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.

Integrated caching and SQL-style queries have improved real-time billing performance
Couchbase Enterprise can be improved by addressing the complex setup. The initial setup and configuration can be tricky and requires careful tuning of cluster settings, memory quotas, and indexes, which I have already faced. Another area for improvement is the learning curve. Although N1QL is powerful, there is still a learning curve, especially for developers coming from traditional relational databases. The licensing cost is something to consider as well. Enterprise licensing can be expensive and may not be ideal for startups or smaller organizations. There is operational overhead with Couchbase Enterprise, such as managing clusters, monitoring performance, and handling failovers, which require strong DevOps expertise. It would be better if it simplified these aspects and provided better documentation.

Offers reliable engine for legacy needs but requires enhanced cost management and AI features
While MongoDB is a good product, it is also an expensive product for support, and its scalability is acceptable, but the big problem with MongoDB is the cost. For security in MongoDB, we work with encrypted databases by default, but we have not contracted the security options in our contract because it is too expensive, so we only implement encrypted databases without the security pack, which is very expensive for us; in security, we are at the first steps, just using encrypted databases. I think additional features needed in MongoDB include perhaps vector databases, as I think they are not supported right now.

Quotes from Members

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

Pros

"I'd rate the solution ten out of ten."
"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."
"The solution's database capabilities are very good."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"The technical evaluation is very good."
"The most valuable feature for us is the technical evaluation, it's the best technology."
"The most valuable features of this solution are its speed and distributed nature."
"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."
"I am very happy with this solution, and I would rate Couchbase a nine out of ten."
"Couchbase Enterprise has positively impacted my organization by making data querying faster, and real-time analytics is also done effectively."
"Couchbase Enterprise has positively impacted our organization by reducing latency by 60%; with its inbuilt cache, our performance improved significantly by 50%, and the time taken to search in Couchbase was also reduced, leading to an overall performance improvement of 78.3%."
"It can scale horizontally, and we are looking to expand our capacity."
"Couchbase Enterprise has positively impacted my organization by being easy to set up and use, making the GUI perfect for everyone, which enhances user experience."
"I rate Couchbase a nine out of ten."
"The most valuable features are the ease of application and the merging of data."
"The principal advantage of Couchbase for us is that we can have multiple database paradigms in the same product, without deploying multiple databases."
"I like its performance and the stability; it's very stable and, performance-wise, it's really great."
"It is convenient to use because we can do manipulations with the JSON data that we get. There are also a lot of joins and associations with MongoDB, which makes it easy to use for us."
"My advice for anybody who is considering MongoDB is that when we want to have flexibility in storing our data, I recommend using it."
"It is very fast - faster than an SQL or MySQL Server."
"MongoDB is a solution that I can recommend because we have realized good benefits from it."
"The solution is stable and the performance is good."
"It can handle a lot of files quickly."
"One of the most valuable features is the ability to Text Search can be used anywhere and anytime."
 

Cons

"While Cassandra can handle NoSQL, I think there should be more flexibility for whole schema design when data is stored in wide columns. Additionally, I believe that eventual consistency should be enhanced."
"The initial setup of Cassandra can be difficult in the configuration. There might be a need to have assistance. The implementation process can six months for connecting to certain databases."
"The solution is not easy to use because it is a big database and you have to learn the interface."
"There could be more integration, and it could be more user-friendly."
"The secondary index in Cassandra was a bit problematic and could be improved."
"Batching bulk data can cause performance issues."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"The solution doesn't have joins between tables so you need other tools for that."
"Needs some capacity planning to deal with too much memory, CPUs and displays."
"There are some limitations to the database. The SQL database cannot handle real-time processing for critical IoT scenarios. What we have to do is store our data into the database then code it out, this wastes a lot of time."
"The performance could be quicker and better, especially in the querying process."
"The platform's grouping features need improvement."
"The UI I am using is not very user-friendly."
"Couchbase Enterprise can be improved by addressing the complex setup. The initial setup and configuration can be tricky and requires careful tuning of cluster settings, memory quotas, and indexes, which I have already faced."
"I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API."
"I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API."
"A normal Oracle or database tester will take some time to gear up to MongoDB because the way of writing queries is different in MongoDB."
"People coming from RDBMS should have the flexibility to write queries in SQL that can be converted into JSON queries."
"It should have GUI for managing clusters. MongoDB needs a more powerful GUI to manage clusters and make switchovers."
"It would be good to have scalability for clusters. For example, if we have three clusters, we should be able to increase to five clusters if required."
"MongoDB could improve by not having so many updates and different versions."
"It would be much more useful if I have an admin user and a password."
"The auto transaction feature is something that I found a little bit problematic. If we want to run two or three transactions at a time, we get write conflicts. So, it becomes really difficult when concurrency comes into the picture."
"The user interface is not as friendly as Oracle, which is something that can be improved."
 

Pricing and Cost Advice

"I don't have the specific numbers on pricing, but it was fairly priced."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"I use the tool's open-source version."
"We are using the open-source version of Cassandra, the solution is free."
"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."
"It can range between 25,000 to 40,000 Euros per year depending on company requirements."
"It seems very reasonable. It's a lot cheaper than Redis, but we've got an enterprise license. So, it's about normal. It's not outrageous in price as far as we've seen. From Couchbase, there's no additional fee as far as I'm aware, but when you're integrating, there's an additional fee because a lot of times, they don't have an integration stack."
"I would rate this solution a nine out of ten for pricing as it is affordable."
"The licensing cost of Couchbase is quite expensive compared to other databases."
"We estimate that it's not very expensive, however, the pricing that you can get from the account managers, e.g. the public pricing, could be a bit expensive."
"I wouldn't say Couchbase offers good value for money."
"The price of this solution is better than some of the other competitors."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"If you want support with the solution you will need to purchase a license and not use the open-source version. The license is a little expensive."
"I'm using the free version of MongoDB."
"MongoDB is a bit expensive compared to its competitors."
"The product is affordable."
"You only have to pay for the paid version, not the open-source version."
"MongoDB's pricing is reasonable."
"I only used the open-source version."
