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

"Setup was very straightforward."
"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."
"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 a stable solution."
"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."
"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."
"I am getting much better performance than relational databases."
"MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall."
"It stores historical data with ease. For example, if you are a healthcare member, then you will have multiple records of visits to the doctors. To store such data in Oracle Database, you have to create many records. You might also have duplication problems because your records are going in again and again, because of which the data warehouse and the maintenance cost will be huge. MongoDB is comparatively lightweight. It is a JSON extract. Once you define a schema and extract it, you can push all the relationships in any way you want. It is easier to define and get different types of transactions into MongoDB. It is also easier to set it up as compared to other solutions. MongoDB is a NoSQL database, which means it is a document DB in which you can store documents that you created in BSON. It is pretty fast in response. It is faster than relational databases because it does not define any primary keys, secondary keys, tertiary keys, and all those kinds of things."
"Its flexibility, and cost. It is reasonably priced."
"This is a product that I can recommend to others."
"Based on our experience so far, it is stable."
"MongoDB is relatively fast compared to relational databases."
"I like the schemaless architecture that it follows. I also like the sharding that it provides."
"We use it for website designing, and for mobile app designing just like Adobe XD."
 

Cons

"Interface is not user friendly."
"There could be more integration, and it could be more user-friendly."
"The solution doesn't have joins between tables so you need other tools for that."
"It can be difficult to analyze what's going on inside of the database relative to other databases."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."
"The solution is not easy to use because it is a big database and you have to learn the interface."
"The clustering needs to be better; it is getting there."
"Simplifying the aggregation framework would be an improvement."
"The performance of the solution could be improved."
"It should have GUI for managing clusters. MongoDB needs a more powerful GUI to manage clusters and make switchovers."
"The transaction could use improvement. From MySQL, for example, you cannot create a transaction if you are reading and writing a document at the same time."
"More stable indexes would be helpful in a future release. That's been an issue for some time."
"MongoDB is the second option for non-critical processes at the moment. We do not yet trust it with critical items."
"The product's data consistency could be more efficient than traditional SQLs."
"I suppose it could be a little more secure."
 

Pricing and Cost Advice

"I don't have the specific numbers on pricing, but it was fairly priced."
"We pay for a license."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"We are using the open-source version of Cassandra, the solution is free."
"I believe that MongoDB is free."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"I only used the open-source version."
"At the moment, all customers are using the community version."
"The solution is open source, so it is free."
"MongoDB is an open-source solution."
"It's open-source."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
