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."
"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 technical evaluation is very good."
"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."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"Its flexibility, and cost. It is reasonably priced."
"I like the document storage feature. It's pretty simple."
"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."
"One of the first things I noticed when I had my first experience with MongoDB was how easy it was to use. I was expecting more difficulties or at least some challenges, but it was very, very easy to use. It's great technology, performs well, and is very convenient."
"The reports are useful for controlling the load of our whole architecture."
"In our case, it is most important to have redundancy."
"We decided to work with MongoDB as its interface is easier to understand and more universal."
"I like the schemaless architecture that it follows. I also like the sharding that it provides."
 

Cons

"Cassandra could be more user-friendly like MongoDB."
"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."
"Interface is not user friendly."
"Fine-tuning was a bit of a challenge."
"Doesn't support a solution that can give aggregation."
"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."
"The secondary index in Cassandra was a bit problematic and could be improved."
"The solution is limited to a linear performance."
"The solution should more easily integrate with custom code."
"The dashboard is an area of concern in the solution where improvements are required."
"It has certain limitations when it comes to handling hierarchical data, enforcing relationships, and performing complex joins, which should be taken into account when designing databases for applications with intricate data requirements."
"I would like to see the scalability and security improved."
"Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use."
"MongoDB should not be used for reporting, analytics, or number-crunching tasks."
"Lacks sufficient scalability and elasticity."
"It would be much more useful if I have an admin user and a password."
 

Pricing and Cost Advice

"I don't have the specific numbers on pricing, but it was fairly priced."
"I use the tool's open-source version."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"We pay for a license."
"We are using the open-source version of Cassandra, the solution is free."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"The solution is open source so is free."
"MongoDB is an open-source solution."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"It's a community edition, so we do not pay anything."
"MongoDB is a bit expensive compared to its competitors."
"I believe that the licensing fees are paid on a yearly basis."
"MongoDB's pricing is reasonable."
