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 Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"I'd rate the solution ten out of ten."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"I am getting much better performance than relational databases."
"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."
"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."
"The technical evaluation is very good."
"The most valuable features of MongoDB include the flexible schema for storing data, its replication capabilities with high availability through a replica set setup, and horizontal scalability using sharding."
"The community is great if you have problem."
"We decided to work with MongoDB as its interface is easier to understand and more universal."
"We put MongoDB on AWS for a specific project, and it's easy to use."
"The geospatial index feature is useful for dealing with latitude and longitude data."
"We haven't had any issues with stability."
"The stability of the solution is very good, there are no bugs or glitches, it doesn't crash or freeze, and it's pretty good overall."
"Migrating to MongoDB upgrades the IT environment and puts users in the NoSQL environment, which is faster."
 

Cons

"We found some issues with the batch inserts when the data volume is large."
"Cassandra could be more user-friendly like MongoDB."
"It can be difficult to analyze what's going on inside of the database relative to other databases. It can also be difficult to troubleshoot sometimes."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"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."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"The solution is limited to a linear performance."
"The solution could have more integration."
"The user interface is not as friendly as Oracle, which is something that can be improved."
"The solution should have better integration."
"I don't see a lot of areas that need improvement."
"We'd like technical support to respond faster to queries."
"The performance could be faster."
"The on-premises version of the solution is still pretty expensive, especially compared to the cloud version."
"It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy. For example, creating an index is simple in Oracle. In MongoDB, it's quite challenging to do that. Performance could be better. It's fast and good, but you cannot put every application that you would like to in MongoDB."
 

Pricing and Cost Advice

"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."
"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 don't have the specific numbers on pricing, but it was fairly priced."
"We pay for a license."
"I'm using the free version of MongoDB."
"At the moment, all customers are using the community version."
"We are using the Community Edition of MongoDB."
"I currently use the solution's community edition which is free."
"I believe that the licensing fees are paid on a yearly basis."
"I believe that MongoDB is free."
"I don't know, but I have heard from people who procure it that it is much cheaper than Oracle."
"It is rather expensive."
