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.

Lead Software Engineer at a tech vendor with 10,001+ employees

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.

Quotes from Members

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

Pros

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

"Cassandra is a stable solution."

"Can achieve continuous data without a single downtime because of node to node ring architecture."

"The technical evaluation is very good."

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

"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."

"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."

"Since I haven't had years of experience with it, it's still new to me. One valuable feature is its distribution, so I can run it partly in the cloud and part on-prem. That's a feature I'd like to use but haven't yet because we're trying to move to Azure. I don't know if or when that will happen. Ideally, we'd have it distributed over the cloud and on-prem simultaneously, so if something happens to our on-prem, we can keep going in the cloud, like a pay-as-you-go model with Azure."

More Cassandra 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."

"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."

"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."

"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."

"I primarily use Couchbase Server for cache because this cache is very useful and the performance is excellent."

"Couchbase Server has positively impacted my organization as we have significantly used it in most of the applications."

More Couchbase Server pros

Cons

"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."

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

"We have had stability issues including out of memory issues and crashes with earlier versions of the product."

"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."

"Batching bulk data can cause performance issues."

"It can be difficult to analyze what's going on inside of the database relative to other databases. It can also be difficult to troubleshoot sometimes."

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

"The disc space is lacking. You need to free it up as you are working."

More Cassandra 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."

"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."

"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."

"We could use hyperscale vector indexing and upgrade the storage engine so that density and throughput would be higher."

Pricing and Cost Advice

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

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

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

"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."

"We pay for a license."
