Head, Data Integration & Management at a non-profit with 10,001+ employees
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 satisfied with the performance; so far it has done fairly well and there haven't been any complaints."
"The most valuable features of Cassandra are its scaling capabilities and its non-SQL nature capabilities."
"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 the NoSQL database, high performance, and zero-copy streaming."
"The most valuable feature of Cassandra is its fast retrieval. Additionally, the solution can handle large amounts of data. It is the quickest application we use."
"I am getting much better performance than relational databases."
"Cassandra is good, it's better than CouchDB, and we are using it in parallel with CouchDB, as Cassandra looks better and is more user-friendly."
"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."
"From a technical point of view, there are no significant issues recalled as Elastic Search has been absolutely awesome for this use case and covers 100% of the needs."
"The best feature of Elastic Search that I appreciate is its monitoring capability."
"The forced merge and forced resonate features reduce the data size increasing reliability."
"Elastic Search is very user-friendly, and we can easily integrate it with third-party models and other AWS S3 buckets."
"The most valuable features are its user-friendly interface and seamless navigation."
"We had many reasons to implement Elasticsearch for search term solutions. Elasticsearch products provide enterprise landscape support for different areas of the company."
"The solution is very good with no issues or glitches."
"A good use case is saving metadata of your systems for data cataloging. Various systems, like those opened in metadata and similar applications, use Elasticsearch to store their text data."
 

Cons

"Maybe they can improve their performance in data fetching from a high volume of data sets."
"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."
"Cassandra could be more user-friendly like MongoDB."
"Interface is not user friendly."
"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."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"Fine-tuning was a bit of a challenge."
"We have had stability issues including out of memory issues and crashes with earlier versions of the product."
"They could simplify the Filebeat and Logstash configuration piece. There are a lot of manual steps on the operating system."
"The solution's integration and configuration are not easy. Not many people know exactly what to do."
"We'd like more user-friendly integrations."
"Improving machine learning capabilities would be beneficial."
"It needs email notification, similar to what Logentries has."
"I have not been using the solution for many years to know exactly the improvements needed. However, they could simplify how the YML files have to be structured properly."
"Scalability of Elastic Search presents disadvantages, particularly when handling minimal or production-level data."
"Elasticsearch could be improved in terms of scalability."
 

Pricing and Cost Advice

"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 are using the open-source version of Cassandra, the solution is free."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"I use the tool's open-source version."
"We pay for a license."
"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."
"The price of Elasticsearch is fair. It is a more expensive solution, like QRadar. The price for Elasticsearch is not much more than other solutions we have."
"This product is open-source and can be used free of charge."
"The pricing model is questionable and needs to be addressed because when you would like to have the security they charge per machine."
"we are using a licensed version of the product."
"The price of Elastic Enterprise is very, very competitive."
"The cost varies based on factors like usage volume, network load, data storage size, and service utilization. If your usage isn't too extensive, the cost will be lower."
