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

"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 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."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"The solution's database capabilities are very good."
"The most valuable features of this solution are its speed and distributed nature."
"I am satisfied with the performance."
"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"The reports are useful for controlling the load of our whole architecture."
"MongoDB's best features are scalability, document management, and data security."
"MongoDB's approach to handling data in documents rather than traditional tables has been particularly beneficial."
"It can handle a lot of files quickly."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"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."
"It is easy to use."
"I value the API integrations."
 

Cons

"Fine-tuning was a bit of a challenge."
"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."
"Interface is not user friendly."
"The solution is limited to a linear performance."
"Batching bulk data can cause performance issues."
"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"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."
"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."
"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."
"There is a need for improvement in MongoDB's customer support."
"The dashboard is an area of concern in the solution where improvements are required."
"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."
"The improvements could be made to intelligence to detect disk storage and prevent MongoDB from crashing."
"I think that MongoDB's search engine should be improved."
"I rate the support from MongoDB a four out of five."
 

Pricing and Cost Advice

"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"We are using the open-source version of Cassandra, the solution is free."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"I'm using the free version of MongoDB."
"This is an open-source solution."
"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."
"Our customers pay for yearly licenses for MongoDB."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"The product is affordable."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"It's a community edition, so we do not pay anything."
