Monirul Islam Khan - PeerSpot reviewer
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.
Harshwardhan Gullapalli - PeerSpot reviewer

Semantic search has transformed financial document discovery and supports real-time RAG chat
On the integration side, Pinecone's Python SDK is straightforward. It integrates well with the usual AI stack like LangChain and LlamaIndex. That was smooth for me. Where it could improve is around documentation for edge cases. For instance, handling metadata filtering at scale, understanding the right embedding dimensions for different use cases, and best practices for indexing strategies. Those topics felt sparse in the documentation. More real-world tutorials specific to common patterns like RAG or recommendation systems would help developers ramp up faster. On support, the community is helpful, but if you hit something tricky and you are on a lower-tier plan, getting quick answers can be slow. Better-tiered support or more comprehensive troubleshooting guides would be valuable, especially for production deployments where latency is critical.

Quotes from Members

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

Pros

"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"I'd rate the solution ten out of ten."
"I am satisfied with the performance; so far it has done fairly well and there haven't been any complaints."
"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 its scaling capabilities and its non-SQL nature capabilities."
"We can add almost one million columns to the solution."
"Based on my experience, Cassandra is good for document management system, as well as distributed database system, and the automatic recovery process is there."
"Pinecone is a great platform; it's easy to use with clean SDKs, so it becomes always a go-to option when I think of a vector database."
"Once I switched to vector search with Pinecone, users could find contextually relevant documents much faster."
"The semantic search capability is very good."
"Pinecone has positively impacted our organization by enhancing efficiency for the team, and the long-term effect has been that the chats have become much more personalized due to the memory added through a vector database."
"Pinecone has positively impacted my organization by enabling fast similarity searches using metrics such as cosine or Euclidean distance on billions of vectors with low latency around 20 to 100 milliseconds, with key capabilities including hybrid search combining semantic and keyword, real-time updates, filtering, and re-ranking."
"The best thing about Pinecone is its private local host feature. It displays all the maintenance parameters and lets us view the data sent to the database. We can also see the status of the CD and which application it corresponds to."
"We chose Pinecone because it covers most of the use cases."
"The product's setup phase was easy."
 

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."
"I want Cassandra to update its open-source version more quickly. It's already feature-rich, but I'd appreciate better integration with other NoSQL databases like MariaDB or MongoDB. If I ever need to work with customers or vendors using different NoSQL databases, having native integration in Cassandra would make managing and interacting with their databases much easier."
"We found some issues with the batch inserts when the data volume is large."
"We experience configuration issues when accommodating the volumes we require, which often necessitates consultation with the Cassandra development team."
"Maybe they can improve their performance in data fetching from a high volume of data sets."
"The secondary index in Cassandra was a bit problematic and could be improved."
"If you have a requirement of aggregation and joints, Cassandra doesn't support a solution that can give the aggregation."
"There could be more integration, and it could be more user-friendly."
"I want to suggest that Pinecone requires a login and API key, but I would prefer not to have a login system and to use the environment directly."
"If I were to add something about necessary improvements, I would say reducing the cost, as the vector database cost is significantly higher than a normal MongoDB or any other database cost."
"Onboarding could be better and smoother."
"If Pinecone gave us RAG as a service, we'd be more than happy to use that."
"From a cost perspective, I believe Pinecone is a bit expensive compared to other solutions such as FAISS and Milvus, which are free and open source, while Weaviate is more cost-effective at scale, so I would request improvement in Pinecone's pricing structure."
"Pinecone can be made more budget-friendly."
"The tool does not confirm whether a file is deleted or not."
"The main challenge was not performance itself, it was cost."
 

Pricing and Cost Advice

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"I use the tool's open-source version."
"We pay for a license."
"I don't have the specific numbers on pricing, but it was fairly priced."
"Pinecone is not cheap; it's actually quite expensive. We find that using Pinecone can raise our budget significantly. On the other hand, using open-source options is more budget-friendly."
"I think Pinecone is cheaper to use than other options I've explored. However, I also remember that they offer a paid version."
"I have experience with the tool's free version."
"The solution is relatively cheaper than other vector DBs in the market."
