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

"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."
"If you need availability and consistency, you can go with Cassandra."
"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."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."
"I am satisfied with the performance."
"It's used as our cloud based backend store as a temporary cache and for storing data that streams through our data pipe."
"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."
"I like that MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"We are talking about a rapid activity and replication solution which serves our needs well."
"It can handle a lot of files quickly."
"The most valuable features of MongoDB are we have a lot of documentation and SQL-based applications that run on it."
"The solution's most important aspect is its seamless database."
"In our case, it is most important to have redundancy."
"MongoDB is cool; there is a difference between relational databases and newer databases like MongoDB, and MongoDB is scalable and fast."
"This is a product that I can recommend to others."
 

Cons

"Row-level locking is not available; might be very helpful in update use cases."
"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."
"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."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"We found some issues with the batch inserts when the data volume is large."
"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 experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"The solution doesn't have joins between tables so you need other tools for that."
"The auto transaction feature is something that I found a little bit problematic. If we want to run two or three transactions at a time, we get write conflicts. So, it becomes really difficult when concurrency comes into the picture."
"I feel that most people don't know a lot about MongoDB, so maybe they could add some more documentation and tutorials."
"There should be better integration with other databases."
"There is an enterprise license and it could be cheaper."
"I think that MongoDB's search engine should be improved."
"MongoDB has a "heavy" architecture, which limits the scalability options."
"It would be good to have scalability for clusters. For example, if we have three clusters, we should be able to increase to five clusters if required. I am not sure if such a feature is currently there. I hope there is good documentation for this."
"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."
 

Pricing and Cost Advice

"We pay for a license."
"I don't have the specific numbers on pricing, but it was fairly priced."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"I use the tool's open-source version."
"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."
"MongoDB is not expensive."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"I believe that the licensing fees are paid on a yearly basis."
"We use the open-source version, which is available to use free of charge."
"MongoDB is a bit expensive compared to its competitors."
"You only have to pay for the paid version, not the open-source version."
"I'm using the free version of MongoDB."
"We are using the Community Edition of MongoDB."
