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

"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"Our primary use case for the solution is testing."
"We can add almost one million columns to the solution."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"A consistent solution."
"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 reports are useful for controlling the load of our whole architecture."
"like its performance and the stability. It's very stable and, performance-wise, it's really great."
"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."
"MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall."
"We decided to work with MongoDB as its interface is easier to understand and more universal."
"It can handle a lot of files quickly."
"It is easy to use."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
 

Cons

"Maybe they can improve their performance in data fetching from a high volume of data sets."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"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."
"Interface is not user friendly."
"We found some issues with the batch inserts when the data volume is large."
"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."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"Doesn't support a solution that can give aggregation."
"MongoDB is a very useful and convenient choice, but sometimes for more complex projects, there are certain niche requirements that appear, so using a different tool could be beneficial. It raises the complexity of the architecture, but it could be beneficial to the world, the features, the ease of the features which are being implemented."
"I don't see a lot of areas that need improvement."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"Sometimes, the tool goes down temporarily. There are some stability issues in the product."
"From my point of view, they need a totally free IDE to work at high levels."
"Our program developer finds it to be a little unstable, development-wise."
"At the start, connecting to the database via Compass or through a direct ID was a challenge."
"MongoDB should support TypeScript."
 

Pricing and Cost Advice

"We are using the open-source version of Cassandra, the solution is free."
"I use the tool's open-source version."
"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."
"We are using the Community Edition of MongoDB."
"It's open-source."
"It's a community edition, so we do not pay anything."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"I currently use the solution's community edition which is free."
"I only used the open-source version."
"The product is affordable."
