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

"The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount."
"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 most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."
"The most valuable features are the counter features and the NoSQL schema. It also has good scalability. You can scale Cassandra to any finite level."
"I'd rate the solution ten out of ten."
"The principal advantage of Couchbase for us is that we can have multiple database paradigms in the same product, without deploying multiple databases."
"I can input any kind of document into the solution and it is integrated using a dynamic API. This has been the most valuable aspect of using this solution."
"The most valuable features of Couchbase include the key-value storage due to its speed and the multi-master capability, which provides more speed and scalability compared to master-slave databases."
"The main advantages were associated with it being a no SQL database. It helped us send out metrics or rewards to multiple players in our game at a very low latency."
"Couchbase was a stable solution for us."
"The valuable features of Couchbase are the many documents and index types, and they made a lot of features available enabling us to use it as a complete solution for our needs."
"Couchbase has not given any performance problems as of now."
"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%."
"The most valuable feature is the geometric information done with GeoJSON."
"We chose MongoDB because of its community."
"The geospatial index feature is useful for dealing with latitude and longitude data."
"The tool is also user-friendly."
"MongoDB is relatively fast compared to relational databases."
"In our case, it is most important to have redundancy."
"MongoDB is cool; there is a difference between relational databases and newer databases like MongoDB, and MongoDB is scalable and fast."
"The clustering is very good. It allows us to have high availability."
 

Cons

"One of the issues with the solution is that you cannot drop write like you're able to in MongoDB and MySQL, where you can join tables."
"Cassandra could be more user-friendly like MongoDB."
"Fine-tuning was a bit of a challenge."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"There could be more integration, and it could be more user-friendly."
"Interface is not user friendly."
"The disc space is lacking. You need to free it up as you are working."
"Row-level locking is not available; might be very helpful in update use cases."
"Needs some capacity planning to deal with too much memory, CPUs and displays."
"The failover and failback could be a bit easier. When I looked at it last time, it had to be manually done, and it also took over an hour for us to rebalance all the nodes."
"I would like Couchbase to provide more functionality via the UI, as some operations, such as time-based scaling, currently require using the API."
"The platform's grouping features need improvement."
"It's easy to deploy. Where the challenge comes in is when you start putting data in, doing the indexes, and doing the integration with systems. Integration is one of their weakest points. Natively, there should be a wide range of integration options to be able to get data in."
"Couchbase Enterprise can improve by being a little lighter for use cases as it requires heavy customization."
"The failover and failback could be a bit easier. When I looked at it last time, it had to be manually done. It also took over an hour for us to rebalance all the nodes."
"When I faced issues with Couchbase Enterprise, the community support was not strong."
"I think that MongoDB's search engine should be improved."
"The stability could be better."
"Simplifying the aggregation framework would be an improvement."
"I have found the solution difficult to operate as an administrator."
"From my point of view, they need a totally free IDE to work at high levels."
"The performance could be faster."
"It could be much more flexible like SequoiaDB. I would like to see more flexibility in the next release, especially when working with Microsoft Windows."
"MongoDB would be improved with more integration, particularly for cloud environments like Google BigQuery."
 

Pricing and Cost Advice

"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."
"I don't have the specific numbers on pricing, but it was fairly priced."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"We pay for a license."
"I would rate this solution a nine out of ten for pricing as it is affordable."
"It can range between 25,000 to 40,000 Euros per year depending on company requirements."
"The licensing cost of Couchbase is quite expensive compared to other databases."
"I wouldn't say Couchbase offers good value for money."
"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."
"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."
"The price of this solution is better than some of the other competitors."
"The pricing is favorable if you opt to install MongoDB on an Amazon EC2 instance as you won't have to pay for the extra Atlas services and can instead manage the scaling yourself. This allows for a cost-effective solution and using MongoDB on a small scale, I have been able to utilize it for free."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"Our customers pay for yearly licenses for MongoDB."
"You only have to pay for the paid version, not the open-source version."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"MongoDB is a bit expensive compared to its competitors."
"The pricing is normal. Price-wise, the product is not too much expensive."
