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

"I am getting much better performance than relational databases."
"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."
"We have experienced zero downtime using Cassandra, it is highly stable."
"Its retrieval is similar to an RDBMS, so our team finds it easy to adapt."
"Some of the valued features of this solution are it has good performance and failover."
"Cassandra offers high availability and fault tolerance, making it suitable for large-scale data storage and real-time processing."
"The most valuable features of Cassandra are the NoSQL database, high performance, and zero-copy streaming."
"The most valuable features of the solution are similarity search and maximal marginal relevance search for retrieval purposes."
"The semantic search capability is very good."
"The most valuable feature of Pinecone is its managed service aspect. There are many vector databases available, but Pinecone stands out in the market. It is very flexible, allowing us to input any kind of data dimensions into the platform. This makes it easy to use for both technical and non-technical users."
"We chose Pinecone because it covers most of the use cases."
"Pinecone has positively impacted my organization by helping people in needle-in-a-haystack situations, as previously they had to grind through PDF documents, PowerPoint documents, and websites, but now with Pinecone, they can ask questions and receive references to documents along with the page numbers where that information exists, so they can use it as a reference or backtrack, especially for things such as FDA approvals where they can quote the exact page number from PDF documents, eliminating hallucination and providing real-time data that relies on an external vector database with enough guardrails to ensure it won't provide information not in the vector database, confining it to the information present in the indexes."
"Once I switched to vector search with Pinecone, users could find contextually relevant documents much faster."
"Pinecone was one of the earliest vector databases I came to know about, and it's the go-to option; I suggest it for anyone new to or learning about vector databases because it's very easy to start and work with without needing complex setups."
"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."
 

Cons

"Cassandra is very complex to manage. Sometimes, I need to involve a senior DevOps engineer if we encounter a problem."
"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 could be more integration, and it could be more user-friendly."
"The disc space is lacking. You need to free it up as you are working."
"Depending upon our schema, we can't make ORDER BY or GROUP BY clauses in the product."
"We found some issues with the batch inserts when the data volume is large."
"Cassandra can improve by adding more built-in tools. For example, if you want to do some maintenance activities in the cluster, we have to depend on third-party tools. Having these tools build-in would be e benefit."
"The secondary index in Cassandra was a bit problematic and could be improved."
"For testing purposes, the product should offer support locally as it is one area where the tool has shortcomings."
"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 needs to be upgraded because many companies are not using Pinecone for production."
"Pinecone can be made more budget-friendly."
"If Pinecone could increase the free quota and not kill the free quota after seven days, that would be great."
"Pinecone is good as it is, but had it been on AWS infrastructure, we wouldn't experience some network lags because it's outside AWS."
"Pinecone is not open-source. The cost can escalate based on the pay-as-you-go pricing, so when there are high volume large embeddings, the cost would automatically rise."
 

Pricing and Cost Advice

"Cassandra is a free open source solution, but there is a commercial version available called DataStax Enterprise."
"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."
"I don't have the specific numbers on pricing, but it was fairly priced."
"There are licensing fees that must be paid, but I'm not sure if they are paid monthly or yearly."
"The solution is relatively cheaper than other vector DBs in the market."
"I have experience with the tool's free version."
"I think Pinecone is cheaper to use than other options I've explored. However, I also remember that they offer a paid version."
"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."
