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 time series data was one of the best features along with auto publishing."
"The technical evaluation is very good."
"We can add almost one million columns to the solution."
"The most valuable feature for us is the technical evaluation, it's the best technology."
"The most valuable features of this solution are its speed and distributed nature."
"Can achieve continuous data without a single downtime because of node to node ring architecture."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"The solution's database capabilities are very good."
"MongoDB stores the JSON data, and it's easy for me to understand because I'm a JavaScript Developer."
"It is really a pretty easy product to use. It's very reliable, it's proven."
"I think the document-based approach is valuable."
"Scalability seems good. I've never been even close to finding the limits. I've run a couple of notes of redundancy but I've never had any problems with scalability."
"MongoDB's best features are scalability, document management, and data security."
"One of the biggest benefits is the speed and flexibility of the documents, especially when it comes to modifications."
"We find the query and speed very valuable."
"It's easy to add and remove things in MongoDB. You can alter the tables. MongoDB is faster at reading, slower at writings."
 

Cons

"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."
"The solution is limited to a linear performance."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"Fine-tuning was a bit of a challenge."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"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."
"We found some issues with the batch inserts when the data volume is large."
"The documentation for MongoDB is not very good and should be improved."
"The free tools, like MongoDB Compass, could be enhanced."
"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."
"The solution could include more integrations with other platforms."
"When I want to connect to a node, I need to supply the certificate that MongoDB trusts, even though I use an admin password."
"The stability could be better."
"The product's data consistency could be more efficient than traditional SQLs."
"The performance can be improved."
 

Pricing and Cost Advice

"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."
"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."
"We use the open-source version, which is available to use free of charge."
"I believe that the licensing fees are paid on a yearly basis."
"I'm using the free version of MongoDB."
"There are different licenses available to be purchased, such as individual, premium, or enterprise."
"The pricing is normal. Price-wise, the product is not too much expensive."
"The product is affordable."
"MongoDB is not expensive."
"You only have to pay for the paid version, not the open-source version."
