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.

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

"We can add almost one million columns to the solution."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"The most valuable features of this solution are its speed and distributed nature."
"I am satisfied with the performance."
"Our primary use case for the solution is testing."
"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"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."
"The solution has good flexibility and very fast performance for searching data."
"MongoDB is simpler to learn and implement than traditional SQL solutions like MySQL."
"I found that MongoDB is most valuable for storing school-related queries. It's also user-friendly, and I found no difficulty accessing it. Setting it up is easy too."
"We are using real-time analytics and monitoring in MongoDB Enterprise Advanced; it is integrated—the existing advanced feature is integrated with our business analytics interface, and all the various business intelligence reports are generated from that."
"Sharding is an excellent feature of MongoDB."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"It can handle a lot of files quickly."
"MongoDB is cool. There is a difference between relational databases and newer databases like MongoDB. MongoDB is scalable and fast."
 

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 solution doesn't have joins between tables so you need other tools for that."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"Cassandra can improve by adding more built-in tools. For example, if you want to do some maintenance activities in the cluster, we have to depend on third-party tools. Having these tools build-in would be e benefit."
"Doesn't support a solution that can give aggregation."
"Some issues arise from our vendors like Apache slowness and distribution or load balancing from HAProxy, which should better handle consumption for high-level concurrency."
"The solution is not easy to use because it is a big database and you have to learn the interface. This is the case though in most of these solutions."
"We found some issues with the batch inserts when the data volume is large."
"There is room for improvement in integrating MongoDB with agentive AI solutions."
"Our program developer finds it to be a little unstable, development-wise."
"I think it would be good to have more search options such as an index resource. This will provide more options and resources to do advance searches."
"You need integration with other tools to run the query in MongoDB."
"The stability could be improved."
"The solution could have more integration."
"More stable indexes would be helpful in a future release. That's been an issue for some time. I don't know if it's been fixed now but we transitioned to it because we needed a search index to be able to search for things and if that goes or starts disappearing, we have to move away from that solution. I don't know if they fixed it, last time I had this issue was three years ago so they might have solved it."
"I suppose it could be a little more secure."
 

Pricing and Cost Advice

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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 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."
"The solution is open source so is free."
"We use the open-source version, which is available to use free of charge."
"The product is affordable."
"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."
"There is an annual subscription for the use of this solution."
"This is an open-source solution."
"I'm using the free version of MongoDB."
"Our customers pay for yearly licenses for MongoDB."
