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.

Parallel data processing streamlines operations while cost and cloud integration challenge adoption

The cost of the solution is on the more expensive side, which is a concern for me. Additionally, its promotion and interaction with cloud applications are limited. The cloud version is only available in AWS, and in the Middle East, it is not well-developed in the Azure environment. For the cost to be reduced, it should match competitors. Many features need to be incorporated on the cloud.

Quotes from Members

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

Pros

"Some of the valued features of this solution are it has good performance and failover."

"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."

"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."

"Can achieve continuous data without a single downtime because of node to node ring architecture."

"We can add almost one million columns to the solution."

"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."

"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."

"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."

More Cassandra pros

"The most valuable features of the IBM Netezza Performance Server are the NPS server because of the reduced maintenance and overall good performance."

"The benefit is really because of the additional speed that we have and, truth be told, the more updated ETL processes and the revamped scheduler in general."

"The performance is most important to me, and it helps our ability to make business decisions quickly."

"The data governance prospect... from what I've seen, that is a really powerful tool as well, to help with data lineage and keeping track of that."

"We are able to execute very complex queries. Over 90 percent of our query executions are one second or less. We do millions of queries everyday."

"The most valuable feature is the performance."

"The performance of the solution is its most valuable feature. The solution is easy to administer as well. It's very user-friendly. On the technical side, the architecture is simple to understand and you don't need too many administrators to handle the solution."

"For me, as an end-user, everything that I do on the solution is simple, clear, and understandable."

More IBM Netezza Performance Server pros

Cons

"Some issues arise from our vendors like Apache slowness and distribution or load balancing from HAProxy, which should better handle consumption for high-level concurrency."

"There could be more integration, and it could be more user-friendly."

"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."

"Batching bulk data can cause performance issues."

"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."

"Maybe they can improve their performance in data fetching from a high volume of data sets."

"Doesn't support a solution that can give aggregation."

"The disc space is lacking. You need to free it up as you are working."

More Cassandra cons

"This product is being discontinued from IBM, and I would like to have some kind of upgrade available."

"IBM Netezza Performance Server could improve its interface, support for big data, and APA-based connectivity should be available."

"The product cost is high compared to others in the market, and this cost has become unbearable for me."

"Our main problem with it is concurrency. When there are too many users running Netezza at the same time, this is when we have the most complaints."

"We are not able to scale. The only way to scale is to get another appliance, but we have a customers who would need us to hydrate the data between the two appliances, and Netezza does not do that."

"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."

"The Analytics feature should be simplified."

"I'm not sure of IBM's roadmap currently, as the solution is coming up on its end of life."

More IBM Netezza Performance Server cons

Pricing and Cost Advice

"We are using the open-source version of Cassandra, the solution is free."

"We pay for a license."

"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."

"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."

"Expensive to maintain compared to other solutions."

"The pricing is very expensive. It has a lot CPUs with a lot of components in it. It also has built-in redundancy for resiliency reasons."

"For me, mainly, it reduces my costs. It's not only the appliance cost. There are also support costs and a maintenance costs. It does reduce the costs very drastically."

"The solution has a yearly licensing fee, and users have to pay extra for support."

"Netezza is a costly solution. It does serve a specific purpose but it's costlier than what's available in the market, if you go to the cloud."

"The annual licensing fees are twenty-two percent of the product cost."
