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.

Logging and vector search have transformed observability and empowered reliable ai agents
Elastic Search is not specifically being used for certain purposes. I deploy Elastic Search database on the cloud and use cloud services so that nobody can attack. However, I do not use Elastic Search to resolve attack issues. The basic main purpose of Elastic Search, as of now, I feel it can do more in the AI area. Sometime I saw that when I am developing RAG and have to generate the embeddings, which I call metadata, sometimes it tries to fail. That durability or issue handling should be improved, but apart from that, I did not find anything as of now. As per my use case, whatever I am using seems pretty good. Apart from that, some definitely improvement will be there. One improvement is that it should be faster. Whenever I am searching any logs, it takes much time. For example, if I open my log in Notepad or a similar tool, I can search the text within a second. With Elastic Search, it takes a little bit of time, ten to fifteen seconds. That can be improved. Sometimes, engineers take time to assign when I create a ticket.

Quotes from Members

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

Pros

"Setup was very straightforward."
"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."
"The solution's database capabilities are very good."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"The time series data was one of the best features along with auto publishing."
"I am satisfied with the performance."
"Some of the valued features of this solution are it has good performance and failover."
"What I appreciate about Elastic Search is that the best features include the ability to search through very big documents and index and search through them really fast."
"The full text search capabilities in Elastic Search have proven to be extremely valuable for our operations."
"In the last 18 months Elastic has really caught up and also gone way beyond AWS by putting together all the missing components that make ELK Elasticsearch the most comprehensive stack in the entire Big Data ecosystem."
"One thing I appreciate about Elastic Search is the ability to aggregate everything into one dashboard, so I can have monitoring, logs, and traces in one portal instead of having multiple different tools to do the same."
"Elastic Search has impacted my organization positively as we use it for logging and APM."
"Helps us to store the data in key value pairs and, based on that, we can produce visualisations in Kibana."
"The solution has good security features. I have been happy with the dashboards and interface."
"The initial installation and setup were straightforward."
 

Cons

"Doesn't support a solution that can give aggregation."
"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."
"The secondary index in Cassandra was a bit problematic and could be improved."
"There could be more integration, and it could be more user-friendly."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"The secondary index in Cassandra was a bit problematic and could be improved."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"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."
"The solution's integration and configuration are not easy. Not many people know exactly what to do."
"Performance improvement could come from skipping background refresh on search idle shards (which is already being addressed in the upcoming seventh version)."
"New Relic could be more flexible, similar to Elasticsearch."
"Technical support should be faster."
"The UI point of view is not very powerful because it is dependent on Kibana."
"I think the biggest issue we had with Elastic Search was regarding integrations with our multi-factor authentication tool."
"The reports could improve."
"The reports could improve."

"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 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."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"An X-Pack license is more affordable than Splunk."
"We are using the open-sourced version."
"The solution is affordable."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
