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 technical evaluation is very good."
"I am getting much better performance than relational databases."
"The most valuable features are the counter features and the NoSQL schema, and it also has good scalability because you can scale Cassandra to any infinite level."
"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 most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"If you need availability and consistency, you can go with Cassandra."
"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."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"The solution does not hold data in tabular format like SQL does but rather clusters data so that it can link on a large scale."
"The most valuable feature is that you can store unstructured data, which is helpful when you don't know what the best structure should be and you cannot use a relational database because of that."
"The solution is user-friendly with a good object retrieval feature."
"MongoDB is a document database that we use for internet applications, logs, and all kinds of things that need quick answers, especially in the document area."
"We can define security rules at the database level or the cluster level to grant or deny access to particular users."
"Opting for MongoDB could be beneficial, especially for storing large volumes of records, even for transient data."
"MongoDB is the best choice for us when we want to store NoSQL-type data."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
 

Cons

"Cassandra could be more user-friendly like MongoDB."
"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."
"The disc space is lacking. You need to free it up as you are working."
"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"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."
"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."
"We found some issues with the batch inserts when the data volume is large."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"The pricing is expensive. MongoDB should better support small and medium companies."
"The solution could have more integration."
"The performance can be improved."
"There is a need for improvement in MongoDB's customer support."
"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."
"There is an enterprise license and it could be cheaper."
"MongoDB should not be used for reporting, analytics, or number-crunching tasks."
"I think it would be good to have more search options such as an index resource. This will provide more options and resources to do advance searches."
 

Pricing and Cost Advice

"We pay for a license."
"I don't have the specific numbers on pricing, but it was fairly priced."
"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."
"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."
"It's open-source."
"I currently use the solution's community edition which is free."
"This is an open-source solution."
"The solution is open source so is free."
"We use the open-source version, which is available to use free of charge."
"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."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"Our customers pay for yearly licenses for MongoDB."
