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.

Document data has streamlined prototyping and now supports secure cloud deployments
I use the cloud version of the product. MongoDB Enterprise Advanced is from MongoDB, though I also use DigitalOcean as a third-party provider. Maybe it's all more about preferences. I think MongoDB Enterprise Advanced has weak support on the ORM side, particularly if you're using Prisma. I think mostly the focus now on the tools we have is PostgreSQL. MongoDB Enterprise Advanced is not really used that much on our side for production. It's not really a weak point. It's more of a double-edged sword. If you like document-based management databases and you don't want any migrations, then you go to MongoDB Enterprise Advanced. If you want more secure databases, then you use SQL. On the account management and the way you secure the connection strings, I have utilized advanced security features with MongoDB Enterprise Advanced. I think it's very expensive on the Atlas enterprise side. But if you go to other providers of MongoDB Enterprise Advanced, such as DigitalOcean, it may be harder to set up, but they can save you money.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Ability to achieve write speeds 10k tps: Compared to existing, it is 300% percent higher."
"We can add almost one million columns to the solution."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"Since I haven't had years of experience with it, it's still new to me. One valuable feature is its distribution, so I can run it partly in the cloud and part on-prem. That's a feature I'd like to use but haven't yet because we're trying to move to Azure. I don't know if or when that will happen. Ideally, we'd have it distributed over the cloud and on-prem simultaneously, so if something happens to our on-prem, we can keep going in the cloud, like a pay-as-you-go model with Azure."
"Our primary use case for the solution is testing."
"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 most valuable feature for us is the technical evaluation, it's the best technology."
"The solution's database capabilities are very good."
"Migrating to MongoDB upgrades the IT environment and puts users in the NoSQL environment, which is faster."
"It's easy to use."
"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."
"MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning."
"I like its performance and the stability; it's very stable and, performance-wise, it's really great."
"The reports are useful for controlling the load of our whole architecture."
"I find the integration with other tools very easy."
"I like the schemaless architecture that it follows. I also like the sharding that it provides."
 

Cons

"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 clustering needs to be better; it is getting there."
"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."
"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."
"Cassandra could be more user-friendly like MongoDB."
"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."
"Row-level locking is not available; might be very helpful in update use cases."
"MongoDB would be improved with more integration, particularly for cloud environments like Google BigQuery."
"It would be much more useful if I have an admin user and a password."
"I'd like to see an ID generator. It's very technical but I don't think it has one, so we have to go to great lengths to work around that."
"The solution could include more integrations with other platforms."
"The auto transaction feature is something that I found a little bit problematic. If we want to run two or three transactions at a time, we get write conflicts. So, it becomes really difficult when concurrency comes into the picture."
"You need integration with other tools to run the query in MongoDB."
"The solution could have more integration."
"MongoDB should improve its data loading part."
 

Pricing and Cost Advice

"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."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"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 different licenses available to be purchased, such as individual, premium, or enterprise."
"You only have to pay for the paid version, not the open-source version."
"We are using the Community Edition of MongoDB."
"MongoDB's pricing is not reasonable, but it is not as expensive as the others."
"I currently use the solution's community edition which is free."
"It's a community edition, so we do not pay anything."
"MongoDB is not expensive."
"MongoDB's pricing is reasonable."
