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 most valuable features of this solution are its speed and distributed nature."
"Some of the valued features of this solution are it has good performance and failover."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"The most valuable features are the counter features and the NoSQL schema. It also has good scalability. You can scale Cassandra to any finite level."
"A consistent solution."
"The technical evaluation is very good."
"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 reports are useful for controlling the load of our whole architecture."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"MongoDB is flexible and it allows other applications to be added."
"The clustering is very good. It allows us to have high availability."
"Easier to maintain the data with its document-based storage."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"The most valuable features of MongoDB are the variety of translations available and the ability to deploy it on the cloud is useful. The cloud users can access the data, work on the data, and if they want to import or manipulate some data they can."
"We are using real-time analytics and monitoring in MongoDB Enterprise Advanced; it is integrated—the existing advanced feature is integrated with our business analytics interface, and all the various business intelligence reports are generated from that."
 

Cons

"Maybe they can improve their performance in data fetching from a high volume of data sets."
"The secondary index in Cassandra was a bit problematic and could be improved."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"Cassandra can improve by adding more built-in tools. For example, if you want to do some maintenance activities in the cluster, we have to depend on third-party tools. Having these tools build-in would be e benefit."
"Cassandra could be more user-friendly like MongoDB."
"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."
"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."
"The disc space is lacking. You need to free it up as you are working."
"MongoDB should be more stable, and support should be more efficient."
"I don't see a lot of areas that need improvement."
"The analytics needs improvement."
"The scalability of the solution has room for improvement."
"The stability could be better."
"I rate the support from MongoDB a four out of five."
"At the start, connecting to the database via Compass or through a direct ID was a challenge."
"The solution could have more integration."
 

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."
"We pay for a license."
"I don't have the specific numbers on pricing, but it was fairly priced."
"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."
"I only used the open-source version."
"MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"You only have to pay for the paid version, not the open-source version."
"Our customers pay for yearly licenses for MongoDB."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"We use the open-source version, which is available to use free of charge."
"MongoDB is an open-source product."
