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

"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"I am satisfied with the performance."
"Cassandra is good. It's better than CouchDB, and we are using it in parallel with CouchDB. Cassandra looks better and is more user-friendly."
"The time series data was one of the best features along with auto publishing."
"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"The use of Cassandra in real-time data analytics has been pivotal for our e-commerce platform. As our platform operates 24/7, providing services to sellers and customers alike, the need for real-time updates is paramount."
"Our primary use case for the solution is testing."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"We find the query and speed very valuable."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
"The most valuable feature of MongoDB is the NoSQL database. In a SQL database, we need to join data together with a unique ID amongst other things, but in MongoDB, it's not required. We can directly receive all the information. The performance is very good. Additionally, they have frequent updates."
"It facilitates the generation of heatmaps for graphical data analysis."
"One of the biggest benefits is the speed and flexibility of the documents, especially when it comes to modifications."
"MongoDB is cool. There is a difference between relational databases and newer databases like MongoDB. MongoDB is scalable and fast."
"MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall."
 

Cons

"Doesn't support a solution that can give aggregation."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"There could be more integration, and it could be more user-friendly."
"The disc space is lacking. You need to free it up as you are working."
"Fine-tuning was a bit of a challenge."
"The solution doesn't have joins between tables so you need other tools for that."
"We found some issues with the batch inserts when the data volume is large."
"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 scalability of the solution has room for improvement."
"Some of the solution's transaction capabilities can be improved."
"It would be much more useful if I have an admin user and a password."
"We'd like information about client onboarding experience and success stories. It would help to have something to show to internal stakeholders."
"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."
"The solution should have better integration."
"Its security features can be better. Sometimes, my higher authority says that we are not going to use MongoDB because it doesn't provide that much security for the RDBMS or relational data that we use for transactions. Instead of MongoDB, we will use Oracle Database because for a transactional service, you have to rely on RDBMS ACID properties. I would love to work on MongoDB by using my mobile phone. When I am working remotely or traveling and have some instances deployed on my server, I should be able to check through my mobile whether all the data is being pulled. GitHub has a similar feature, where it lets you read from the laptop, and you can also pull and push with your mobile phone. I would request MongoDB to provide such a feature. Basically, I want a mobile version for both iOS and Android versions."
"MongoDB should improve its data loading part."
 

Pricing and Cost Advice

"I use the tool's open-source version."
"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 are using the open-source version of Cassandra, the solution is free."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"We pay for a license."
"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."
"I believe that the licensing fees are paid on a yearly basis."
"It is rather expensive."
"I believe that MongoDB is free."
"MongoDB is a free solution. We wanted to have high availability and the subscription cost was quite expensive because the basic one is free and then when you want to have some other replications or other features you will need to pay money. Overall the solution is expensive."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"MongoDB is an open-source product."
"There is an annual subscription for the use of this solution."
