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.

The integration between data warehouse could be improved. Nowadays, a lot of data is getting generated, so certain ETL flexible scripts with backend database integrations would be an improvement I could see. I will not be able to clearly say there is currently a deficiency there. All our DBs are integrated with a backend data warehouse, not necessarily AWS. When third-party data warehouses are integrated, we are seeing some ETL job performance issues. It is a one-off scenario so we have not thoroughly done any troubleshooting on that. It could be platform or third-party related issue. From the AWS standpoint, if robust integration and data warehouse integration specific tools are added in the advanced suite, that would definitely be helpful.

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 this solution are its speed and distributed nature."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"Cassandra is a stable solution."
"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."
"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 technical evaluation is very good."
"We have experienced zero downtime using Cassandra, it is highly stable."
"It's used as our cloud based backend store as a temporary cache and for storing data that streams through our data pipe."
"It facilitates the generation of heatmaps for graphical data analysis."
"It is easy to use."
"MongoDB is flexible and it allows other applications to be added."
"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."
"We are using real-time analytics and monitoring in MongoDB Enterprise Advanced; it is integrated—the existing advanced feature is integrated with our business analytics interface, and all the various business intelligence reports are generated from that."
"The most valuable feature of MongoDB is the predefined functions available when using Node.js. These functions simplify the query process, making it user-friendly and straightforward."
"The integration capabilities of MongoDB are fine for the solutions that we use in our company."
"MongoDB's dashboards offer more functionalities and allow you to create a dashboard with MongoDB database data."
 

Cons

"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."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"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 found some issues with the batch inserts when the data volume is large."
"I want Cassandra to update its open-source version more quickly. It's already feature-rich, but I'd appreciate better integration with other NoSQL databases like MariaDB or MongoDB. If I ever need to work with customers or vendors using different NoSQL databases, having native integration in Cassandra would make managing and interacting with their databases much easier."
"The secondary index in Cassandra was a bit problematic and could be improved."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"It has certain limitations when it comes to handling hierarchical data, enforcing relationships, and performing complex joins, which should be taken into account when designing databases for applications with intricate data requirements."
"I think it's very expensive on the Atlas enterprise side."
"There is room for improvement in integrating MongoDB with agentive AI solutions."
"It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy."
"The product's data consistency could be more efficient than traditional SQLs."
"There can be stability issues."
"The analytics needs improvement."
"MongoDB should improve its data loading part."
 

Pricing and Cost Advice

"We pay for a license."
"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"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."
"MongoDB is not expensive."
"You only have to pay for the paid version, not the open-source version."
"Our customers pay for yearly licenses for MongoDB."
"The pricing is favorable if you opt to install MongoDB on an Amazon EC2 instance as you won't have to pay for the extra Atlas services and can instead manage the scaling yourself. This allows for a cost-effective solution and using MongoDB on a small scale, I have been able to utilize it for free."
"There is an enterprise license and it could be cheaper. We are using the free open source version."
"There is an annual subscription for the use of this solution."
"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 only used the open-source version."
