and I believe Couchbase Server is working on improving its AI capabilities. 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. Regarding the accuracy and reliability of Couchbase Server's AI capabilities, I perceive there are gaps since the tools are not being developed maturely and require more developed solutions for our agent workflows to facilitate automation with AI agents.

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 the NoSQL database, high performance, and zero-copy streaming."

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

"I am satisfied with the performance."

"We can add almost one million columns to the solution."

"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."

"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."

"The solution provided us with more than 100K PNRs a second and because the company was international there was a heavy data write, and at the same time a heavy data read."

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

More Cassandra pros

"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."

"I would advise others considering Couchbase Server to note that compared to other tools such as MongoDB, it is easier to use, reliable, and offers high availability while continually adding more features, making it a suitable choice, especially for large data environments."

Cons

"Row-level locking is not available; might be very helpful in update use cases."

"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."

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

"The solution doesn't have joins between tables so you need other tools for that."

"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 clustering needs to be better; it is getting there."

"There could be more integration, and it could be more user-friendly."

"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."

More Cassandra cons

"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."

Pricing and Cost Advice

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

"We pay for a license."

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."

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

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

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