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

"I'd rate the solution ten out of ten."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"Some of the valued features of this solution are it has good performance and failover."
"The solution provided us with more than 100K PNRs a second and because the company was international there was a heavy data write, and at the same time a heavy data read."
"If you need availability and consistency, you can go with Cassandra."
"The solution's database capabilities are very good."
"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."
"Our primary use case for the solution is testing."
"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."
"This is a product that I can recommend to others."
"MongoDB has helped my organization by being able to handle large amounts of data."
"I like the document storage feature. It's pretty simple."
"MongoDB is simpler to learn and implement than traditional SQL solutions like MySQL."
"Migrating to MongoDB upgrades the IT environment and puts users in the NoSQL environment, which is faster."
"MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning."
"The solution's most important aspect is its seamless database."
 

Cons

"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."
"The solution is limited to a linear performance."
"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."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"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."
"The secondary index in Cassandra was a bit problematic and could be improved."
"MongoDB should not be used for reporting, analytics, or number-crunching tasks."
"The price can always be better. I mean, we are a big corporation so it is quite expensive for us."
"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."
"The solution should have better integration."
"It should have GUI for managing clusters. MongoDB needs a more powerful GUI to manage clusters and make switchovers. Currently, there is no good, free tool to check the replication to find out if there is a gap."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"MongoDB should incorporate more features, particularly search functionality, and real-time communication capabilities, to improve the database and provide data listening services. Currently, we rely on the Atlas offering, but it would be fantastic if MongoDB could develop a new solution or updated version that includes these features within its internal database and driver. However, I am uncertain if this would be a viable or profitable move for them, and I am speaking from a mobile-centric viewpoint."
"It isn't easy to recognize entities with MongoDB."
 

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."
"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."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"We pay for a license."
"This is an open-source solution."
"It is rather expensive."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"The solution is open source so is free."
"I believe that the licensing fees are paid on a yearly basis."
"There is an annual subscription for the use of this solution."
