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

"Our primary use case for the solution is testing."
"The time series data was one of the best features along with auto publishing."
"If you need availability and consistency, you can go with Cassandra."
"I am getting much better performance than relational databases."
"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."
"Setup was very straightforward."
"The most valuable features of this solution are its speed and distributed nature."
"We have experienced zero downtime using Cassandra, it is highly stable."
"MongoDB is cool; there is a difference between relational databases and newer databases like MongoDB, and MongoDB is scalable and fast."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"The most valuable feature of MongoDB is the ease of connections, aggregation, and queries."
"One of the biggest benefits is the speed and flexibility of the documents, especially when it comes to modifications."
"One of the most valuable features is the ability to Text Search can be used anywhere and anytime."
"The clustering is very good. It allows us to have high availability."
"MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall."
"MongoDB is highly stable, and I would rate its stability at nine out of ten."
 

Cons

"Batching bulk data can cause performance issues."
"The solution is limited to a linear performance."
"The clustering needs to be better; it is getting there."
"One of the issues with the solution is that you cannot drop write like you're able to in MongoDB and MySQL, where you can join tables."
"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."
"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"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."
"It would help if MongoDB offered a light solution for small projects."
"The product's data consistency could be more efficient than traditional SQLs."
"It should have GUI for managing clusters. MongoDB needs a more powerful GUI to manage clusters and make switchovers. Currently, there is no good, free tool to check the replication to find out if there is a gap."
"The performance can be improved."
"The scalability of the solution has room for improvement."
"MongoDB has a "heavy" architecture, which limits the scalability options."
"There are some problems with bugs appearing in sharding when the data is too high."
"The MongoDB documentation can be a little complicated sometimes."
 

Pricing and Cost Advice

"We pay for a license."
"We are using the open-source version of Cassandra, the solution is free."
"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."
"I don't have the specific numbers on pricing, but it was fairly priced."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"MongoDB is an open-source product."
"Our customers pay for yearly licenses for MongoDB."
"I believe that the licensing fees are paid on a yearly basis."
"The product is affordable."
"MongoDB is not expensive."
"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."
"It is rather expensive."
"We use the open-source version, which is available to use free of charge."
