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

"The technical evaluation is very good."
"Some of the valued features of this solution are it has good performance and failover."
"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."
"I am satisfied with the performance."
"I am getting much better performance than relational databases."
"Our primary use case for the solution is testing."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"The installation is very easy to do and understand."
"The aggregation framework is very powerful when elaborating on data."
"The Dynamic Application is a valuable feature."
"It is very easy to create a MongoDB cluster. You can deploy three nodes in one hour. You can do small configurations to enable routing. It is easy to implement."
"The initial setup isn't really that complex."
"I like that MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"The reports are useful for controlling the load of our whole architecture."
 

Cons

"The secondary index in Cassandra was a bit problematic and could be improved."
"Batching bulk data can cause performance issues."
"Cassandra could be more user-friendly like MongoDB."
"There could be more integration, and it could be more user-friendly."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"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."
"The solution doesn't have joins between tables so you need other tools for that."
"Fine-tuning was a bit of a challenge."
"Lacks sufficient scalability and elasticity."
"I would recommend MongoDB as part of a template if anyone is considering free and open-source templating services such as LibreNMS, but as a standalone, I couldn't advise."
"I'd like to see an ID generator. It's very technical but I don't think it has one, so we have to go to great lengths to work around that."
"I think that MongoDB's search engine should be improved."
"The stability could be improved."
"Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use."
"They could provide more documentation and examples for adding pipeline stages."
"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."
 

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."
"I don't have the specific numbers on pricing, but it was fairly priced."
"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."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"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."
"The product is affordable."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"I currently use the solution's community edition which is free."
"MongoDB is an open-source product."
"The pricing is normal. Price-wise, the product is not too much expensive."
