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.

Real-time analytics has transformed daily decisions and delivers fast dashboards from streaming data
The best features SingleStore offers include fast data recovery and data compression by 80 percent. Having the information in sheets helps me to process the information quickly. Simplicity in T-SQL is another aspect I appreciate. Data recovery and sheet-based processing help my team on a day-to-day basis by enabling us to handle information efficiently. I would like to add that the data compression by 80 percent helps us in an excellent way since we are very fast in obtaining the data for our dashboards and the compression of the information is great. SingleStore has impacted my organization positively by enabling us to run low-latency analytics and model-driven use cases at scale, which is quite difficult for OLAP and OLTP databases alone. It has been very helpful because our internal clients are happy to have the data and make data-driven decisions easily. Making decisions based on data within a two-hour delay to the transactional database is excellent since we went from twenty-four hours to two hours. I think the best contribution is decision-making with data that is close to reality. Reducing that delay from twenty-four hours to two hours has significantly affected my team and business outcomes by increasing productivity. We have been able to serve all our customers, and they are very happy. We can deliver to them on time.

Quotes from Members

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

Pros

"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 solution provided us with more than 100K PNRs a second and because the company was international there was a heavy data write, and at the same time a heavy data read."
"The technical evaluation is very good."
"Cassandra has some features that are more useful for specific use cases where you have time series where you have huge amounts of writes. That should be quick, but not specifically the reads. We needed to have quicker reads and writes and this is why we are using Cassandra right now."
"I'd rate the solution ten out of ten."
"If you need availability and consistency, you can go with Cassandra."
"The solution's database capabilities are very good."
"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."
"After moving to SingleStore, we definitely managed to speed things up and reduce costs because we do not need to have many tables split by month as in SQL Server."
"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."
"SingleStore is a pretty good database engine set up to handle very large loads of both transactions and data, and it is very easy to use."
"The product can automatically reinstall and reconfigure in case of a shutdown."
"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."
"The paramount advantage is the exceptional speed."
"SingleStore has impacted my organization positively because the output and performance of the app have been improved."
 

Cons

"There could be more integration, and it could be more user-friendly."
"The solution doesn't have joins between tables so you need other tools for that."
"The secondary index in Cassandra was a bit problematic and could be improved."
"We found some issues with the batch inserts when the data volume is large."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."
"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."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"I have noticed that SingleStore can be improved because the integration of SingleStore with DataDog is not good."
"In my opinion, SingleStore could be improved, and we are talking about this directly with SingleStore."
"SingleStore is very well at the current stage, but I see room for improvement in ease of administration, monitoring, and reducing troubleshooting time."
"If you are going for self-managed, you need to set up a solid backup pipeline with SingleStore support, which was my only dissatisfaction, but after doing what was needed, we have very good backup and restore pipelines running, and in Helios, everything is perfect."
"We don't get good discounts in Pakistan."
"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."
"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."
"Having the ability to migrate servers using a single command would be extremely beneficial."
 

Pricing and Cost Advice

"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."
"We pay for a license."
"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."
"I don't have the specific numbers on pricing, but it was fairly priced."
"They have two main options: cloud installation and bare-metal installation, each with different pricing models."
"I would advise users to try the free 128GB version."
"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
"SingleStore is a bit expensive."
"The product's licensing is not expensive. It is comparable."
