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

"I am getting much better performance than relational databases."
"If you need availability and consistency, you can go with Cassandra."
"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."
"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 time series data was one of the best features along with auto publishing."
"I am satisfied with the performance."
"Overall, I would rate Cassandra as nine because of its fast writes, which really suit our use cases mostly."
"It is a stable and good platform."
"I appreciate that Elastic Enterprise Search is easy to use and that we have people on our team who are able to manage it effectively."
"The most valuable features of Elastic Enterprise Search are it's cloud-ready and we do a lot of infrastructure as code. By using ELK, we're able to deploy the solution as part of our ISC deployment."
"Big businesses cannot survive without Elastic Search because it gives us very good visibility and handles our use cases very well."
"ELK Elasticsearch is definitely a stable solution; it is the spec that surprises most of the other logging solutions in the market."
"This product has notably improved the way we store and use logs, from having a more user-friendly, centralized solution (for those who just needed a quick glance, without being masters of sed and awk) to implementing various mechanisms for machine-learning from our logs, and sending alerts for anomalies."
"The Attack Discovery feature helps to dig into incidents from where they occurred to determine how the incident originated and its source; it gives an entire path of attack propagation, showing when it started, what happened, and all events that took place to connect the entire cyber incident."
"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."
 

Cons

"There could be more integration, and it could be more user-friendly."
"The clustering needs to be better; it is getting there."
"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"The disc space is lacking. You need to free it up as you are working."
"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."
"There were challenges with the query language and the development interface. The query language, in particular, could be improved for better optimization. These challenges were encountered while using the Java SDK."
"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"The interface could definitely be improved. It's a technical database and for me the features are not user friendly."
"The different applications need to be individually deployed."
"I would like to see more integration for the solution with different platforms."
"They could simplify the Filebeat and Logstash configuration piece. There are a lot of manual steps on the operating system."
"Elastic Search has limitations for handling huge amounts of data and updates, especially if updates are frequent."
"I see that there are areas in Elastic Search that have room for improvement, such as user documentation and onboarding processes."
"I want the solution to improve the graph feature because it is a little bit poor."
"The upgrade experience and inflexibility with fields keeps Elastic Search from being a perfect 10."
"The solution must provide AI integrations."
 

Pricing and Cost Advice

"I use the tool's open-source version."
"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."
"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."
"An X-Pack license is more affordable than Splunk."
"The solution is less expensive than Stackdriver and Grafana."
"The price could be better."
"The solution is free."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"We are using the free open-sourced version of this solution."
"We use the free version for some logs, but not extensive use."
"It can move from $10,000 US Dollars per year to any price based on how powerful you need the searches to be and the capacity in terms of storage and process."
